Abstract Plant responses to abiotic stresses are dynamic, following the unpredictable changes of physical environmental parameters such as temperature, water and nutrients. Physiological phenotypical stress intercalated by periods recovery. An earlier can be remembered ‘stress memory’ mount a response within generation or transgenerationally. The priming’ phenomenon allows plants respond quickly more robustly stressors increase survival, therefore has significant implications for agriculture. Although evidence memory in various plant species is accumulating, understanding mechanisms implicated, especially crops agricultural interest, its infancy. Rice major food crop which susceptible causing constraints on cultivation yield globally. Advancing network will thus have impact rice sustainable production global security face climate change. Therefore, this review highlights effects priming tolerance focuses specific aspects memory, perpetuation regulation at epigenetic, transcriptional, metabolic well physiological levels. open questions future directions exciting research field also laid out.

Maintenance of abiotic stress memory in plants: Lessons learned from heat acclimation

The Plant Cell, Journal Year: 2022, Volume and Issue: 35(1), P. 187 - 200

Published: Oct. 22, 2022

Abstract Plants acquire enhanced tolerance to intermittent abiotic stress by employing information obtained during prior exposure an environmental disturbance, a process known as acclimation or defense priming. The capacity for memory is critical feature in this process. number of reports related plant (PSM) has recently increased, but few studies have focused on the mechanisms that maintain PSM. Identifying components involved maintaining PSM difficult due part lack clear criteria recognize these components. In review, based what been learned from genetic heat memory, we propose identifying regulatory networks We provide examples circuits formed effectors and regulators also highlight strategies assessing PSMs, update progress understanding maintenance, perspectives further development exciting research field.

Epigenetic processes in plant stress priming: Open questions and new approaches

Current Opinion in Plant Biology, Journal Year: 2023, Volume and Issue: 75, P. 102432 - 102432

Published: July 29, 2023

Priming reflects the capacity of plants to memorise environmental stress experience and improve their response recurring stress. Epigenetic modifications in DNA associated histone proteins may carry short-term long-term memory same plant or mediate transgenerational effects, but evidence is still largely circumstantial. New experimental tools now enable scientists perform targeted manipulations that either prevent generate a particular epigenetic modification location genome. Such 'reverse epigenetics' approaches allow for interrogation causality between individual priming-induced role altering gene expression performance under Furthermore, combining site-directed manipulation with conditional cell-type specific promoters creates novel opportunities test engineer spatiotemporal patterns priming.

Abstract Plants are often exposed to recurring adverse environmental conditions in the wild. Acclimation high temperatures entails transcriptional responses, which prime plants better withstand subsequent stress events. Heat (HS)-induced memory results more efficient re-induction of transcription upon recurrence heat stress. Here, we identified CDK8 and MED12, two subunits kinase module co-regulator complex, Mediator, as promoters associated histone modifications Arabidopsis. is recruited heat-stress genes by HEAT SHOCK TRANSCRIPTION FACTOR A2 (HSFA2). Like HSFA2, largely dispensable for initial gene induction HS, its function thus independent primary activation. In addition promoter start region target genes, also binds their 3ʹ-region, where it may promote elongation, termination, or rapid re-initiation RNA polymerase II (Pol II) complexes during bursts.
