Description
This? gene Ubiquitous expression in leaves before flowering (RPKM 48.7), leaves after flowering (RPKM 36.4) and 6 other tissues. It encodes protein Alpha subunit of G proteins (guanine nucleotide binding). G-alpha has three isomers, guanine nucleotide-binding protein alpha-1 subunit isoform X1，guanine nucleotide-binding protein alpha-1 subunit isoform X2，and guanine nucleotide-binding protein alpha-1 subunit isoform X3.RGA1 is one of the regulators in salt response partially through ROS scavenging, which might be helpful in elucidating salt tolerant mechanisms of heterotrimeric G protein in rice(PMID 30621186). The α-subunit of the rice heterotrimeric G protein, RGA1, regulates drought tolerance during the vegetative phase in the dwarf rice mutant d1 (PMID 27194741).? The Gα heterotrimeric G protein subunit, RGA1,? plays an important role in regulating photoprotection and photoprotection of rice (PMID 29216416).
