LAS — triticum aestivum

Summary

TRAESCS6D02G153000, designated TaLAS (also known as TaMOC1-6D, TaSCL18-6D), encodes a GRAS family transcription factor on wheat chromosome 6D. The protein possesses sequence-specific DNA binding and homodimerization activity, and localizes to both the nucleus and cytoplasm. TaLAS is associated with axillary shoot meristem initiation, secondary shoot formation, bundle sheath cell fate specification, radial pattern formation, leaf development, and asymmetric cell division. It is linked to responses to nutrients, phosphate ion detection, geotropism, arbuscular mycorrhizae formation, and symbiotic fungi. The gene is associated with tillering and shoot apical meristem growth. Studies of related genes in other species connect the family to tiller number, panicle number, spikelet number, grain number, grain weight, grain yield, plant height, root number and length, days to heading, seed shattering, and heterosis.
