图5 ZmCRY1b和ZmCRY2基因对响应不同光质的相对表达水平分析 玉米自交系“B73”的幼苗在黑暗、持续远红光(FR, 0.25 μmol m-2 s-1)、持续红光(R, 22.3 μmol m-2 s-1)、持续蓝光(B, 13 μmol m-2 s-1)或持续白光(W, 17 μmol m-2 s-1)下生长了13 d。以黑暗条件下的ZmCRY2的转录丰度为对照, 并将该ZmCRY2/Tubulin的比值设为1。柱状图代表了在3次独立的生物学重复下ZmCRY2/Tubulin的平均值, 误差线代表了标准差。用星号表示差异的显著性, * P< 0.05, ** P < 0.01。

Fig. 5 Relative expression analysis of both ZmCRY1b and ZmCRY2 genes under different continuous light conditions The seedlings of maize inbred line B73 were grown in continuous far-red light (FR, 0.25 μmol m-2 s-1), red light (R, 22.3 μmol m-2 s-1), blue light (B, 13 μmol m-2 s-1), or white light (W, 170 μmol m-2 s-1) for 13 d. The transcription abundance of ZmCRY2 in the dark was set as the control, and the ratio of ZmCRY2/Tubulin in the dark was set as 1. Each column shows the mean expression of ZmCRY2/Tubulin of three biological repeats. Error bars indicate the standard deviation. * P < 0.05, ** P < 0.01.
