Credit Seminar on Epigenetics for Plant Trait Improvement

Epigenetics generally is used in reference to a class of heritable molecular events involving a wide variety of protein complexes and regulatory mechanisms that do not involve change in the DNA Sequence . Genetic information alone cannot fully address the fundamental question of how genes are differentially expressed during cell differentiation and plant development, as the DNA sequences in all cells in a plant are essentially the same. Numerous studies have unveiled the importance of several mechanisms in regulating transcription by affecting the structural properties of the chromatin. These mechanisms, including DNA cytosine methylation, modifications of histones, and certain aspects of RNA interference (RNAi), are referred to as epigenetic. Some epigenetic tags remain in place as genetic information passes from generation to generation, a process called epigenetic inheritance. Plants use these epigenetic silencing mechanisms extensively to control development and parent-of-origin imprinted gene expression.
Understanding how epigenetic regulation is involved in plant response to environmental stress is highly desirable, not just for a better understanding of molecular mechanisms of plant stress response but also for possible application in the genetic manipulation of plants. Apart from silencing mechanism and environmental stress regulation; Plant immunity, Vernalization, Seed development, Fruit development regulation by epigenetically sheds light on better understanding of gene expression.
