图6 OsDSK2b调控抗逆相关基因的表达 A: 20% PEG-6000处理前(0 h)和处理后(4 h)野生型日本晴和OsDSK2b敲除株系中DREB基因的相对表达量; B: 20% PEG-6000处理前(0 h)和处理后(4 h)野生型日本晴和OsDSK2b敲除株系中ABA信号通路相关基因的相对表达量。数据均为3个生物学重复的平均值(±标准差) (Dunnett’s测验, *: P < 0.05; **: P < 0.01)。

Fig. 6 OsDSK2b regulates the relative expression level of stress-related genes A: the relative expression levels of DREB genes in wild-type Nipponbare and OsDSK2b knockout plants before (0 h) and after (4 h) 20% PEG-6000 treatment; B: the relative expression levels of ABA-related genes in wild-type Nipponbare and OsDSK2b knockout plants before (0 h) and after (4 h) 20% PEG-6000 treatment. Values are means (± SDs) from three biological replicates (Dunnett’s test, *P < 0.05; **P < 0.01).
