LAS — Triticum aestivum

Summary

TaLAS (TRAESCS7B02G285500) on wheat chromosome 7B encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. It is associated with axillary shoot meristem initiation, secondary shoot formation, meristem initiation, bundle sheath cell fate specification, radial pattern formation, leaf development, asymmetric cell division, geotropism, response to nutrient and phosphate ion detection, arbuscular mycorrhizae formation, response to symbiotic fungi, and maintenance of protein location in the nucleus. The gene product localizes to both the cytoplasm and nucleus. Studies of related genes in other species link the family to tiller formation, panicle number, spikelet number, grain number, grain weight, grain yield, plant height, root number and length, days to heading, seed shattering, seed germination, shoot branching, axillary bud morphology, and heterosis.
