MMP — Asparagus officinalis

Summary

A4U43_C04F26600 (MMP, AoMMP) on asparagus chromosome 4 encodes a matrix metalloproteinase of the M10A_MMP family, possessing metallopeptidase and metalloendopeptidase activity with zinc binding. This gene is associated with extracellular matrix organization, apoptotic process, cell death, wound healing, and proteolysis. It has been linked to negative regulation of leaf senescence, regulation of photoperiodism and flowering, developmental vegetative growth, cell cycle and G1 phase, as well as responses to jasmonic acid, cadmium, salinity, and defence against fungi. Associations also include drought stress tolerance, auxin transport, root growth, root development, resistance to necrotrophic fungal pathogens, and fungal disease resistance. The encoded protein localizes to the extracellular matrix, apoplast, and plasma membrane. Studies of related genes in other species link the MMP family to plant growth, senescence, flowering time, and susceptibility to Botrytis cinerea.
