RGA1 (TRAESCS3D02G502400) — triticum aestivum

Summary

TRAESCS3D02G502400, also known as RGA1, TaL5, or TaSUT1 on bread wheat chromosome 3D, encodes an NB-ARC domain-containing protein with ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase activity and ATP/ADP binding. This gene is associated with sucrose transport, starch and amylopectin metabolism, grain filling, grain size and weight, and sucrose content. It has been linked to salt stress tolerance, drought tolerance, freezing tolerance, and low temperature stress response. Additional associations include defense responses to bacteria and other organisms, antiviral response, innate immune signaling, hypersensitive response programmed cell death, and cell death. The encoded protein localizes to the plasma membrane and cytoplasm. Studies of related genes in other species link the family to AAA+ ATPase domains and ADP-ribosyl cyclase activity.
