主要研究领域：

线粒体和叶绿体是植物细胞中两个重要的细胞器，与能量代谢密切相关。在原始内共生体转向细胞器的进化过程中，叶绿体和线粒体的大多数基因发生了丢失或转移到宿主的核基因组上，也伴随着大量参与控制细胞器基因表达的细胞核编码因子的进化。理解细胞核与细胞器之间的互作关系不仅对研究核质基因协同进化具有重要科学意义，也将为植物杂交育种和杂种优势利用提供理论依据。

本实验室旨在研究核基因与线粒体和叶绿体基因之间的功能和遗传基础，重点关注线粒体和叶绿体基因表达分子机制及空间网络，以深入探讨核质互作在植物发育、繁殖以及环境适应方面的关键作用。同时建立细胞器遗传转化和基因编辑平台，促进杂种优势的利用和植物遗传改良。

主要包括：

1）细胞器转录后表达调控

2）细胞质雄性不育与育性恢复

3）细胞器基因编辑

研究成果：

1) 揭示了十字花科作物细胞质雄性不育与育性恢复的分子机制 (PNAS, 2021; JXB, 2013; Mol. breeding, 2015; Mol. breeding, 2017)；

2) 鉴定了核糖体蛋白等RNA结合蛋白参与细胞器内含子剪接事件 (Nucleic Acids Research 2024; PNAS, 2020; JXB, 2018);

3) 较系统地阐明了线粒体 RNA 的 3’ 端加工成熟的多样性分子机制及其与内含子反式剪接的内在联系(Nucleic Acids Research, 2017; Nucleic Acids Research, 2023; Plant Physiology, 2022).
