RGA3 — Beta vulgaris subsp. vulgaris

Summary

BVRB_7G168360, also known as RGA3 or BvSUT1, encodes a protein with DPNase, NADP nucleosidase, and ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase activities, and contains NB-ARC and P-loop_NTPase domains characteristic of disease resistance proteins. In sugar beet, this gene is associated with sucrose transport, carbon export, and phloem sucrose loading, as well as phloem loading, NAD breakdown, upregulation of programmed cell death, defense responses to other organisms and fungi, antiviral response, hypersensitive response-programmed cell death, protein phosphorylation, signal transduction, and nitric oxide storage. The product localizes to the plasmalemma, cytoplasm, and nucleus. Studies of related genes in other species link the family to pathogen recognition and defense signaling.
