MT2 — Asparagus officinalis

Summary

AoMT2 (MT2) on asparagus chromosome 7 encodes a metallothionein-family protein with metal-binding, copper-binding, poly-A-binding, CDK, protein kinase and protein-binding activities. It is associated with cellular copper ion homeostasis, symmetric cell division, regulation of meiotic nuclear division, guard mother cell division, regulation of cell cycle G1/S phase transition, chromosome localization, DNA condensation, telomere maintenance via telomerase, upregulation of cell proliferation, stem cell population maintenance, DNA re-duplication, root meristem growth, meiotic cytokinesis, meristem maintenance, cytokinesis by cell plate formation, gametophyte development, guard mother cell differentiation, and circadian rhythm. The gene is linked to seed viability, shoot apical meristem development, trichome morphology, cell cycle, cell elongation, plant embryo development, leaf composition, flowering time, and plant growth and development traits. Phenotypic associations include copper homeostasis, leaf senescence, cadmium tolerance, chromium tolerance, heavy metal tolerance, copper tolerance, copper response, mercury tolerance, salt stress response, cell cycle regulation, cell cycle regulation under cadmium stress, trichome development, cell proliferation competence, S phase entry, stem cell maintenance, and plant growth.
