MT2 — Cucumis melo

Summary

MELO3C009260.2 (symbol MT2, also known as CmMT2) on melon chromosome 5 encodes a protein with a Metalthion_15p domain, annotated with copper, metal and protein binding, poly-A binding, CDK and protein kinase activities. The gene is associated with cellular copper ion homeostasis, chlorophyll anabolism, root meristem growth, meristem maintenance, symmetric cell division, guard mother cell differentiation, gametophyte development, stem cell population maintenance, and regulation of meiotic nuclear division and cell cycle G1/S phase transition. It localizes to the nucleus, cytoplasm, stress granule, plant-type vacuole, preprophase band and cortical microtubule. Associations include seed viability, shoot apical meristem development, trichome morphology, cell cycle, cell elongation, embryo development, leaf composition, flowering time, and growth traits, as well as copper homeostasis, leaf senescence, and tolerance to cadmium, chromium, copper, mercury and heavy metals. Related genes in other species link the family to salt tolerance, cold stress response, heavy metal accumulation, cell cycle control and nematode resistance.
