INSPIRE Faculty produced heat-tolerant wheat varieties resulting in improved grain yield

News: Researchers of the INSPIRE Faculty under the Department of Science and Technology(DST) are studying to develop a variety of wheat that does not lose its productivity under heat stress.

Facts:

    • Wheat and Heat Stress: Wheat is affected severely by Heat stress as it causes a dramatic reduction in yield as well as quality of wheat which is the staple for more than one-third of the world’s population.

What are the researchers studying and developing?

    • The researchers are studying the role of DNA methylation (a biological process by which methyl groups are added to the DNA molecule) patterns as it plays a significant role in plant development as well as in heat stress tolerance during different grain filling stages.This study is carried out through a process called epigenomic mapping.
    • It will explore the epigenetic route to modify gene expression in a manner that is stably transmitted but does not involve differences in the underlying DNA sequence so that the heritable genes do not buckle under heat stress and non-stress conditions during different grain filling stages.
