EHD1 — Oryza sativa Japonica

Summary

OsEHD1 (EHD1) on rice chromosome 6 encodes a protein with DUF5600, EHD_N, EH_dom, G_DYNAMIN_dom, Dynamin_N, EF_hand_dom, EF-hand-dom_pair, and P-loop_NTPase domains, and is annotated with GTP binding, calcium ion binding, protein kinase activity, and protein binding, bridging, and tagging functions. The gene is associated with photoperiod sensitivity and heading date, as well as flower formation, photoperiodism, and floral transition. It is linked to numerous yield-related traits including grain number, grain weight, grain length and width, seed size, panicle length, tiller number, plant height, and leaf dimensions. Associations also extend to abscisic acid sensitivity and signaling, osmotic and oxidative stress responses, disease tolerance, heterosis, and endocytic recycling, endosomal transport, and regulation of actin cytoskeleton organization. The protein localizes to endosome membranes, the nucleus, plasmodesmata, and the cytosol. Studies of related genes in other species link the family to plant immunity and endocytosis.
