图4 ZoWRKY基因对逆境的响应分析 (a) ZoWRKY基因对土壤湿度的响应。(b) ZoWRKY基因对青枯菌侵染的响应。LUN：低土壤湿度（WFPS：10%）,HUN：高土壤湿度（WFPS：40%）,HI：高土壤湿度（WFPS：40%）且感染青枯菌;根据每个ZoWRKY基因的表达水平分组计算log2FC,通过edgeR对2组样本间的差异基因进行识别,阈值为log2FC≥1和FDR < 0.05;色阶标尺从左-1.0到右1.0逐渐增大;右侧红色箭头表示上调表达,绿色箭头表示下调表达

Fig.4 Expression analysis of ZoWRKY gene under stress conditions (a) Gene ZoWRKY responses to soil moistures. (b) Gene ZoWRKY responses to infection of R. solanacearum. LUN: low soil moisture (WFPS: 10%); HUN: high soil moisture (WFPS: 40%); HI: high soil moisture (WFPS: 40%) and infection of R. solanacearum; log2FC value was calculated pairwise based on the expression level for each ZoWRKY gene, DEGs were identified between each two groups by edgeR with thresholds of log2FC ≥1 and FDR < 0.05; color scale increases from left to right with values -1.0 to 1.0; red arrow indicates up-regulated expression, green arrow indicates down-regulated expression
