POLYPEPTIDE REGULATING AND CONTROLLING THE FORMATION OF PLANT AGRONOMIC TRAIT OR YIELD TRAIT, AND USE OF POLYPEPTIDE

摘要

The invention relates to a polypeptide for regulating agronomic characters and yield characters of plants and application thereof. The invention alters agronomic characters and yield characters of plants such as root development, tillering ability, heading period, panicle structure, grains number per panicle, grain morphology, and 1000 grains weight by directional regulating expression level of cytokinin-O-glycosyltransferase 1 in plants, thus achieve the aim of modifying plant type, panicle structure, grain morphology and weight, increasing yield.
