PP — Pisum sativum
Summary
PsPP (PSAT6G164760) on garden pea chromosome 6LG2 encodes a poly(ADP-ribose) polymerase (PARP) family protein with NAD ADP-ribosyltransferase activity (EC 2.4.2.30) and poly(ADP-ribose) glycohydrolase activity. The product contains PARP regulatory, WGR, SAP, and catalytic domains and localises to the nucleus and nucleolus. PsPP is associated with DNA ADP-ribosylation, protein poly-ADP-ribosylation, double-strand break repair via NHEJ, chromosome condensation, and regulation of DNA repair. It is linked to responses to oxidative stress, abscisic acid, osmotic stress, thirst, and fungal defence, as well as syngamy and NO storage. Trait associations include plant stress response, abiotic stress tolerance, stomatal closure time, root thickness and morphology, flowering time, disease tolerance, salt tolerance, water use efficiency, circadian rhythm, and drought tolerance. Studies of related genes in other species link the PARP family to basal defence, pathogen defence, abiotic stress resistance, and DNA double-strand break repair.
