Identification of gene family in and expression analysis of under various adversities.

Unlabelled: Glycoside hydrolase (GH, EC 3.2.1) is a group of enzymes that hydrolyzes glycosidic bonds and play a role in the hydrolysis and synthesis of sugars in living organisms. is an important fruit crop and it harbors gene family however, their function in grapes has not been systematically investigated. In this study, a total of 870 genes were identified from 14 plant species and their structural domain, sequence alignment, phylogenetic tree, collinear analysis, with the expression profiles of gene family was performed. The promoter analysis of gene showed the presence of -acting elements, which are responsive to plant growth and development. In addition, elements for plant hormones were found that are triggered in response to abiotic/biological stress. Transcriptomic data led to the identification of several genes, which are associated with bud dormancy and in response to abiotic stress. Transcript analysis was carried out for some of the selected genes RT-qPCR. and genes were differentially expressed during bud dormancy, fruit development and different abiotic stresses. Moreover, and were differentially expressed at fruit development, in response to abiotic stress. In addition, subcellular localization predicts that the , , and genes were located in the cell membrane, while gene was located in the vacuole. In conclusion, our study led to the identification of several and their probable role in development and stress.
