Epigenome and Epitranscriptome: Potential Resources for Crop Improvement.

Area of Science:

• Plant Science
• Genetics
• Biotechnology

Background:

• Crop breeding aims to enhance food production amidst increasing global demand and climate change challenges.
• Traditional breeding relies on genetic diversity, but epigenetic and epitranscriptomic diversity present novel resources for trait improvement.
• Epigenetic modifications regulate gene expression without altering DNA sequence, offering a dynamic layer of heritable variation.

Purpose of the Study:

• To review variations in epigenomes and epitranscriptomes during plant development and in response to environmental stress.
• To identify sources of epiallele formation relevant for crop improvement.
• To discuss strategies for applying epialleles and epitranscriptome engineering in modern crop breeding.

Main Methods:

• Literature review of epigenetics and epitranscriptomics in plants.
• Analysis of epigenetic and epitranscriptomic variations in response to developmental cues and environmental stimuli.
• Synthesis of current knowledge on epiallele formation and engineering strategies.

Main Results:

• Epigenome and epitranscriptome variations are observed during plant development and stress responses.
• Environmental factors and developmental processes contribute to the formation of epialleles.
• Epigenetic and epitranscriptomic modifications provide a source of heritable variation beyond genetic changes.

Conclusions:

• Epigenetic and epitranscriptomic diversity represents a valuable, largely untapped resource for crop breeding.
• Biotechnological approaches to harness epigenetic regulation hold significant promise for developing climate-resilient and high-yielding crops.
• Future research should focus on understanding and applying epiallele engineering for sustainable agriculture.
