Omics Study for Abiotic Stress Responses in Plants

Abstract

Abiotic stresses, such as drought, temperature extremes and salinity, are the major constraints on crop yield and quality in fields. Transcriptomics, proteomics and metabolomics have been employed to improve understanding of the biological processes and molecular/cellular mechanisms involved in plant stress responses. Over the last several decades, in the light of research carried out using different omics approaches, various stress related mechanisms have been proposed for the development of tolerant varieties. Integrated use of functional genomics helps in understanding the relationship between an organism’s genome and their phenotype under different environmental conditions. By exploiting available genetic information and continuously improving techniques and strategies, integrated functional genomics alongside bioinformatics will provide a foundation for further in-depth functional studies of stress tolerance in plants.
