MT1 — Phaseolus vulgaris

Summary

PHAVU_L001645, designated PvMT1, encodes a metallothionein family protein (Metalthion_15p domain) with copper and metal binding activity. The gene is associated with nuclear export, nitrogen fixation, nodulation, cell growth regulation, and response to high light intensity and copper. It localises to the cytosolic ribosome. PvMT1 has been linked to photosynthetic rate, cadmium and copper accumulation, copper and zinc homeostasis, cadmium tolerance, metal accumulation, copper response, and leaf senescence. Studies of related genes in other species connect the family to copper tolerance, heavy metal tolerance and accumulation, cold and light stress responses, and traits including root nodule number, net photosynthetic rate, transpiration rate, stem elongation, germination rate, leaf senescence, root length, drought tolerance, and salt tolerance.
