Fig. 4From: Global analysis of switchgrass (Panicum virgatum L.) transcriptomes in response to interactive effects of drought and heat stressesHeat map with clusters based on FPKM values for A) DT vs Control, B) DTHT vs control and C) DTHT vs DT TFs. The Heat map shows a grouping of control samples and stress samples. Extended periods of DTHT to stress samples showed abundant up-regulated TFs (A and B) and down-regulated TFs (C) compared to their control samples. For example, there were more responsive TFs which were up-regulated at time 144/72 h compared to its control sample at Control 144/72 h (A)Back to article page
