CEF1 — triticum aestivum

Summary

TaCEF1 (TRAESCS7A02G304500) on wheat chromosome 7A encodes a protein with a SANT/Myb domain and a homeodomain-like superfamily fold, possessing sequence-specific DNA-binding and transcription cis-regulatory region binding activities. The gene is associated with regulation of secondary cell wall biogenesis, regulation of lignin anabolism, activation of syringyl lignin anabolism, pigment accumulation, phlobaphene biosynthesis, and flavonoid anabolism. It is linked to defence response to fungi, upregulation of defense response to insect, response to wounding, and green leaf volatile biosynthetic process. TaCEF1 is associated with grain number, grain size, grain texture, grain shattering, spikelet fertility, tiller number, days to heading, canopy temperature, water use efficiency, net photosynthetic rate, heat tolerance, salt response, wheat stripe rust disease response, stem solidness, anther extrusion, pollen fertility, and leaf senescence rate. The protein localises to the nucleus. Studies of related genes in other species link the family to anther development, tapetum development, male fertility, pollen exine formation, and trichome branching.
