SEC — Pisum sativum

Summary

PSAT6G140720 (SEC, also known as SPY) on chromosome 6LG2 encodes a protein with peptide-O-fucosyltransferase activity, OGTase activity, and transglycosidase activity, belonging to the OGT protein family and containing TPR repeats. The gene is associated with protein O-linked glycosylation, protein import, secretion, membrane transport, and proteolysis. It is linked to GA-signaling, the transition from vegetative to reproductive phase, and downregulation of flower development. Phenotypic associations include flowering time, leaf production rate, reproductive development, and response to Plum pox virus infection. The protein localizes to both the cytoplasm and nucleus. Studies of related genes in other species connect the SEC/SPINDLY family to gibberellin signaling, seed development, leaf elongation, root hair density, and viral disease response traits.
