摘要

转录记忆可使生物体存储有关转录重编程的信息,以应对刺激。在植物中,这通常涉及对非生物胁迫的反应,在自然界中,这种胁迫可能是周期性的或反复出现的。这种转录记忆可在应对反复出现的刺激时赋予持续的诱导或增强的再激活,从而增加生存和健康的机会。热胁迫(HS)已成为研究植物转录记忆的绝佳模型系统,在阐明这一现象的分子机制方面也取得了很大进展。在此,我们回顾了组蛋白周转和转录共调控复合物如何促进转录反应的重编程。

Mechanisms of heat stress-induced transcriptional memory

Transcriptional memory allows organisms to store information about transcriptional reprogramming in response to a stimulus. In plants, this often involves the response to an abiotic stress, which in nature may be cyclical or recurring. Such transcriptional memory confers sustained induction or enhanced re-activation in response to a recurrent stimulus, which may increase chances of survival and fitness. Heat stress (HS) has emerged as an excellent model system to study transcriptional memory in plants, and much progress has been made in elucidating the molecular mechanisms underlying this phenomenon. Here, we review how histone turnover and transcriptional co-regulator complexes contribute to reprogramming of transcriptional responses.
