Epigenetic Regulation in Plant Stress Responses: Mechanisms and Implications
Authors
S B Verma
Abstract
Plants, as sessile organisms, have evolved sophisticated mechanisms to
cope with a wide range of environmental stresses, including drought, salinity,
heat, and pathogen attacks.[1] Beyond the hard-coded genetic
blueprint, epigenetic regulation provides a crucial layer of flexible and
reversible control over gene expression, enabling rapid and dynamic responses
to stress.[2] This review provides a comprehensive overview of the
mechanisms and implications of epigenetic regulation in plant stress responses,
synthesizing key research from the past five years (2020-2024). We detail the
primary epigenetic mechanisms—DNA methylation, histone modifications, and the
action of non-coding RNAs—and explain how they orchestrate the transcription of
stress-responsive genes.[3] We further explore the concept of
epigenetic memory, where stress-induced marks can be maintained to prime future
responses, and the more complex phenomenon of transgenerational epigenetic
inheritance. This paper also presents five detailed tables summarizing recent
findings on how these mechanisms operate in various crops and model organisms.
We conclude by highlighting the potential of epigenetic engineering to develop
climate-resilient crops and outlining future research directions to unravel the
intricate interplay of epigenetic pathways.
