摘　要：

整合微阵列数据和采用实时荧光定量PCR 分析拟南芥锌指蛋白DBB 亚家族中8 个基因在不同光周期和不同光质条件下转录表达的结果表明, 在长日和短日照条件下该家族中6 个基因的转录都具有光周期节律性, 并且其中4 个基因的表达受光诱导, 有 1 个基因的表达受光抑制, 1 个基因的表达不受光调节。

Abstract:

The transcripts expression of eight members of DBB (double B-box) subfamily in Arabidopsis under different photoperiods or light quality conditions were investigated using microarray and real-time quantitative PCR. The results showed that the transcription of six members of DBB genes were under the control of circadian clock: four of them were up-regulated, one was down-regulated and one wasn’t regulated in responsed to light.

Key words: Arabidopsis thaliana; photoperiod; zinc finger protein; circadian clock rhythms
