MRF1 — Asparagus officinalis

Summary

A4U43_C02F9210 (MRF1) in asparagus (Asparagus officinalis) on chromosome 2 encodes an MI domain-containing protein with PDCD4 and initiation factor eIF4G-related domains. The gene product is annotated with multiple molecular functions including DXP-synthase activity, ethene binding, ribosome binding, calcium-dependent protein serine/threonine kinase activity, histidine kinase activity, histone binding, microtubule binding, chromatin binding, transmembrane receptor protein serine/threonine kinase activity, and protein kinase activity. MRF1 is associated with diverse biological processes such as response to carbon starvation, jasmonic acid/ethene-dependent systemic resistance, the MEP pathway, regulation of stomatal opening, root hair cell differentiation, auxin polar transport, chlorophyll anabolism, defense response by callose deposition, and phloem or xylem histogenesis. The gene is linked to traits including biomass yield, seed yield, carotenoid content, water use efficiency, leaf elongation rate, nitrate transport, and responses to aphids, aluminum, and osmotic stress. It localizes to the ER, Golgi, plasmalemma, cytosol, and nucleus.
