Description Accepted date: 19 November 2016
Plants have developed intricate mechanisms to overcome abiotic stresses. The process of signal perception and activation of signaling cascades involves a large number of factors and molecules belonging to diverse classes of gene families. In comparison to animals, plants harbor larger multigene families along with the occurrence of plant-specific ones. Gene families with abiotic-stress-responsive members were analyzed and categorized into classes such as transcription factors, signal transduction components, transporters, epigenetic regulators, and other regulatory components. The number of members, phylogeny, family expansion, domain composition, subcellular localization, and expression profiling during varied abiotic stresses have been summarized. Candidate genes from families, functionally characterized for abiotic stress responses, have been described. Based on our compilation, the expansion of abiotic-stress-responsive gene families in rice has occurred via segmental and tandem duplication events to accommodate sub-functionalization needed for regulating diverse abiotic stress responses at expression, localization, and functional levels. The information documented here can be further utilized as a primer for selecting candidate genes for improvement of rice yield under abiotic stresses.
Our research on abiotic stress in rice is supported by the
Department of Biotechnology and the Department of Science
and Technology, Government of India.
