图2. 海藻糖处理提高干旱胁迫下水稻叶片内PEPC的转录及翻译水平
模拟干旱处理2小时后C₄-PEPC基因的相对表达量(A)、磷酸烯醇式丙酮酸羧化酶(PEPC)活性(B)和Osppc2a基因的相对表达量(C)。缩写同图1。图中数值代表来自3个生物学重复的平均值±标准差(n=6)。不同小写字母的柱值表示差异显著(P<0.05) (Student-Neuman-Keuls)。

Figure 2. Trehalose treatments increase PEPC transcription and translation in rice leaves under drought stress
C₄-PEPC expression (A), phosphoenolpyruvate carboxylase (PEPC) activity (B) and Osppc2a expression (C) after 2 hours of simulated drought treatment. Abbreviations are the same as those given in Figure 1. Values represent means±SD (n=6) from three biological replicates. Bars labeled with different lowercase letters indicate significant differences (P<0.05) (Student-Neuman-Keuls).
