Figure 4From: Transcriptomic analysis of Sorghum bicolor responding to combined heat and drought stressRelative transcript abundance of genes representative of the gene sets identified as being up-regulated preferentially by either drought stress (a), heat stress (b) or combined heat and drought stress (c). Error bars represent RQMIN and RQMAX and constitute the acceptable error level for a 95% confidence level according to Student’s t-test.Back to article page
