Figure 1

Effects of drought stress on different foxtail millet genotypes. (A) Drought survival rates of 12 foxtail millet landraces in the drought/rewatering experiment. The phenotypic data were obtained from six replicated experiments, and each experiment contained 15 biological replicates. The experimental procedure follows that of a previous study16. (B) Soil volumetric water content during the 10-day drought treatment. (C) The leaf water potential (LWP) of ‘An04’ plants decreased to approximately onefold lower than that of ‘Yugu1’ after 8 d of drought. The arrow indicates the day on which we sampled the plant materials for RNA-seq. (D) The expression levels of four representative drought-responsive genes from ‘Yugu1’ and ‘An04’ plants were analyzed by qPCR. The four drought-inducible marker genes were a dehydrin (Seita.8G115400), SiDREB2A (Gene ID: Seita.4G016400), SiSIP2 (Seita.2G081000), and SiNCED9 (Seita.9G156500). Error bars represent standard errors of the mean (n = 6). (E) Phenotypic alterations of ‘Yugu1’ and ‘An04’ in response to drought.
