Liu S, Zenda T, Tian Z, Huang Z. Metabolic pathways engineering for drought or/and heat tolerance in cereals. FRONTIERS IN PLANT SCIENCE 2023; 14:1111875.

Abstract
Drought (D) and heat (H) are the two major abiotic stresses hindering cereal crop growth and productivity, either singly or in combination (D/+H), by imposing various negative impacts on plant physiological and biochemical processes. Consequently, this decreases overall cereal crop production and impacts global food availability and human nutrition. To achieve global food and nutrition security vis-a-vis global climate change, deployment of new strategies for enhancing crop D/+H stress tolerance and higher nutritive value in cereals is imperative. This depends on first gaining a mechanistic understanding of the mechanisms underlying D/+H stress response. Meanwhile, functional genomics has revealed several stress-related genes that have been successfully used in target-gene approach to generate stress-tolerant cultivars and sustain crop productivity over the past decades. However, the fast-changing climate, coupled with the complexity and multigenic nature of D/+H tolerance suggest that single-gene/trait targeting may not suffice in improving such traits. Hence, in this review-cum-perspective, we advance that targeted multiple-gene or metabolic pathway manipulation could represent the most effective approach for improving D/+H stress tolerance. First, we highlight the impact of D/+H stress on cereal crops, and the elaborate plant physiological and molecular responses. We then discuss how key primary metabolism- and secondary metabolism-related metabolic pathways, including carbon metabolism, starch metabolism, phenylpropanoid biosynthesis, γ-aminobutyric acid (GABA) biosynthesis, and phytohormone biosynthesis and signaling can be modified using modern molecular biotechnology approaches such as CRISPR-Cas9 system and synthetic biology (Synbio) to enhance D/+H tolerance in cereal crops. Understandably, several bottlenecks hinder metabolic pathway modification, including those related to feedback regulation, gene functional annotation, complex crosstalk between pathways, and metabolomics data and spatiotemporal gene expressions analyses. Nonetheless, recent advances in molecular biotechnology, genome-editing, single-cell metabolomics, and data annotation and analysis approaches, when integrated, offer unprecedented opportunities for pathway engineering for enhancing crop D/+H stress tolerance and improved yield. Especially, Synbio-based strategies will accelerate the development of climate resilient and nutrient-dense cereals, critical for achieving global food security and combating malnutrition.

Abstract
Nitrogen losses in agricultural systems can be reduced through enhanced-efficiency fertilizers (EEFs), which control the physicochemical release from fertilizers and biological nitrogen transformations in soils. The adoption of EEFs by farmers requires evidence of consistent performance across soils, crops and climates, paired with information on the economic advantages. Here we show that the benefits of EEFs due to avoided social costs of nitrogen pollution considerably outweigh their costs-and must be incorporated in fertilizer policies. We outline new approaches to the design of EEFs using enzyme inhibitors with modifiable chemical structures and engineered, biodegradable coatings that respond to plant rhizosphere signalling molecules.

Optogenetic and Chemical Induction Systems for Regulation of Transgene Expression in Plants: Use in Basic and Applied Research. Int J Mol Sci 2022; 23:ijms23031737.

Abstract
Continuous and ubiquitous expression of foreign genes sometimes results in harmful effects on the growth, development and metabolic activities of plants. Tissue-specific promoters help to overcome this disadvantage, but do not allow one to precisely control transgene expression over time. Thus, inducible transgene expression systems have obvious benefits. In plants, transcriptional regulation is usually driven by chemical agents under the control of chemically-inducible promoters. These systems are diverse, but usually contain two elements, the chimeric transcription factor and the reporter gene. The commonly used chemically-induced expression systems are tetracycline-, steroid-, insecticide-, copper-, and ethanol-regulated. Unlike chemical-inducible systems, optogenetic tools enable spatiotemporal, quantitative and reversible control over transgene expression with light, overcoming limitations of chemically-inducible systems. This review updates and summarizes optogenetic and chemical induction methods of transgene expression used in basic plant research and discusses their potential in field applications.

Abstract
Understanding the biological background of strigolactone (SL) structural diversity and the SL signaling pathway at molecular level requires quantitative and sensitive tools that precisely determine SL dynamics. Such biosensors may be also very helpful in screening for SL analogs and mimics with defined biological functions.Recently, the genetically encoded, ratiometric sensor StrigoQuant was developed and allowed the quantification of the activity of a wide concentration range of SLs. StrigoQuant can be used for studies on the biosynthesis, function and signal transduction of this hormone class.Here, we provide a comprehensive protocol for establishing the use of StrigoQuant in Arabidopsis protoplasts. We first describe the generation and transformation of the protoplasts with StrigoQuant and detail the application of the synthetic SL analogue GR24. We then show the recording of the luminescence signal and how the obtained data are processed and used to assess/determine SL perception.

Abstract
The central dogma (CD) of molecular biology is the transfer of genetic information from DNA to RNA to protein. Major CD processes governing genetic flow include the cell cycle, DNA replication, chromosome packaging, epigenetic changes, transcription, posttranscriptional alterations, translation, and posttranslational modifications. The CD processes are tightly regulated in plants to maintain genetic integrity throughout the life cycle and to pass genetic materials to next generation. Engineering of various CD processes involved in gene regulation will accelerate crop improvement to feed the growing world population. CRISPR technology enables programmable editing of CD processes to alter DNA, RNA, or protein, which would have been impossible in the past. Here, an overview of recent advancements in CRISPR tool development and CRISPR-based CD modulations that expedite basic and applied plant research is provided. Furthermore, CRISPR applications in major thriving areas of research, such as gene discovery (allele mining and cryptic gene activation), introgression (de novo domestication and haploid induction), and application of desired traits beneficial to farmers or consumers (biotic/abiotic stress-resilient crops, plant cell factories, and delayed senescence), are described. Finally, the global regulatory policies, challenges, and prospects for CRISPR-mediated crop improvement are discussed.

Abstract
In optogenetics, light-sensitive proteins are specifically expressed in target cells and light is used to precisely control the activity of these proteins at high spatiotemporal resolution. Optogenetics initially used naturally occurring photoreceptors to control neural circuits, but has expanded to include carefully designed and engineered photoreceptors. Several optogenetic constructs are based on plant photoreceptors, but their application to plant systems has been limited. Here, we present perspectives on the development of plant optogenetics, considering different levels of design complexity. We discuss how general principles of light-driven signal transduction can be coupled with approaches for engineering protein folding to develop novel optogenetic tools. Finally, we explore how the use of computation, networks, circular permutation, and directed evolution could enrich optogenetics.

Abstract
The plant hormones brassinosteroids (BRs) modulate plant growth and development. Cysteine (Cys) residues located in the extracellular domain of a protein are of importance for protein structure by forming disulfide bonds. To date, the systematic study of the functional significance of Cys residues in BR-insensitive 1 (BRI1) is still lacking. We used brassinolide-induced exogenous bri1-EMS-Suppressor 1 (BES1) dephosphorylation in Arabidopsis thaliana protoplasts as a readout, took advantage of the dramatic decrease of BRI1 protein levels during protoplast isolation, and of the strong phosphorylation of BES1 by BR-insensitive 2 (BIN2) in protoplasts, and developed a protoplast transient system to identify critical Cys sites in BRI1. Using this system, we identified a set of critical Cys sites in BRI1, as substitution of these Cys residues with alanine residues greatly compromised the function of BRI1. Moreover, we identified two negative regulators of BR signaling, pattern-triggered immunity compromised RLCK1 (PCRK1) and PCRK2, that were previously known to positively regulate innate immunity signaling. This work not only provides insight into the functional importance of critical Cys residues in stabilizing the superhelical conformation of BRI1-leucine-rich-repeat, but also reveals that PCRK1/2 can inversely modulate BR and plant immune signaling pathways.

Abstract
A gene regulatory network (GRN) describes the hierarchical relationship between transcription factors, associated proteins, and their target genes. Studying GRNs allows us to understand how a plant's genotype and environment are integrated to regulate downstream physiological responses. Current efforts in plants have focused on defining the GRNs that regulate functions such as development and stress response and have been performed primarily in genetically tractable model plant species such as Arabidopsis thaliana. Future studies will likely focus on how GRNs function in non-model plants and change over evolutionary time to allow for adaptation to extreme environments. This broader understanding will inform efforts to engineer GRNs to create tailored crop traits.

Abstract
Ubiquitination modulates nearly all aspects of plant life. Here, we reconstituted the Arabidopsis thaliana ubiquitination cascade in Escherichia coli using a synthetic biology approach. In this system, plant proteins are expressed and then immediately participate in ubiquitination reactions within E. coli cells. Additionally, the purification of individual ubiquitination components prior to setting up the ubiquitination reactions is omitted. To establish the reconstituted system, we co-expressed Arabidopsis ubiquitin (Ub) and ubiquitination substrates with E1, E2 and E3 enzymes in E. coli using the Duet expression vectors. The functionality of the system was evaluated by examining the auto-ubiquitination of a RING (really interesting new gene)-type E3 ligase AIP2 and the ubiquitination of its substrate ABI3. Our results demonstrated the fidelity and specificity of this system. In addition, we applied this system to assess a subset of Arabidopsis E2s in Ub chain formation using E2 conjugation assays. Affinity-tagged Ub allowed efficient purification of Ub conjugates in milligram quantities. Consistent with previous reports, distinct roles of various E2s in Ub chain assembly were also observed in this bacterial system. Therefore, this reconstituted system has multiple advantages, and it can be used to screen for targets of E3 ligases or to study plant ubiquitination in detail.

Abstract
Plant hormones regulate physiological responses in plants, including responses to pathogens and beneficial microbes. The last decades have provided a vast amount of evidence about the contribution of different plant hormones to plant immunity, and also of how they cooperate to orchestrate immunity activation, in a process known as hormone crosstalk. In this review we highlight the complexity of hormonal crosstalk in immunity and approaches currently being used to further understand this process, as well as perspectives to engineer hormone crosstalk for enhanced pathogen resistance and overall plant fitness.

Abstract
With the need to respond to and integrate a multitude of external and internal stimuli, plant signaling is highly complex, exhibiting signaling component redundancy and high interconnectedness between individual pathways. We review here novel theoretical-experimental approaches in manipulating plant signaling towards the goal of a comprehensive understanding and targeted quantitative control of plant processes. We highlight approaches taken in the field of synthetic biology used in other systems and discuss their applicability in plants. Finally, we introduce existing tools for the quantitative analysis and monitoring of plant signaling and the integration of experimentally obtained quantitative data into mathematical models. Incorporating principles of synthetic biology into plant sciences more widely will lead this field forward in both fundamental and applied research.
