Elucidation of the Gene Regulatory Networks Governing Terpenoid-Mediated Plant-Environment Interactions to Enable Advanced Bioenergy Crops

ABSTRACT: The proposed project aims to elucidate the gene-regulatory networks (GRNs) underlying terpenoid metabolism in three major bioenergy crops, switchgrass (Panicum virgatum), maize (Zea mays), and sorghum (Sorghum bicolor), to aid crop development for enhanced stress resilience and biofuel production from biomass feedstock. Prior studies identified more than 50 terpene synthases (TPS) and cytochrome P450 monooxygenases (P450), as key enzymes in generating bioactive terpenoids, in several bioenergy plants including switchgrass and maize. This knowledge now enables a precise investigation of the GRNs that govern common and species-specific terpenoid pathways. We will integrate transcription factor (TF) functional studies, TF binding site mapping, transcript and metabolite profiling, and terpenoid pathway engineering to identify the terpenoid-metabolic TF networks mediating stress responses in switchgrass, maize and sorghum. The work (proposal:https://doi.org/10.46936/10.25585/60001378) conducted by the U.S. Department of Energy Joint Genome Institute (https://ror.org/04xm1d337), a DOE Office of Science User Facility, is supported by the Office of Science of the U.S. Department of Energy operated under Contract No. DE-AC02-05CH11231.

Characterization of engineered sorghum with reduced S-adenosyl-L-methionine (AdoMet) levels

Project description:Lignin accumulates progressively in cell walls during plant development, therefore, we are interested in analyzing the transcriptome and metabolome of engineered sorghum lines at three developmental stages. Results from these analyses will help to understand the metabolic changes (if any) besides lignin synthesis in transgenics and anticipate plants' physiological responses during growth under natural environment in future field trials. This project will analyze the transcriptome and metabolome in stems of low-lignin sorghum transgenic lines compared to wild-type (WT) control.

Elucidate metabolism of bioenergy-relevant Clostridial and Streptomyces species

Project description:The goal of this study is to use both "targeted" and "untargeted" metabolomics to elucidate metabolism of Clostrial and Streptomyces species for biofuel production and plant growth promotion, respectively. For these species, we aim to improve the curation of genome-scale metabolic networks and elucidate their novel secondary metabolism to make secondary metabolites whose identities are waiting to be discovered. These metabolic networks will be used to study cell physiology, metabolism, regulation, and metabolic engineering.

Exploring Genetics by Environment - 'omic analysis of engineered biomass crops in the lab and field

Project description:Clonal QSuB switchgrass plants (3 independent transformation events), and their corresponding wild type (var Alamo), grown in a growth chamber and the field, were harvested at two time points (five replicates) during the growing season across two years (2018, 2019), to compare the effects of environment on genetically identical engineered plants. To complement this, we used QsuB plus wild type for Arabidopsis grown in a walk in growth chamber. Three replicates of tissue will be harvested at a single time point. Plants will be well-watered or drought stressed.
