MMP — Brassica oleracea var. botrytis

Summary

BoMMP, the cauliflower gene on chromosome 6, encodes a protein with metallopeptidase and metalloendopeptidase activity that binds zinc. The encoded protein belongs to the M10A_MMP family and is associated with proteolysis, collagen breakdown, and extracellular matrix organization. It has been linked to developmental vegetative growth, cell growth, negative regulation of leaf senescence, regulation of photoperiodism and flowering, nuclear import, and responses to jasmonic acid, cadmium, and salinity. The protein localizes to the extracellular matrix, apoplast, and membrane. Studies of related genes in other species connect the family to leaf senescence, flowering time, plant growth, and resistance to both necrotrophic and biotrophic fungal pathogens, including Botrytis cinerea.
