图7 ZmCRY1b和ZmCRY2基因在光周期(长日照和短日照)处理的表达水平 “B73”的幼苗分别在长日照条件下(LD, 16 h光照/8 h黑暗)或短日照条件下(SD, 8 h光照/16 h黑暗)生长13 d后, 每2 h取一次样。把ZmCRY2/Tubulin在黑暗结束时期的比值设为1, 并以此为对照。折线图代表了在3次独立的生物学重复下ZmCRY2/Tubulin的平均值, 其中误差线代表了标准差。

Fig. 7 Relative expression of both ZmCRY1b and ZmCRY2 genes in response to photoperiod (long-day and short-day) treatment The seedlings of maize inbred line B73 were grown in long-day condition (LD, 16 h light/8 h dark) or short-day (SD, 8 h light/16 h dark) for 13 d, then sampled every two hours. The transcription abundance of ZmCRY2 in the dark was set as the control, and the ratio of ZmCRY2/Tubulin at the end of the dark period was set as 1. Each line graph shows the mean expression of ZmCRY2/Tubulin of three biological repeats. Error bars indicate the standard deviation.
