EF1 — Oryza sativa Indica Group

Summary

BGIOSGA031750 (symbol EF1, also known as Ehd1) on chromosome 10 of Indica rice encodes a protein with sequence-specific DNA binding and DNA binding transcription factor activity, belonging to the LUX/BOA-like and Myb domain families and containing a CheY-like receiver domain. The gene is associated with the upregulation of short-day photoperiodism, flowering, histidyl-aspartyl phosphorelay, cytokinin signaling, and flower development, and its product localises to the nucleus. Observed phenotypes include effects on heading date, flowering time, leaf, flower, and yield. The gene is also linked to grain weight, grain yield, days to heading, anthesis time, panicle and spikelet traits, plant height, and shoot and meristem development. Studies of related genes in other species connect the family to additional yield-related traits such as grain number, tiller number, seed size, and drought tolerance.
