WSCP — Brassica oleracea var. botrytis

Summary

BoWSCP, encoded by gene BOLND125_C02P039340.1 on cauliflower chromosome 2, is a Kunitz-type protease inhibitor family member with peptidase inhibitor activity, including cysteine-type endopeptidase inhibitor activity, and also exhibits protein binding and cysteine-type peptidase activity. In cauliflower, BoWSCP is associated with chlorophyll breakdown, photoprotection, programmed cell death, response to herbivores and insects, wounding, defence against fungi, regulation of pollen tube growth and stomatal closure, and electron transfer. It localises to the apoplast, plant-type cell wall, vacuole, plasmodesma, secretory vesicles, stress granules, and P bodies. The gene is linked to drought tolerance, leaf senescence, salt tolerance, root morphology, photochemical quenching, and clubroot resistance. Related genes in other species connect the family to herbivore defence, cell wall composition, and susceptibility to Heterodera schachtii.
