A Brief Overview of the Epigenetic Regulatory Mechanisms in Plants

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(10), P. 4700 - 4700

Published: May 14, 2025

Plants continuously adapt to their environments by responding various intrinsic and extrinsic signals. They face numerous biotic abiotic stresses such as extreme temperatures, drought, or pathogens, requiring complex regulatory mechanisms control gene activity proteome for survival. Epigenetic regulation plays a crucial role in these adaptations, potentially leading both heritable non-heritable changes across generations. This process enables plants adjust expression profiles acclimate effectively. It is also vital plant development productivity, affecting growth, yield, seed quality, enabling “remember” environmental stimuli accordingly. Key epigenetic that play significant roles include DNA methylation, histone modification, ubiquitin ligase activity. These processes, which have been extensively studied the last two decades, led better understanding of underlying expanded potential improving agriculturally economically important traits. methylation fundamental regulates altering chromatin structure. The addition methyl groups cytosines methylases leads suppression, whereas demethylases reverse this effect. Histone modifications, on other hand, collectively referred “histone code”, influence structure promoting either transcription silencing. modifications are recognized, added, removed variety enzymes act practically an memory, having impact responses stimuli. Finally, complexes, tag specific histones proteins with ubiquitin, regulation. complexes involved protein degradation regulating cellular activities. intricate interplay between ligases adds complexity our expression, generating branching network interdependent pathways. A deeper helps stressful conditions will provide valuable insights into involved. knowledge could pave way new biotechnological approaches breeding strategies aimed at enhancing crop resilience, sustainable agriculture.

Plant transcriptomes are complex entities shaped spatially and temporally by a multitude of stressors. The aim this review was to summarize the most relevant transcriptomic responses selected abiotic (UV radiation, chemical compounds, drought, suboptimal temperature) biotic (bacteria, fungi, viruses, viroids) stress conditions in variety plant species, including model crops, medicinal plants. Selected basic applicative studies employing RNA-seq from various sequencing platforms single-cell were involved. responsiveness species diversity affected gene families discussed. Under acclimation, respond particularly dynamically. Stress response involved both distinct, but also similar families, depending on tissue, quality dosage stressor. We noted over-representation data for some organs. Studies allow better understanding strategies environmental conditions. Functional analyses reveal stress-affected genes as well acclimatory mechanisms suggest metabolome diversity, among species. Extensive characterization would result development new cultivars that cope with more efficiently.
