SEC — Phaseolus vulgaris

Summary

PHAVU_L002532, designated SEC (PvSEC), encodes a peptide-O-fucosyltransferase with OGTase and transglycosidase activity, belonging to the OGT/SEC/SPY_C and Sel1-like families. In French bean, it is associated with protein O-linked glycosylation, GA-signaling, the transition from vegetative to reproductive phase, and downregulation of flower development. The gene is associated with response to water and response to stress, and its product localizes to the cytoplasm and nucleus. Associations include flowering time, leaf production rate, reproductive development, and response to Plum pox virus infection. Studies of related genes in other species connect the SEC family to leaf elongation rate, root hair density, gibberellic acid sensitivity, seed development, and viral disease response traits.
