MAPK3 — Glycine max

Summary

GLYMA_14G028100V4, also known as GmMAPK3 or GmMPK20, encodes a mitogen-activated protein kinase (MAPK) with protein serine/threonine kinase activity, ATP binding, and ERK1-type signalling capacity. The product contains a MAP kinase active site and a protein kinase domain. In soybean, this gene is associated with numerous biological processes including polyamine and glutamate metabolism, RNA and glycoside biosynthesis, response to UV-A, nucleus organization, and protein storage. It has been linked to agronomically important traits such as seed weight and size, seed maturation, plant height, stem diameter, petiole length, protein content, calcium concentration, and shoot meristem development. Additionally, GmMAPK3 is associated with stress tolerance traits including drought tolerance, submergence tolerance, salt tolerance, and oxidative stress response. The protein localises to both the cytoplasm and nucleus. Studies of related genes in other species link the family to salt response.
