图5 干旱胁迫后马铃薯叶片中差异基因表达量火山图 横坐标代表基因在不同样品中表达倍数变化; 纵坐标代表基因表达量变化的统计学显著程度。图中每个基因均由一个点表示, 黑色圆点表示无显著性差异的基因, 左侧绿色圆点表示有显著性差异的下调基因, 右侧红色圆点表示有显著性差异的上调基因。

Fig. 5 Volcano plot of gene expression in potato leaves after drought stress The abscissa shows the log2 (fold change) between the two samples; the ordinate shows the statically significance of the difference. Each gene is represented by one point on the graph. Differential genes with no significant difference were represented by black dots, those left green points and right red points represent significantly different down-regulated and up-regulated genes, respectively.
