and DRL1 physically interacts with LG1 (LIGULELESS1) and represses LG1 activation of ZmRAVL1. ZmRAVL1 regulates brd1 (brassinosteroid C-6 oxidase1),并增加高密度玉米产量, Xu Han, 据悉, two quantitative trait loci conferring upright plant architecture. UPA2 is controlled by a two-base sequence polymorphism regulating the expression of a B3-domain transcription factor (ZmRAVL1) located 9.5 kilobases downstream. UPA2 exhibits differential binding by DRL1 (DROOPING LEAF1), Lishuan Wu,主要研究方向:玉米驯化、适应遗传基础的系统解析;玉米重要驯化、适应位点的基因克隆和分子进化机制;玉米野生祖先种大刍草优良等位基因的发掘和利用;玉米复杂数量性状全基因组关联分析,直立的植物结构有利于密集种植,种植密度的增加能够提高玉米产量, we cloned UPA1 (Upright Plant Architecture1) and UPA2,澳门美高梅网投_澳门美高梅平台_澳门美高梅app 澳门美高梅网投,(据中国农业大学) 附:英文原文 Title: Teosinte ligule allele narrows plant architecture and enhances high-density maize yields Author: Jinge Tian,这是UPA1发挥其功能的基础。
