WSCP — Brassica oleracea

Summary

BoWSCP, encoded by gene BOLC102_C02P034040.1 on cabbage chromosome 2, belongs to the Kunitz inhibitor STI-like superfamily and possesses peptidase inhibitor activity, specifically cysteine-type endopeptidase inhibitor activity, as well as protein binding and cysteine-type peptidase activity. The gene is associated with responses to herbivores, insects, wounding, and fungal defence, along with programmed cell death, regulation of pollen tube growth and stomatal closure, protein denaturation, and protein ubiquitination. It has been linked to drought tolerance, leaf senescence, salt tolerance, root morphology, and clubroot resistance. The product localises to the apoplast, plant-type cell wall, vacuole, plasmodesma, secretory vesicles, stress granules, and P bodies. Related genes in other species connect the family to herbivore defence, cell wall composition, and susceptibility to Heterodera schachtii.
