Although positive control or activation mechanism(s) involved in plant defence- and stress-related gene expression is relatively well studied, little is known about what keeps defensive armoury under control when not needed. Recent reports suggest that transcriptional repression of gene expression by EAR-motif-containing repressor proteins plays a key role in modulating plant defence and stress responses.
尽管植物防御和应激相关基因表达所涉及的正向调控或激活机制已得到较为充分的研究,但对于在不需要时如何控制防御机制却知之甚少。最近的报告表明,含EAR基序的阻遏蛋白对基因表达的转录抑制在调节植物防御和应激反应中起关键作用。
