MT1 — Cicer arietinum

Summary

CaMT1 (LOC113787790) on chickpea chromosome 7 encodes a metallothionein family protein with copper- and zinc-binding activity. The gene is associated with cellular copper ion homeostasis, cellular detoxification, digestion, and proteolysis, and its product localises to the extracellular space. CaMT1 is associated with photosynthetic rate, root length, and drought tolerance, as well as with cadmium and mercury tolerance, copper homeostasis, and leaf senescence. Related genes in other species are linked to heavy metal stress tolerance and accumulation, copper distribution and tolerance, and traits including copper sensitivity, net photosynthetic rate, germination rate, salt response, leaf senescence, and root morphology.
