玉米是我国最重要的粮食作物之一,其生产常常受到干旱等自然灾害的威胁,在干旱严重的年份或区域甚至面临绝收的危险。发掘控制玉米耐旱性的遗传位点、克隆玉米耐旱基因、揭示其生物学功能的分子机理,具有重要的研究价值和应用价值。中国科学院植物研究所秦峰研究组利用全球不同地区的玉米材料组成的自然变异群体,运用全基因组关联分析研究策略,发现位于玉米第10号染色体上的一个编码NAC转录因子的基因Zm NAC111对玉米耐
Corn is one of the most important food crops in our country and its production is often threatened by natural disasters such as droughts and even at the risk of total loss during periods of severe drought or area. Exploring the genetic loci that control drought tolerance of maize and cloning the genes of drought tolerance in maize and revealing the molecular mechanism of its biological functions have important research value and application value. Institute of Botany, Chinese Academy of Sciences, Qin Feng research groups using different parts of the world corn material consisting of natural variation groups, using genome-wide association analysis of research methods and found on maize chromosome 10, a gene encoding NAC transcription factor Zm NAC111 on corn Resistance
