GW8 — Triticum aestivum

Summary

TaGW8 (TRAESCS4D02G332700) on wheat chromosome 4D encodes an uncharacterized protein with DNA-binding transcription activator activity, transcription cis-regulatory region binding, DNA binding transcription factor activity, zinc binding, and protein binding, localised to the nucleus. It is associated with anther development, seed development, the vegetative-to-reproductive phase transition, response to fungi, DNA-dependent transcription, and regulation of DNA-templated transcription. The gene has been linked to panicle length, grains per spike, leaf morphology, grain quality, and yield. Studies of the rice relative SPL18 connect the family to grain number, grain weight, grain width, tiller number, cell proliferation, panicle and spikelet development, and floral transition. Additional family-level associations from sequence similarity include heading time, heat and cold tolerance, seed size, leaf angle, amylose content, and heterosis.
