Blue and red colour in the heatmap indicates the expression of DEGs is low and high, respectively. (B) DGEs expression pattern in ABA signaling pathway.

Full-size DOI: 10.7717/peerj.11044/fig-DEGs among CK and 20 PEG-6000 therapy groupThere had been 1084 and 603 up- and down-regulated DEGs found involving CK and 20 PEG6000 group. So that you can improved understand the function of DEGs, we performed GO and KEGG evaluation. The GO final results showed that “regulation of catalytic activity”, “regulation of peptidase activity”, “oxidation eduction process”, “plant-type cell wall loosening” and “cell redox homeostasis” have been the primary BP terms respond to drought strain. In which, AfSOD, AfHSP70, AfCYPs, AfCSY4 and 60S ribosomal proteins had higher frequency. The majority of these DEGs have been up-regulated (Fig. 4A). As for KEGG evaluation, DEGs have been considerably enriched in starch and sucrose metabolism, carbon fixation in photosynthetic organisms and 2-Oxocarboxylic acid metabolism pathway. Also, 34 DEGs, such as c144508.graph_c0, c164358.graph_c0, c167827.graph_c0, c171717.graph_c1 and c187107.graph_c0, were enriched in plant hormone signal transduction pathway, although the p worth 0.05. DEGs in plant hormone signal transduction showed that DEGs of salicylic acid downstream were active and transcripts of PP2C were upregulated. Expression of DEGs in ABA and salicylic acid pathway have been shown in Figs. 4B and 4C. What more, DEGs in Starch and sucrose metabolism such as AfTPS, AfTREH, AfAMY, etc. Most DEGs in Carbon fixation in photosynthetic organisms pathway were up regulated.Interaction network of DEGs and proteinsThe interaction network was drawn in line with STRING TLR7 Biological Activity database. There had been 262 up-regulated DEGs with Confidence Score 0.9 as well as the interaction network showed that c160801.graph_c0, c192497.graph_c0, c190485.graph_c1, c175551.graph_c1 have been the core regulators in these DEGs (Fig. 5A). The expression heatmap showed the distinct gene expression pattern involving CK and PEG-6000 therapy group (Fig. 5B). TheSun et al.
