HD2 — Medicago truncatula

Summary

MTR_4G035200, also known as MtHD2, encodes a protein with histone deacetylase activity, transmembrane receptor protein serine/threonine kinase activity, and chromatin binding, among other molecular functions. It is associated with diverse biological processes including seed dormancy, response to nitrate, organogenesis, regulation of RNA splicing, and actin depolymerization. The gene has been linked to numerous agronomically relevant traits such as nitrogen content, phosphorus uptake, root hair length, lateral root length, flower morphology, leaf morphology, stem senescence, and anthocyanin content, and is associated with responses to abiotic stress including high temperature and cadmium tolerance. It is also connected to phenotypes like drought resistance, seed development, fertility, and stomatal aperture. Related genes in other species link the family to gene expression, rRNA synthesis, and stress tolerance.
