EHD1 — Oryza sativa Japonica

Summary

Os02g0158100, designated EHD1 in rice (Oryza sativa Japonica) on chromosome 2, encodes a protein containing an EH domain, dynamin and EF-hand domains, and is annotated with GTP binding, calcium ion binding, protein kinase activity, and protein binding, bridging functions. EHD1 is associated with photoperiod sensitivity, heading date, and flowering time, as well as with grain number, grain weight, grain length and width, panicle length, tiller number, seed size, and yield traits. The gene product is linked to flower formation, photoperiodism, endocytic recycling, endosomal transport, cytokinin and abscisic acid anabolism, and chromatin modeling. It localizes to the endosome membrane, plasmodesma, nucleus, and cytosol. Studies of related genes in other species link the family to plant immunity and endocytosis.
