图5 敲除OsDSK2b降低气孔开度 A: 不同开放程度的气孔图。标尺为10 μm; B: 正常条件下和20% PEG-6000处理4 h后, 野生型日本晴和OsDSK2b敲除株系中3种不同开放程度的气孔占比统计图。结果以3个生物学重复的平均值(±标准差)表示, 每个重复至少统计300个以上气孔; C: 野生型日本晴和OsDSK2b敲除株系中气孔密度统计图; D: 野生型日本晴和OsDSK2b敲除株系中气孔大小统计图。结果以3个生物学重复的平均值(±标准差)表示, 每个重复至少统计100个气孔。

Fig. 5 Knocking out OsDSK2b reduces stomatal aperture A: the stomata with different opening degrees. Bar: 10 μm; B: the stomatal proportions of three different degrees of opening on the leaves of wild-type Nipponbare and OsDSK2b knockout plants under normal condition and after 20% PEG-6000 treatment for 4 h. Values are means (± SDs) of three biological replicates, and at least 300 stomata were calculated in each replicate; C: the stomatal density of wild-type Nipponbare and OsDSK2b knockout plants; D: the stomatal size of wild-type Nipponbare and OsDSK2b knockout plants. Values are means (± SDs) of three biological replicates, and at least 100 stomata were calculated in each replicate.
