[PMID: 39193251 PMCID: PMC11347041 DOI: 10.1016/j.synbio.2024.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2024] [Revised: 07/24/2024] [Accepted: 07/26/2024] [Indexed: 08/29/2024] Open
Abstract
Ceramides, formed by the dehydration of long-chain fatty acids with phytosphingosine and its derivatives, are widely used in skincare, cosmetics, and pharmaceuticals. Due to the exceedingly low concentration of phytosphingosine in plant seeds, relying on the extraction method is highly challenging. Currently, the primary method for obtaining phytosphingosine is the deacetylation of tetraacetyl phytosphingosine (TAPS) derived from fermentation. Wickerhamomyces ciferrii, an unconventional yeast from the pods of Dipteryx odorata, is the only known microorganism capable of naturally secreting TAPS, which is of great industrial value. In recent years, research and applications focused on modifying W. ciferrii for TAPS overproduction have increased rapidly. This review first describes the discovery history, applications, microbial synthesis pathway of TAPS. Research progress in using haploid breeding, mutagenesis breeding, and metabolic engineering to improve TAPS production is then summarized. In addition, the future prospects of TAPS production using the W. ciferrii platform are discussed in light of the current progress, challenges, and trends in this field. Finally, guidelines for future researches are also emphasized.

Abstract
Metabolic Engineering of yeast is a critical approach to improving the production capacity of cell factories. To obtain genetically stable recombinant strains, the exogenous DNA is preferred to be integrated into the genome. Previously, we developed a Golden Gate toolkit YALIcloneNHEJ, which could be used as an efficient modular cloning toolkit for the random integration of multigene pathways through the innate non-homologous end-joining repair mechanisms of Yarrowia lipolytica. We expanded the toolkit by designing additional building blocks of homologous arms and using CRISPR technology. The reconstructed toolkit was thus entitled YALIcloneHR and designed for gene-specific knockout and integration. To verify the effectiveness of the system, the gene PEX10 was selected as the target for the knockout. This system was subsequently applied for the arachidonic acid production, and the reconstructed strain can accumulate 4.8% of arachidonic acid. The toolkit will expand gene editing technology in Y. lipolytica, which would help produce other chemicals derived from acetyl-CoA in the future.

Abstract
The ability to precisely edit genomes by deleting or adding genetic information enables the study of biological functions and the building of efficient cell factories. In many unconventional yeasts, such as those promising new hosts for cell factory design but also human pathogenic yeasts and food spoilers, this progress has been limited by the fact that most yeasts favour non-homologous end joining (NHEJ) over homologous recombination (HR) as a DNA repair mechanism, impairing genetic access to these hosts. In mammalian cells, small molecules that either inhibit proteins involved in NHEJ, enhance protein function in HR, or arrest the cell cycle in HR-dominant phases are regarded as promising agents for the simple and transient increase of HR-mediated genome editing without the need for a priori host engineering. Only a few of these chemicals have been applied to the engineering of yeast, although the targeted proteins are mostly conserved, making chemical agents a yet-underexplored area for enhancing yeast engineering. Here, we consolidate knowledge of the available small molecules that have been used to improve HR efficiency in mammalian cells and the few ones that have been used in yeast. We include available high-throughput-compatible NHEJ/HR quantification assays that could be used to screen for and isolate yeast-specific inhibitors.

Int J Mol Sci 2023; 24:17366. [PMID: 38139198 PMCID: PMC10743872 DOI: 10.3390/ijms242417366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/05/2023] [Accepted: 12/09/2023] [Indexed: 12/24/2023] Open
Abstract
β-Farnesene is an advanced molecule with promising applications in agriculture, the cosmetics industry, pharmaceuticals, and bioenergy. To supplement the shortcomings of rational design in the development of high-producing β-farnesene strains, a Metabolic Pathway Design-Fermentation Test-Metabolomic Analysis-Target Mining experimental cycle was designed. In this study, by over-adding 20 different amino acids/nucleobases to induce fluctuations in the production of β-farnesene, the changes in intracellular metabolites in the β-farnesene titer-increased group were analyzed using non-targeted metabolomics. Differential metabolites that were detected in each experimental group were selected, and their metabolic pathways were located. Based on these differential metabolites, targeted strain gene editing and culture medium optimization were performed. The overexpression of the coenzyme A synthesis-related gene pantothenate kinase (PanK) and the addition of four mixed water-soluble vitamins in the culture medium increased the β-farnesene titer in the shake flask to 1054.8 mg/L, a 48.5% increase from the initial strain. In the subsequent fed-batch fermentation, the β-farnesene titer further reached 24.6 g/L. This work demonstrates the tremendous application value of metabolomics analysis for the development of industrial recombinant strains and the optimization of fermentation conditions.

Abstract
β-Farnesene is a sesquiterpene commonly found in essential oils of plants, with applications spanning from agricultural pest control and biofuels to industrial chemicals. The use of renewable substrates in microbial cell factories offers a sustainable approach to β-farnesene biosynthesis. In this study, malic enzyme from Mucor circinelloides was examined for NADPH regeneration, concomitant with the augmentation of cytosolic acetyl-CoA supply by expressing ATP-citrate lyase from Mus musculus and manipulating the citrate pathway via AMP deaminase and isocitrate dehydrogenase. Carbon flux was modulated through the elimination of native 6-phosphofructokinase, while the incorporation of an exogenous non-oxidative glycolysis pathway served to bridge the pentose phosphate pathway with the mevalonate pathway. The resulting orthogonal precursor supply pathway facilitated β-farnesene production, reaching 810 mg/L in shake-flask fermentation. Employing optimal fermentation conditions and feeding strategy, a titer of 28.9 g/L of β-farnesene was attained in a 2 L bioreactor.

Abstract
Yarrowia lipolytica is a non-conventional oleaginous yeast with great potential for industrial production. Y. lipolytica has a high propensity for flux through tricarboxylic acid cycle intermediates. Therefore, this host is currently being developed as a workhorse, and is rapidly emerging in biotechnology fields, especially for industrial chemical production, whole-cell bioconversion, and the treatment and recycling of industrial waste. In recent studies, Y. lipolytica has been rewritten and introduced with non-native metabolites of certain compounds of interest owing to the advancement in synthetic biology tools. In this review, we collate recent progress to present a detailed and insightful summary of the major developments in synthetic biology tools and techniques for Y. lipolytica, including promoters, terminators, selection markers, autonomously replicating sequences, DNA assembly techniques, genome editing techniques, and subcellular organelle engineering. This comprehensive overview would be a useful resource for future genetic engineering studies to improve the yield of desired metabolic products in Y. lipolytica.

Abstract
Amorphadiene is the precursor to synthesize the antimalarial drug artemisinin. The production of amorphadiene and artemisinin from metabolically engineered microbes may provide an alternate to plant secondary metabolite extraction. Microbial consortia can offer division of labor, and microbial co-culture system can be leveraged to achieve cost-efficient production of natural products. Using a co-culture system of Y. lipolytica Po1f and Po1g strains, subcellular localization of ADS gene (encoding amorphadiene synthase) into the endoplasmic reticulum, co-utilization of mixed carbon source, and enlargement of the endoplasmic reticulum (ER) surface area, we were able to significantly improve amorphadiene production in this work. Using Po1g/PPtM and Po1f/AaADSERx3/iGFMPDU strains and co-utilization of 5 µM sodium acetate with 20 g/L glucose in YPD media, amorphadiene titer were increased to 65.094 mg/L. The enlargement of the ER surface area caused by the deletion of the PAH1 gene provided more subcellular ER space for the action of the ADS-tagged gene. It further increased the amorphadiene production to 71.74 mg/L. The results demonstrated that the importance of the spatial localization of critical enzymes, and manipulating metabolic flux in the co-culture of Y. lipolytica can be efficient over a single culture for the bioproduction of isoprenoid-related secondary metabolites in a modular manner.

Abstract
Thanks to its sophistication, the CRISPR/Cas system has been a widely used yeast genome editing method. However, CRISPR methods generally rely on preassembled DNAs and extra cloning steps to deliver gRNA, Cas protein, and donor DNA. These laborious steps might hinder its usefulness. Here, we propose an alternative method, Assembly and CRISPR-targeted in vivo Editing (ACtivE), that only relies on in vivo assembly of linear DNA fragments for plasmid and donor DNA construction. Thus, depending on the user's need, these parts can be easily selected and combined from a repository, serving as a toolkit for rapid genome editing without any expensive reagent. The toolkit contains verified linear DNA fragments, which are easy to store, share, and transport at room temperature, drastically reducing expensive shipping costs and assembly time. After optimizing this technique, eight loci proximal to autonomously replicating sequences (ARS) in the yeast genome were also characterized in terms of integration and gene expression efficiencies and the impacts of the disruptions of these regions on cell fitness. The flexibility and multiplexing capacity of the ACtivE were shown by constructing a β-carotene pathway. In only a few days, >80% integration efficiency for single gene integration and >50% integration efficiency for triplex integration were achieved on Saccharomyces cerevisiae BY4741 from scratch without using in vitro DNA assembly methods, restriction enzymes, or extra cloning steps. This study presents a standardizable method to be readily employed to accelerate yeast genome engineering and provides well-defined genomic location alternatives for yeast synthetic biology and metabolic engineering purposes.

Abstract
![]()
As redesigning organisms using engineering principles
is one of
the purposes of synthetic biology (SynBio), the standardization of
experimental methods and DNA parts is becoming increasingly a necessity.
The synthetic biology community focusing on the engineering of Saccharomyces cerevisiae has been in the foreground in this
area, conceiving several well-characterized SynBio toolkits widely
adopted by the community. In this review, the molecular methods and
toolkits developed for S. cerevisiae are discussed
in terms of their contributions to the required standardization efforts.
In addition, the toolkits designed for emerging nonconventional yeast
species including Yarrowia lipolytica, Komagataella
phaffii, and Kluyveromyces marxianus are
also reviewed. Without a doubt, the characterized DNA parts combined
with the standardized assembly strategies highlighted in these toolkits
have greatly contributed to the rapid development of many metabolic
engineering and diagnostics applications among others. Despite the
growing capacity in deploying synthetic biology for common yeast genome
engineering works, the yeast community has a long journey to go to
exploit it in more sophisticated and delicate applications like bioautomation.

Abstract
With the rapid development of synthetic biology, the oleaginous yeast Yarrowia lipolytica has become an attractive microorganism for chemical production. To better optimize and reroute metabolic pathways, we have expanded the CRISPR-based gene expression toolkit of Y. lipolytica. By sorting the integration sites associated with high expression, new neutral integration sites associated with high expression and high integration efficiency were identified. Diverse genetic components, including promoters and terminators, were also characterized to expand the expression range. We found that in addition to promoters, the newly characterized terminators exhibited large variations in gene expression. These genetic components and integration sites were then used to regulate genes involved in the lycopene biosynthesis pathway, and different levels of lycopene production were achieved. The CRISPR-based gene expression toolkit developed in this study will facilitate the genetic engineering of Y. lipolytica.

Abstract
Klebsiella pneumoniae simultaneously carrying genes encoding carbapenem resistance and hypervirulence causes fatal infections, representing a severe threat to human health. These carbapenem-resistant and hypervirulent K. pneumoniae (hvCRKP) strains are increasingly reported worldwide and have been found to belong to a variety of sequence types (STs). In this study, we report and characterized an hvCRKP strain of ST592, an uncommon ST, which caused a fatal infection in intensive care unit (ICU) in China and represents a novel type of hvCRKP. We demonstrated that this novel hvCRKP type emerged from the carbapenem-susceptible hypervirulent K. pneumoniae (hvKP) lineage of the K57 capsular type. K57 hvKP contains a pLVPK-like virulence plasmid and then acquired a conjugative blaKPC–2-carrying plasmid to form hvCRKP. The pLVPK-like virulence plasmid contains no complete conjugation module but was able to be transferred by fusion with the conjugative blaKPC–2-carrying plasmid during conjugation. This represents a new mechanism of simultaneous transfer genetic determinants of carbapenem resistance and virulence and highlights the undergoing expansion of hvCRKP, which requires rigorous monitoring and novel countermeasures to curb plasmid-mediated transmission.

Abstract
Among non-conventional yeasts of industrial interest, the dimorphic oleaginous yeast Yarrowia lipolytica appears as one of the most attractive for a large range of white biotechnology applications, from heterologous proteins secretion to cell factories process development. The past, present and potential applications of wild-type, traditionally improved or genetically modified Yarrowia lipolytica strains will be resumed, together with the wide array of molecular tools now available to genetically engineer and metabolically remodel this yeast. The present review will also provide a detailed description of Yarrowia lipolytica strains and highlight the natural biodiversity of this yeast, a subject little touched upon in most previous reviews. This work intends to fill this gap by retracing the genealogy of the main Yarrowia lipolytica strains of industrial interest, by illustrating the search for new genetic backgrounds and by providing data about the main publicly available strains in yeast collections worldwide. At last, it will focus on exemplifying how advances in engineering tools can leverage a better biotechnological exploitation of the natural biodiversity of Yarrowia lipolytica and of other yeasts from the Yarrowia clade.

Abstract
Yarrowia lipolytica is a non-conventional, heterothallic, oleaginous yeast with wide range of industrial applications. Increasing ploidy can improve advantageous traits for industrial applications including genetic stability, stress resistance, and productivity, but the construction of knockout mutant strains from polyploid cells requires significant effort due to the increased copy numbers of target genes. The goal of this study was to evaluate the effectiveness of a mating-type switching strategy by single-step transformation without a genetic manipulation vestige, and to optimize the conventional method for increasing ploidy (mating) in Y. lipolytica. In this study, mating-type genes in haploid Y. lipolytica cells were scarlessly converted into the opposite type genes by site-specific homologous recombination, and the resulting MATB-type cells were mated at low temperature (22°C) with addition of sodium citrate with each MATA-type haploid cell to yield a MATA/MATB-type diploid strain with genetic information from both parental strains. The results of this study can be used to increase ploidy and for whole genome engineering of a yeast strain with unparalleled versatility for industrial application.

Abstract
Yeast whole genome sequencing (WGS) lacks end-to-end workflows that identify genetic engineering. Here we present Prymetime, a tool that assembles yeast plasmids and chromosomes and annotates genetic engineering sequences. It is a hybrid workflow-it uses short and long reads as inputs to perform separate linear and circular assembly steps. This structure is necessary to accurately resolve genetic engineering sequences in plasmids and the genome. We show this by assembling diverse engineered yeasts, in some cases revealing unintended deletions and integrations. Furthermore, the resulting whole genomes are high quality, although the underlying assembly software does not consistently resolve highly repetitive genome features. Finally, we assemble plasmids and genome integrations from metagenomic sequencing, even with 1 engineered cell in 1000. This work is a blueprint for building WGS workflows and establishes WGS-based identification of yeast genetic engineering.

Abstract
Yarrowia lipolytica has been extensively used to produce essential chemicals and enzymes. As in most other eukaryotes, nonhomologous end joining (NHEJ) is the major repair pathway for DNA double-strand breaks in Y. lipolytica Although numerous studies have attempted to achieve targeted genome integration through homologous recombination (HR), this process requires the construction of homologous arms, which is time-consuming. This study aimed to develop a homology-independent and CRISPR/Cas9-mediated targeted genome integration tool in Y. lipolytica Through optimization of the cleavage efficiency of Cas9, targeted integration of a hyg fragment was achieved with 12.9% efficiency, which was further improved by manipulation of the fidelity of NHEJ repair, the cell cycle, and the integration sites. Thus, the targeted integration rate reached 55% through G1 phase synchronization. This tool was successfully applied for the rapid verification of intronic promoters and iterative integration of four genes in the pathway for canthaxanthin biosynthesis. This homology-independent integration tool does not require homologous templates and selection markers and achieves one-step targeted genome integration of the 8,417-bp DNA fragment, potentially replacing current HR-dependent genome-editing methods for Y. lipolytica IMPORTANCE This study describes the development and optimization of a homology-independent targeted genome integration tool mediated by CRISPR/Cas9 in Yarrowia lipolytica This tool does not require the construction of homologous templates and can be used to rapidly verify genetic elements and to iteratively integrate multiple-gene pathways in Y. lipolytica This tool may serve as a potential supplement to current HR-dependent genome-editing methods for eukaryotes.

Abstract
Filamentous fungi have several industrial, environmental, and medical applications. However, they are rarely utilized owing to the limited availability of full-genome sequences and genetic manipulation tools. Since the recent discovery of the full-genome sequences for certain industrially important filamentous fungi, CRISPR/Cas9 technology has drawn attention for the efficient development of engineered strains of filamentous fungi. CRISPR/Cas9 genome editing has been successfully applied to diverse filamentous fungi. In this review, we briefly discuss the use of common genetic transformation techniques as well as CRISPR/Cas9-based systems in filamentous fungi. Furthermore, we describe potential limitations and challenges in the practical application of genome engineering of filamentous fungi. Finally, we provide suggestions and highlight future research prospects in the area.

Abstract
The oleaginous non-conventional yeast Yarrowia lipolytica has enormous potential as a microbial platform for the synthesis of various bioproducts. However, while the model yeast Saccharomyces cerevisiae has very high homologous recombination (HR) efficiency, non-homologous end-joining is dominant in Y. lipolytica, and foreign genes are randomly inserted into the genome. Consequently, the low HR efficiency greatly restricts the genetic engineering of this yeast. In this study, RAD52, the key component of the HR machinery in S. cerevisiae, was grafted into Y. lipolytica to improve HR efficiency. The gene ade2, whose deletion can result in a brown colony phenotype, was used as the reporter gene for evaluating the HR efficiency. The HR efficiency of Y. lipolytica strains before and after integrating the ScRad52 gene was compared using insets with homology arms of different length. The results showed that the strategy could achieve gene targeting efficiencies of up to 95% with a homology arm length of 1000 bp, which was 6.5 times of the wildtype strain and 1.6 times of the traditionally used ku70 disruption strategy. This study will facilitate the further genetic engineering of Y. lipolytica to make it a more efficient cell factory for the production of value-added compounds. The gene ade2 was chose as the reporter gene for evaluating the HR efficiency. RAD52 governing the HR machinery in S. cerevisiae was grafted into Y. lipolytica. RAD52 could improve the HR efficiency of Y. lipolytica. It was better than the traditionally used ku70 disruption strategy.

Edwards H, Yang Z, Xu P. Characterization of Met25 as a color associated genetic marker in Yarrowia lipolytica. Metab Eng Commun 2020; 11:e00147. [PMID: 33083227 PMCID: PMC7554020 DOI: 10.1016/j.mec.2020.e00147] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 09/27/2020] [Accepted: 09/28/2020] [Indexed: 12/14/2022] Open
Abstract
Yarrowia lipolytica offers an ideal host for biosynthesis of high value natural products and oleochemicals through metabolic engineering despite being restricted to a limited number of selective markers, and counter-selection achieved primarily with URA3. In this work, we investigate MET25, a locus encoding sulfide housekeeping gene within the cell, to be exploited as a standard genetic marker. Divalent lead supplemented in media induces lead sulfide (PbS) aggregation in MET25-deficient cells such that deficient cells grow brown/black, and cells with functional copies of MET25 grow white. Loss of MET25 did not induce strict auxotrophic requirements for methionine in Y. lipolytica, indicating MET25 deficiency could be rescued by alternative pathways. Plasmid and chromosomal-based complementation of MET25 in the met25 deficient cells on a double layer agar plate with nutrient gradients demonstrates delayed phenotype (white morphology) restoration, indicating post-transcriptional feedback regulation of methionine biosynthesis in this yeast. MET25 deficient Y. lipolytica could be used as an efficient whole-cell lead sensor with detection limit as low as 10 ppm of lead in drinking water. We further tested whether MET25 deficiency can be exploited to confer resistance to methyl-mercury through chemical neutralization and detoxification. Kinetic growth curves of wild type and MET25-deficient cells were obtained under varying concentrations of methylmercury and cellular toxicity to methyl mercury was calculated from the Hill equation. Our results indicate that methylmecury may not be used as the counter-selectable marker due to insignificant changes of growth fitness. This work demonstrates the utility of using MET25 as a sensitive lead sensor and the challenges of using MET25 as a counter-selectable genetic marker, as well as the complex regulation of methionine biosynthesis in Y. lipolyitca, which may shed lights for us to develop valuable biotechnological applications centering around the sulfur house-keeping metabolism of the nonconventional yeast. Sulfur house-keeping gene MET25 was characterized as a standard genetic marker in Y. lipolytica. MET25 deficiency leads to visual phenotypic change of yeast colony with brown/black pigmentation. Delayed phenotype restoration indicates post-transcriptional feedback regulation of methionine biosynthesis. MET25 deficiency was exploited as a sensitive whole-cell sensor to detect lead in drinking water. MET25 may not be used as the counter-selectable marker due to insignificant changes of growth fitness when the cell is challenged with methylmercury.

Abstract
The DO-stat fed-batch fermentation was carried out to explore the volumetric productivity of β-carotene in engineered Yarrowia lipolytica C11 strain. Using DO-stat fed-batch fermentation, we achieved 94 g/L biomass and 2.01 g/L β-carotene. Both biomass and β-carotene were about 1.28-fold higher than that in fed-batch fermentation. The ATP, NADP+/NADPH, and gene expression levels of tHMG, GGS1, carRA, and carB were promoted as compared to that in fed-batch fermentation. As for as the kinetic parameters in DO-stat fed-batch fermentation, μm', Yx/s', and Yp/s' was 0.527, 0.353, and 0.158, respectively. The μm' was elevated 4.66-fold than that in fed-batch fermentation. These data illustrate that more dissolved oxygen increased the biomass. The Yx/s' and Yp/s' were increased 1.15 and 22.57-fold, which suggest that the DO-stat fed-batch fermentation reduced the Crabtree effect and improved the utilization rate of glucose. Therefore, DO-stat fed-batch fermentation is a promising strategy in the industrialized production of β-carotene.

Abstract
Microbial production of chemical compounds often requires highly engineered microbial cell factories. During the last years, CRISPR-Cas nucleases have been repurposed as powerful tools for genome editing. Here, we briefly review the most frequently used CRISPR-Cas tools and describe some of their applications. We describe the progress made with respect to CRISPR-based multiplex genome editing of industrial bacteria and eukaryotic microorganisms. We also review the state of the art in terms of gene expression regulation using CRISPRi and CRISPRa. Finally, we summarize the pillars for efficient multiplexed genome editing and present our view on future developments and applications of CRISPR-Cas tools for multiplex genome editing.

An artificial chromosome ylAC enables efficient assembly of multiple genes in Yarrowia lipolytica for biomanufacturing. Commun Biol 2020; 3:199.

Abstract
The efficient use of the yeast Yarrowia lipolytica as a cell factory is hampered by the lack of powerful genetic engineering tools dedicated for the assembly of large DNA fragments and the robust expression of multiple genes. Here we describe the design and construction of artificial chromosomes (ylAC) that allow easy and efficient assembly of genes and chromosomal elements. We show that metabolic pathways can be rapidly constructed by various assembly of multiple genes in vivo into a complete, independent and linear supplementary chromosome with a yield over 90%. Additionally, our results reveal that ylAC can be genetically maintained over multiple generations either under selective conditions or, without selective pressure, using an essential gene as the selection marker. Overall, the ylACs reported herein are game-changing technology for Y. lipolytica, opening myriad possibilities, including enzyme screening, genome studies and the use of this yeast as a previous unutilized bio-manufacturing platform. Zhong-peng Guo et al. develop artificial chromosomes (ylAC) that allow easy and efficient assembly of multiple genes in Yarrowia lipolytica, a yeast strain commonly used for synthetic biology. ylAC provides an improved bio-manufacturing platform that is potentially useful for food, pharmaceutical, and environmental industries.

CRISPR-Cas12a/Cpf1-assisted precise, efficient and multiplexed genome-editing in Yarrowia lipolytica. Metab Eng Commun 2019; 10:e00112.

Abstract
CRISPR-Cas9 has been widely adopted as the basic toolkit for precise genome-editing and engineering in various organisms. Alternative to Cas9, Cas12 or Cpf1 uses a simple crRNA as a guide and expands the protospacer adjacent motif (PAM) sequence to TTTN. This unique PAM sequence of Cpf1 may significantly increase the on-target editing efficiency due to lower chance of Cpf1 misreading the PAMs on a high GC genome. To demonstrate the utility of CRISPR-Cpf1, we have optimized the CRISPR-Cpf1 system and achieved high-editing efficiency for two counter-selectable markers in the industrially-relevant oleaginous yeast Yarrowia lipolytica: arginine permease (93% for CAN1) and orotidine 5′-phosphate decarboxylase (~96% for URA3). Both mutations were validated by indel mutation sequencing. For the first time, we further expanded this toolkit to edit three sulfur house-keeping genetic markers (40%–75% for MET2, MET6 and MET25), which confers yeast distinct colony color changes due to the formation of PbS (lead sulfide) precipitates. Different from Cas9, we demonstrated that the crRNA transcribed from a standard type II RNA promoter was sufficient to guide Cpf1 endonuclease activity. Furthermore, modification of the crRNA with 3′ polyUs facilitates the faster maturation and folding of crRNA and improve the genome editing efficiency. We also achieved multiplexed genome editing, and the editing efficiency reached 75%–83% for duplex genomic targets (CAN1-URA3 and CAN1-MET25) and 41.7% for triplex genomic targets (CAN1-URA3-MET25). Taken together, this work expands the genome-editing toolbox for oleaginous yeast species and may accelerate our ability to engineer oleaginous yeast for both biotechnological and biomedical applications. Cpf1 expands the PAM to TTTN and increases the on-target editing efficiency. CRISPR-Cpf1 is optimized to edit genetic markers CAN1, URA3, MET2, MET6 and MET25. A type II RNA promoter was sufficient to guide Cpf1 endonuclease activity. CrRNA modified with 3′ polyUs improves the on-target genome editing efficiency. Duplex genome-editing reaches 75%–83% and triplex editing reaches 42% in Y. lipolytica.

A set of plasmids carrying antibiotic resistance markers and Cre recombinase for genetic engineering of nonconventional yeast Zygosaccharomyces rouxii. Yeast 2019; 36:711-722.

Abstract
The so-called nonconventional yeasts are becoming increasingly attractive in food and industrial biotechnology. Among them, Zygosaccharomyces rouxii is known to be halotolerant, osmotolerant, petite negative, and poorly Crabtree positive. These traits and the high fermentative vigour make this species very appealing for industrial and food applications. Nevertheless, the biotechnological exploitation of Z. rouxii has been biased by the low availability of genetic engineering tools and the recalcitrance of this yeast towards the most conventional transformation procedures. Centromeric and episomal Z. rouxii plasmids have been successfully constructed with prototrophic markers, which limited their usage to auxotrophic strains, mainly derived from the Z. rouxii haploid type strain Centraalbureau voor Schimmelcultures (CBS) 732T . By contrast, the majority of industrially promising Z. rouxii yeasts are prototrophic and allodiploid/aneuploid strains. In order to expand the genetic tools for manipulating these strains, we developed two centromeric and two episomal vectors harbouring KanMXR and ClonNATR as dominant drug resistance markers, respectively. We also constructed the plasmid pGRCRE that allows the Cre recombinase-mediated marker recycling during multiple gene deletions. As proof of concept, pGRCRE was successfully used to rescue the kanMX-loxP module in Z. rouxii ATCC 42981 G418-resistant mutants previously constructed by replacing the MATαP expression locus with the loxP-kanMX-loxP cassette.

Abstract
The oleaginous yeast Yarrowia lipolytica is widely used for the production of both bulk and fine chemicals, including organic acids, fatty acid-derived biofuels and chemicals, polyunsaturated fatty acids, single-cell proteins, terpenoids, and other valuable products. Consequently, it is becoming increasingly popular for metabolic engineering applications. Multiple gene manipulation tools including URA blast, Cre/LoxP, and transcription activator-like effector nucleases (TALENs) have been developed for metabolic engineering in Y. lipolytica. However, the low efficiency and time-consuming procedures involved in these methods hamper further research. The emergence of the CRISPR/Cas system offers a potential solution for these problems due to its high efficiency, ease of operation, and time savings, which can significantly accelerate the genomic engineering of Y. lipolytica. In this review, we summarize the research progress on the development of CRISPR/Cas systems for Y. lipolytica, including Cas9 proteins and sgRNA expression strategies, as well as gene knock-out/knock-in and repression/activation applications. Finally, the most promising and tantalizing future prospects in this area are highlighted.
