Abstract
Water scarcity is a significant constraint on agricultural practices, particularly in Colombia, where numerous palm cultivators rely on rainfed systems for their plantations. Identifying drought-tolerant cultivars becomes pivotal to mitigating the detrimental impacts of water stress on growth and productivity. This study scrutinizes the variability in drought responses of growth, physiological, and biochemical variables integral to selecting drought-tolerant oil palm cultivars in the nursery. A comprehensive dataset was compiled by subjecting seedlings of eleven cultivars to four soil water potentials (-0.05 MPa, -0.5 MPa, -1 MPa, and -2 MPa) over 60 days. This dataset encompasses growth attributes, photosynthetic parameters like maximum quantum yield and electron transfer rate, gas exchange (photosynthesis, transpiration, and water use efficiency), levels of osmolytes (proline and sugars), abscisic acid (ABA) content, as well as antioxidant-related enzymes, including peroxidase, catalase, ascorbate peroxidase, glutathione reductase, and superoxide dismutase. Principal Component Analysis (PCA) elucidated two principal components that account for approximately 65% of the cumulative variance. Noteworthy enzyme activity was detected for glutathione reductase and ascorbate peroxidase. When juxtaposed with the other evaluated cultivars, one of the cultivars (IRHO 7001) exhibited the most robust response to water deficit. The six characteristics evaluated (photosynthesis, predawn water potential, proline, transpiration, catalase activity, sugars) were determined to be the most discriminant when selecting palm oil cultivars with tolerance to water deficit.

Abstract
The CRISPR/Cas9 genome editing system has been in the spotlight compared to programmable nucleases such as ZFNs and TALENs due to its simplicity, versatility, and high efficiency. CRISPR/Cas9 has revolutionized plant genetic engineering and is broadly used to edit various plants' genomes, including those transformation-recalcitrant species such as oil palm. This review will comprehensively present the CRISPR-Cas9 system's brief history and underlying mechanisms. We then highlighted the establishment of the CRISPR/Cas9 system in plants with an emphasis on the strategies of highly efficient guide RNA design, the establishment of various CRISPR/Cas9 vector systems, approaches of multiplex editing, methods of transformation for stable and transient techniques, available methods for detecting and analyzing mutations, which have been applied and could be adopted for CRISPR/Cas9 genome editing in oil palm. In addition, we also provide insight into the strategy of DNA-free genome editing and its potential application in oil palm.

Functional characterization of the MSP-C6 promoter as a potential tool for mesocarp-preferential expression of transgenes. JOURNAL OF PLANT PHYSIOLOGY 2023; 289:154080.

Abstract
Modification of lipid composition in the mesocarp tissue of oil palm involves genetic manipulation of multiple genes. More than one mesocarp-preferential promoter is necessary for the expression of individual transgenes in the same plant to obviate transcriptional gene silencing. This study aimed to identify genes that are preferentially expressed in the mesocarp tissue and characterize selected candidate mesocarp-preferential promoters. Ten transcripts that were preferentially expressed in the mesocarp tissue were identified from the analysis of 82 transcriptome datasets of 12 different oil palm tissues. The expression of two candidate genes, MSP-C1 and MSP-C6, was verified to be preferentially expressed in the mesocarp tissues and shown to have a low expression level in non-mesocarp tissues by reverse transcription quantitative real-time PCR (RT-qPCR). MSP-C6 promoter fragments of different lengths were transformed into tomato plants for further characterization. Both unripe and ripe fruits of transgenic tomato plants transformed with a construct harboring the MSP-C6-F1 (2014 bp) promoter were shown to have high beta-glucuronidase (GUS) activities. The findings of this study suggest the potential applications of the MSP-C6 promoter as a molecular tool for genetic engineering of novel traits in fruit crops.

Abstract
Abstract
In recent years, research on the epoxidation of fatty acids has attracted a great deal of attention due to the increased need for eco-friendly epoxides generated from vegetable oils. The purpose of this research is to produce bio-lubricant from optimized epoxidized oleic acid by alcoholysis with methanol, tert-butyl alcohol, and ethanolamine. Epoxidation is carried out using in situ performic acid formation under a constant temperature of 60 °C where formic acid acts as an oxygen carrier and hydrogen peroxide acts as an oxygen donor. The determination of the optimum process parameters uses one factor at a time (OFAT) method and is based on the optimized process parameters until the maximum relative conversion to oxirane of 65% is achieved. The bio-lubricants are confirmed using the Fourier Transform Infrared (FTIR) analysis and the results show that the hydroxyl group is present at 3400 cm−1 of wavenumber. A kinetic modeling is performed using the MATLAB optimization tool. After 100 iterations, the reaction rate constant based on optimized epoxidized dated palm oil production were obtained as follows: k
11 = 0.4251 mol⋅L−1⋅min−1, k
12 = 11.345 mol⋅L−1⋅min−1, and k
2 = 0.6761 mol⋅L−1⋅min−1.

Abstract
BACKGROUND Oil palm is the most efficient oil-producing crop in the world, and the yield of palm oil is associated with embryonic development. However, a comprehensive understanding of zygotic embryo development at the molecular level remains elusive. In order to address this issue, we report the transcriptomic analysis of zygotic embryo development in oil palm, specifically focusing on regulatory genes involved in important biological pathways. RESULTS In this study, three cDNA libraries were prepared from embryos at S1 (early-stage), S2 (middle-stage), and S3 (late-stage). There were 16,367, 16,500, and 18,012 genes characterized at the S1, S2, and S3 stages of embryonic development, respectively. A total of 1522, 2698, and 142 genes were differentially expressed in S1 vs S2, S1 vs S3, and S2 vs S3, respectively. Using Gene Ontology (GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis to identify key genes and pathways. In the hormone signaling pathway, genes related to auxin antagonize the output of cytokinin which regulates the development of embryo meristem. The genes related to abscisic acid negatively regulating the synthesis of gibberellin were strongly up-regulated in the mid-late stage of embryonic development. The results were reported the early synthesis and mid-late degradation of sucrose, as well as the activation of the continuous degradation pathway of temporary starch, providing the nutrients needed for differentiation of the embryonic cell. Moreover, the transcripts of genes involved in fatty acid synthesis were also abundantly accumulated in the zygotic embryos. CONCLUSION Taken together, our research provides a new perspective on the developmental and metabolic regulation of zygotic embryo development at the transcriptional level in oil palm.

Abstract
The protocol outlined in this chapter describes a detailed procedure for protoplast isolation and transformation using polyethylene glycol (PEG)-mediated transfection and DNA microinjection, highlighting also the critical steps associated with the method. Briefly, we will describe the efficient isolation of protoplasts from 3-month-old suspension calli collected at 14 days after cultured. Digestion of the calli with an optimal composition of enzyme solution yielded over 2 × 106 protoplasts/mL with the viability of more than 80%. The concentrations of DNA, PEG, and magnesium chloride and application of heat shock treatment are the crucial determinants for efficient PEG-mediated transfection. Using the optimal PEG transfection conditions, a transfection efficiency of more than 20% could be obtained. At the same time, protoplasts embedded in alginate layer cultured for 3 days and injected with 100 ng/μL of total DNA solution are the optimal factors for microinjection. We successfully regenerated the injected protoplasts to calli expressing green fluorescent protein (GFP) signals when cultured in optimal medium and cultivation procedures.

Abstract
Woody plant species represent an invaluable reserve of biochemical diversity to which metabolic engineering can be applied to satisfy the need for commodity and specialty chemicals, pharmaceuticals, and renewable energy. Woody plants are particularly promising for this application due to their low input needs, high biomass, and immeasurable ecosystem services. However, existing challenges have hindered their widespread adoption in metabolic engineering efforts, such as long generation times, large and highly heterozygous genomes, and difficulties in transformation and regeneration. Recent advances in omics approaches, systems biology modeling, and plant transformation and regeneration methods provide effective approaches in overcoming these outstanding challenges. Promises brought by developments in this space are steadily opening the door to widespread metabolic engineering of woody plants to meet the global need for a wide range of sustainably sourced chemicals and materials.

Abstract
Background Genome editing employing the CRISPR/Cas9 system has been widely used and has become a promising tool for plant gene functional studies and crop improvement. However, most of the applied CRISPR/Cas9 systems targeting one locus using a sgRNA resulted in low genome editing efficiency. Results Here, we demonstrate the modification of the FAD2 gene in rice using a multiplex sgRNA-CRISPR/Cas9 genome editing system. To test the system’s efficiency for targeting multiple loci in rice, we designed two sgRNAs based on FAD2 gene sequence of the Oryza sativa Japonica rice. We then inserted the validated sgRNAs into a CRISPR/Cas9 basic vector to construct pYLCRISPRCas9PUbi-H:OsFAD2. The vector was then transformed into protoplast cells isolated from rice leaf tissue via PEG-mediated transfection, and rice calli using biolistic transformation. Direct DNA sequencing of PCR products revealed mutations consisting of deletions of the DNA region between the two target sgRNAs. Conclusion The results suggested that the application of the multiplex sgRNA-CRISPR/Cas9 genome editing system may be useful for crop improvement in monocot species that are recalcitrant to genetic modification, such as oil palm.

Abstract
Cetyltrimethylammonium bromide (CTAB) is the preferred detergent in RNA extraction of oil palm tissues. However, the CTAB-based protocol is time-consuming. In this study, a combination of the CTAB-based method and silica-based purification reduced the extraction time from two days to five hours. Quality of total RNA from 27 different tissues of oil palm was shown to have an RNA integrity number (RIN) value of more than seven. The extracted RNA was evaluated by RT-qPCR using three reference oil palm genes (GRAS, CYP2, and SLU7) and three putative mesocarp-specific transcripts annotated as WRKY DNA-binding protein 70 (WRKY-70), metallothionein (MT) and pentatricopeptide repeat (PPR) genes. Tissue-specific expression profiling across complete developmental stages of mesocarp and vegetative tissues was determined in this study. Overall, the RNA extraction protocol described here is rapid, simple and yields good quality RNAs from oil palm tissues.

Abstract
The improvement of the yield and quality of oil palm via precise genome editing has been indispensable goal for oil palm breeders. Genome editing via the CRISPR/Cas9 (CRISPR-associated protein 9) system, ZFN (zinc finger nucleases) and TALEN (transcription activator-like effector nucleases) has flourished as an efficient technology for precise target modifications in the genomes of various crops. Among the genome editing technologies, base editing approach has emerged as novel technology that could generate single base changes i.e. irreversible conversion of one target base in to other in a programmable manner. A base editor (adenine or cytosine) is a fusion of catalytically inactive CRISPR-Cas9 domain (Cas9 variants) and cytosine or adenosine deaminase domain that introduces desired point mutations. However, till date no such genetic modifications have ever been developed in oil palm via base editing technology. Precise genome editing via base editing approach can be a challenging task in oil palm due to its complex genome as well as difficulties in tissue culture and genetic transformation methods. However, availability of whole genome sequencing data in oil palm provides a platform for developing the base editing technology. Here, we briefly review the potential application and future implications of base editing technology for the genetic improvement of oil palm.

Abstract
The biodiesel from lignocellulosic materials has been widely recognized as an alternative fuel to meet energy requirements worldwide, facing fossil fuel depletion, and emerging energy policies. In this work, the biorefinery approach was applied for biodiesel production from jatropha and palm oils in order to make it economically competitive by the utilization of residual biomass as the feedstock for obtaining hydrogen via steam reforming of glycerol and gasification. The linear chains for hydrogen and diesel were simulated using UniSim software and main stream properties were collected from the literature or predicted by correlations. The proposed scheme of biorefinery was analyzed through environmental and techno-economic assessment to identify the feasibility of this process to be implemented. Three different blends of oils (JO10-PO90, JO20-PO80, and JO30-PO70) were considered in the environmental analysis to determine alternatives for reducing potential environmental impacts (PEIs). It was found that the acidification potential highly contributed to the environmental impacts attributed to the use of fossil fuels for heating requirements, and JO30-PO70 blend exhibited the lowest PEI value. The economic indicators were calculated to be 8,455,147.29 $USD and 33.18% for the net present value and internal rate of return, respectively. These results revealed that the proposed combined biomass biorefinery is feasible to be scaled up without causing significant negative impacts on the environment.

Abstract
Oil palm (Elaeis guineensis, Jacq.) is a prominent vegetable-oil-yielding crop. Cultivating high-yielding oil palm with improved traits is a pre-requisite to meet the increasing demands of palm oil consumption. However, tissue culture and biotechnological approaches can resolve these concerns. Over the past three decades, significant research has been carried out to develop tissue culture and genetic transformation protocols for oil palm. Somatic embryogenesis is an efficient platform for the micropropagation of oil palm on a large scale. In addition, various genetic transformation techniques, including microprojectile bombardment, Agrobacterium tumefaciens mediated, Polyethylene glycol mediated mediated, and DNA microinjection, have been developed by optimizing various parameters for the efficient genetic transformation of oil palm. This review mainly emphasizes the methods established for in vitro propagation and genetic transformation of oil palm. Finally, we propose the application of the genome editing tool CRISPR/Cas9 to improve the various traits in this oil yielding crop.

Brew-Appiah RAT, Peracchi LM, Sanguinet KA. Never the Two Shall Mix: Robust Indel Markers to Ensure the Fidelity of Two Pivotal and Closely-Related Accessions of Brachypodium distachyon. PLANTS 2019; 8:plants8060153. [PMID: 31174296 PMCID: PMC6630600 DOI: 10.3390/plants8060153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/20/2019] [Revised: 05/30/2019] [Accepted: 06/05/2019] [Indexed: 11/25/2022]
Abstract
Brachypodium distachyon is an established model for monocotyledonous plants. Numerous markers intended for gene discovery and population genetics have been designed. However to date, very few indel markers with larger and easily scored length polymorphism differences, that distinguish between the two morphologically similar and highly utilized B. distachyon accessions, Bd21, the reference genome accession, and Bd21-3, the transformation-optimal accession, are publically available. In this study, 22 indel markers were designed and utilized to produce length polymorphism differences of 150 bp or more, for easy discrimination between Bd21 and Bd21-3. When tested on four other B. distachyon accessions, one case of multiallelism was observed. It was also shown that the markers could be used to determine homozygosity and heterozygosity at specific loci in a Bd21 x Bd3-1 F2 population. The work done in this study allows researchers to maintain the fidelity of Bd21 and Bd21-3 stocks for both transgenic and nontransgenic studies. It also provides markers that can be utilized in conjunction with others already available for further research on population genetics, gene discovery and gene characterization, all of which are necessary for the relevance of B. distachyon as a model species.
