GNPS - Epigenetic Control of Drought Acclimation in Sorghum (EPICON)

ABSTRACT: Two cultivars of sorghum were examined from a study performed at the Kearney Research Station in California; 1) a pre-flowering drought tolerant, post-flowering drought susceptible cultivar RTx430 and 2) a pre-flowering drought susceptible, post-flowering drought-tolerant cultivar BTx642. These data are the methanol/water metabolite fraction obtained from a Folsh extraction from Sorghum bicolor leaves and roots. The metabolites were derivatized and analyzed via GC-MS at PNNL. Analyses represent the metabolite profile collected at 2, 3, 4, 6, 8, 9, 10, 11, 13, 15, 17 weeks post soil emergence and under a perturbation of either well-watered (control), pre-flowering drought, or post-flowering drought.

Drought stress is a major obstacle to crop productivity, and the severity and frequency of drought are expected to increase in the coming century. Certain root-associated bacteria have been shown to mitigate the negative effects of drought stress on plant growth, and manipulation of the crop microbiome is an emerging strategy for overcoming drought stress in agricultural systems, yet the effect of drought on the development of the root microbiome is poorly understood. Through 16S rRNA amplicon a  ...[more]
