EHD1 — Oryza sativa Indica Group

Summary

BGIOSGA017326 (EHD1, OiEHD1) on chromosome 4 of Indica rice encodes a protein with GTP binding, calcium ion binding, protein kinase activity, and protein tag functions, containing dynamin, EF-hand, and EH domains. It is associated with photoperiod sensitivity and heading date, as well as basic vegetative growth period. The gene is linked to endocytic recycling, endosomal transport, regulation of actin cytoskeleton organization, and protein homooligomerization. It has been connected to grain weight, grain yield, days to heading, anthesis time, root thickness, and plant tissue development. Associations also include responses to heat, oxidative stress, osmotic stress, abscisic acid, manganese sensitivity, and disease tolerance. The protein localizes to endosome membranes, plasmodesmata, the nucleus, and cytosol. Studies of related genes in other species link the family to flowering time, plant immunity, endocytosis, root growth, and thermo-resilience.
