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.
