刘永秀，研究员，博士生导师。1993年和1996年分获沈阳农业大学学士和硕士学位，1999年获中国农业大学博士学位。1999年至2000年在中国农业大学任教师，2000年至2002年在德国Technische Universitat München进行客座研究。2002年至2009年在德国Max-Planck Institute for Plant Breeding Research 研究所进行博士后研究。2008年10月到植物所工作，主要从事种子休眠萌发分子基础方面研究，已在Nat Commun、Plant Cell、Plant Physiol、New Phytol等刊物发表论文30余篇。

主要研究工作：

1. 拟南芥种子休眠萌发分子遗传调控

种子休眠萌发是植物由生殖生长转变为营养生长的关键发育进程，关乎植物的生存与繁衍。课题组主要利用突变体和自然变异QTL等分子遗传手段研究拟南芥种子休眠萌发的调控机制，已研究报道了RDO4（HUB1）、 RDO2、SNL1/SNL2、RDO3(ETR1)、Sdr4L、FT等调控种子休眠萌发的分子机理，从表观遗传和植物激素等不同角度阐明了种子休眠萌发调控的分子通路。目前研究重点：DOG3的克隆和功能研究，种子储藏mRNA与种子休眠萌发，种子休眠萌发特异性调控分子网络解析等。

2. 作物抗穗发芽分子模块解析

穗发芽是影响作物产量及品质的气候灾害之一，主要发生在收获季节降雨多的地区。适度提高种子休眠水平是抑制穗发芽的关键，但目前对作物种子休眠形成的分子基础了解甚少。课题组主要利用小麦遗传群体和种质资源开展QTL连锁分析和全基因组关联分析，克隆调控小麦种子休眠的关键基因，为分子育种提供有效标记和优异基因资源。

3. 饲草燕麦耐盐碱分子元件解析

针对饲用燕麦生产中面临的生物量低、耐盐碱性差等问题，利用燕麦种质资源和遗传分离群体，通过全基因组关联分析、QTL连锁分析及组学等技术手段，解析饲用燕麦耐盐碱的分子元件，克隆饲用燕麦耐盐碱基因，发掘有效分子标记，培育携带耐盐碱分子元件且农艺性状优良的燕麦新材料。
