图4. 海藻糖处理影响干旱胁迫下水稻叶片内海藻糖、SnRKs及ABA相关基因的表达
(A) 海藻糖合成与代谢相关基因的表达; (B) SnRKs相关基因的表达; (C) ABA代谢相关基因的表达。缩写同图1。热图显示基因相对表达量对数转换均一化值, 显著性分析表示基因相对表达量之间的差异(附表1)。图中不同小写字母表示差异显著(P<0.05) (Student-Neuman-Keuls)。

Figure 4. Trehalose treatments affect the expression of trehalose, SnRKs and ABA-related genes in rice leaves under drought stress
(A) The expression of trehalose biosynthesis and metabolism related genes; (B) The expression of SnRKSs-related genes; (C) The expression of ABA metabolism-related genes. Abbreviations are the same as those given in Figure 1. The heat map shows the log-transformed normalized values of relative gene expression, and the significance analysis showed the difference between relative gene expressions (Appendix Table 1). Different lowercase letters indicate significant differences (P<0.05) (Student-Neuman-Keuls).
