BRC Science Highlight Developmental regulation of processes, pathways, and genes that affect stem growth and composition in sorghum Objective Obtain information on the regulation of processes, pathways, and genes that affect stem growth, biomass accumulation, sucrose accumulation, and cell wall biogenesis useful for optimizing energy sorghum biomass composition Approach Characterize the developmental time course of Della, an energy sorghum that accumulates high levels of stem sugars, for: Biomass accumulation and partitioning among organs Total stem composition Non-structural carbohydrate accumulation in stems Stem RNA-seq transcriptome profiles Notes: text Title again: Text 1-2 sentence summary? Result/Impacts Determined sorghum developmental dynamics and correlations for biomass partitioning, stem gene expression, cell wall biosynthesis, and sucrose accumulation. This resource, of more than 200 genes involved in sorghum stem cell wall biology and sugar accumulation, will be useful for future engineering of sorghum to improve conversion to biofuels and bio-products.
