| 英文摘要 | Seeds maintain a dormant state to withstand adverse conditions and germinate when conditions become favourable to give rise to a new generation of flowering plants. seed dormancy and germination are tightly controlled by internal and external signals. although phytochrome photoreceptors are proposed to regulate primary seed dormancy, the underlying molecular mechanism remains elusive. here we show that the reveille1 (rve1) and rve2 transcription factors promote primary seed dormancy and repress red/far-red-light-reversible germination downstream of phytochrome b (phyb) in arabidopsis thaliana. rve1 and rve2 expression is downregulated after imbibition and by phyb. rve1 directly binds to the promoter of gibberellin 3-oxidase 2, inhibits its transcription and thus suppresses the biosynthesis of bioactive gibberellins. in addition, delay of germination 1 also acts downstream of phyb. this study identifies a signalling pathway that integrates environmental light input with internal factors to control both seed dormancy and germination. |
