Gene Bank Accession Number of RGG1: GU111573.1 Locus: GU111573 Online published on 5 August, 2017. Abstract The heterotrimeric G-protein complex, comprising of G α, G β, and G λ subunits. It is an evolutionarily conservedsignaling molecular machine which transmits signals from transmembrane receptors to downstream target proteins. Now-a-days their functions in plant stress-signalling have been reported. Here we report the physiological function of rice G-protein λ subunit (RGG1) rice (Oryza sativa L. cv. IR64) plants under salinity stress in T3 generation. The overexpression of CaMV35S promoter driven RGG1 in transgenic rice confers high salinity (200 mM NaCl) stress tolerance. Agronomic parameters were studied and found to be higher in the transgenic plants with respect to wild type (WT) plants. Top Keywords Antioxidative enzymes, G-protein gamma interacting partners, oxidative stress, hormones, RGG1, salinity stress tolerance, transgenic rice. Top |
