Genome Editing in Medicinal Plants for Abiotic Stress Tolerance

Abstract

<div>In the changing climate scenarios, living organisms have been facing several</div><div>biotic and abiotic stresses. Abiotic stresses are the major factors posing huge threats to</div><div>plants. Drought, heat, and salinity are bigger problems emerging in the world due to</div><div>climate change. For adapting various climatic conditions, plants trigger several</div><div>biochemical and molecular mechanisms. At the biochemical level, secondary</div><div>metabolites play an important role in the survival of plants in uneven situations.</div><div>Modulation of expression of genes and stress response elements is observed under</div><div>stress. To cope with abiotic stresses in medicinal plants, the understanding of the</div><div>biochemical and molecular mechanisms is very important. The use of modern</div><div>biotechnological approaches along with conventional breeding may be helpful in</div><div>developing tolerance against abiotic stresses in medicinal plants. This chapter</div><div>highlights various abiotic stresses, their mechanisms and strategies to develop tolerance</div><div>against these stresses.</div>
