LG1 — Zea mays

Summary

ZM00001EB067740, designated LG1 (LIGULELESS1) on maize chromosome 2, encodes an SBP-domain transcription activator that localises to the nucleus and binds DNA and zinc. The gene is associated with a wide range of developmental and agronomic traits, including ligule length and formation, auricle development, leaf angle, leaf shape and width, plant height, tassel branch number and angle, ear development and ear aspect, inflorescence branching, phyllotaxy, and plastochron. It has also been linked to grain number, grain weight, grain yield, anthesis time, plant vigor, crop stand, water use efficiency, drought tolerance, heterosis, and ethylene sensitivity. Additional associations include abscisic acid breakdown, brassinosteroid anabolism and content, vegetative phase change, sex determination, and light absorption. Related genes in other species are linked to panicle architecture, leaf inclination, seed shattering, and domestication traits.
