EHD1 — Oryza sativa Japonica

Summary

OsEHD1 (OS04G0669300) on rice chromosome 4 encodes a protein with dynamin, EF-hand, and EH domains, and has been annotated with GTP binding, calcium ion binding, protein kinase activity, and protein binding, bridging, and tagging functions. It is associated with photoperiod sensitivity and heading date, as well as with flowering, photoperiodism, endocytic recycling, endosomal transport, and regulation of actin cytoskeleton organization. The gene is linked to numerous agronomic traits including grain number, grain weight, grain length and width, panicle length, tiller number, plant height, leaf dimensions, seed size, heading time, anthesis time, yield, heterosis, and stress responses such as oxidative stress, abscisic acid sensitivity, and disease tolerance. It localizes to endosomes, the plasma membrane, cytosol, and nucleus. Studies of related genes in other species link the family to plant immunity and endocytosis.
