Rice G-protein coupled receptor (GPCR): in silico analysis and transcription regulation under abiotic stress.

ABSTRACT: Majority of transmembrane signal transduction in response to diverse external stimuli is mediated by G-protein coupled receptors (GPCRs) and are the principal signal transducers. GPCRs are characterized by seven membrane-spanning domains with an extracellular N-terminus and a cytoplasmic C-terminus which functions along with GTP-binding protein in a highly coordinated fashion. Role of heterotrimeric G-proteins in abiotic stresses has been reported, but the response of GPCR is not yet well characterized. In the present study we report the isolation of one putative GPCR (966 bp) from Indica rice (Oryza sativa cv. Indica group Swarna) and described its transcriptional regulation under abiotic stresses. Amino acid sequence analyses shows the presence of typical heptahelical transmembrane spann
