MT1 — Pisum sativum

Summary

PSAT7G239160 (MT1, MTA) on garden pea chromosome 7LG7 encodes a metallothionein family protein with copper- and metal-binding molecular functions. It is associated with tRNA decay, response to copper, and response to high light intensity, and localises to the cytosolic ribosome. The gene has been linked to photosynthetic rate, cadmium and copper accumulation, copper and zinc homeostasis, cadmium tolerance, metal accumulation, copper response, and leaf senescence. Related genes in other species connect the family to heavy metal tolerance, copper distribution, cold and light stress responses, and traits including root nodule number, copper sensitivity, net photosynthetic rate, cadmium concentration, transpiration rate, stem elongation, germination rate, leaf senescence, root length, drought tolerance, and salt tolerance.
