基因组编辑技术可以定向修饰植物基因组，从而大大加速植物育种的进程，是实现作物精准育种的重要技术突破。然而，作物的许多重要农艺性状是由基因组中的单个或少数核苷酸的改变或突变造成的。基于CRISPR/Cas系统的基因组编辑，可利用外源修复模板通过同源重组介导的修复方式（HDR）实现目标基因特定核苷酸的改变。目前，同源重组在植物中的效率非常低，很难以此方式实现高效、稳定的植物基因组的精准编辑。CRISP...
植物表观遗传学，通过遗传，生化，蛋白质组和基因组的手段探索和阐释DNA和组蛋白的表观遗传学修饰原理，及其在基因表达，基因组稳定性中的作用机制。具体关注DNA和组蛋白的表观遗传修饰对染色质的高级结构的影响，和在细胞分子水平对生物发育的作用。我们以拟南芥为主要的模式研究对象，同时也关注表观遗传学在作物和裸子林业植物中的应用。
