RGA2 — Solanum tuberosum

Summary

PGSC0003DMG400016823, also known as RGA2, SUT1, StRSG1, or StSUT1, on potato chromosome 10, encodes a nucleotide binding site-leucine rich repeat (NBS-LRR) protein with DPNase, NADP nucleosidase, and ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase activities. The gene is associated with sucrose transport, phloem loading and unloading, tuber development, and abiotic stress tolerance. It is linked to gibberellin and ABA signaling, defense responses, programmed cell death, and antiviral responses. The encoded protein localizes to the membrane, plasmalemma, and cytoplasm. Associations with tuber morphology, relative growth rate, and gibberellic acid sensitivity have also been noted.
