主要研究方向

1. 植物耐逆性形成的分子机制

逆境胁迫是造成作物减产的重要因素。随着全球气候变化的加剧，土壤盐渍化和极端温度等都对作物高产稳产造成了严重的挑战。团队通过综合生物化学、分子生物学、遗传学、植物生理学等多种手段解析了植物在多水平多维度对耐逆性的调控机制。发表了多篇高水平研究论文(Rice Science, 2024; Int. J. Biol. Macromol. 2023; Antioxidants, 2024; Int. J. Mol. Sci. 2022; New Phytologist, 2021; Plant Cell, 2016; Nucleic Acids Research, 2015)

2. 作物重要农艺性状形成的遗传调控网络

优质高效、高产稳产是作物育种所追求的目标。团队利用突变体材料、优异种质资源、定向突变库等资源，解析了调控作物株型、粒形、花期、产量等多个关键性状的遗传调控机制。发表了多篇高水平研究论文(Physiologia Plantarum, 2024; Crop Journal, 2023; Int. J. Mol. Sci. 2023; Journal of Plant Biology, 2022; Molecular Plant, 2021; Nature Communications,2021; Plant Physiology, 2018)

3. 作物高产优质耐逆新品种的分子改良

分子聚合育种是未来发展方向。相较于传统育种，分子聚合育种能极大地缩短育种周期，加速品种迭代，培育更能适应环境变化的智能作物。团队在解析向日葵抗列当的分子机制基础上，利用开发的分子标记极大地缩短了育种进程。与新疆农科院共同培育抗列当品种2399，通过了国家向日葵新品种登记。
