1、植物 I 型蛋白磷酸酶（TOPP/PP1）的功能。通过遗传学、细胞生物学、分子生物学方法，发现植物蛋白磷酸酶 TOPP 调控赤霉素信号转导、生长素极性运输、光信号通路、免疫反应、细胞自噬，以及ABA信号及非生物胁迫反应等关键过程。TOPP通过对GA信号通路抑制蛋白DELLA去磷酸化修饰，促进其降解，正调控赤霉素信号通路（Qin et al., 2014, PLoS Genetics）；证明TOPP可以对生长素运输蛋白PIN1去磷酸化，调控生长素在表皮细胞内外的极性分布，控制扁平细胞的形态建成（Guo et al., 2015, Plant Physiology）；发现TOPP与phyB在红光下对PIF5进行磷酸化修饰，调节PIF5的降解，参与了植物的光形态建成（Yue et al., 2016, Plant Physiology）；发现蛋白磷酸酶TOPPs参与植物免疫途径（Liu et al., 2019, JIPB），该途径中TOPPs被抗病蛋白SUT1所监护（Yan et al., 2019, The Plant Journal）；揭示了TOPPs的调节亚基PP1R3与其共同组成的全酶与ABI1在细胞核内平行发挥调节ABA信号的作用，为研究TOPP介导的蛋白磷酸化在植物胁迫反应中的作用提供了新途径（Zhang et al., 2020, Plant Physiology）；发现TOPP通过ATG13a的去磷酸化修饰，调控ATG1-ATG13激酶复合体的活性，起始植物细胞自噬（Wang et al., 2022, The Plant Cell）。

2、气孔发育的分子机理。利用遗传学、细胞分子生物学等研究双子叶植物拟南芥、单子叶植物水稻气孔发育的信号转导机制。发现植物甾醇早期合成途径调控气孔系细胞的命运维持和决定，参与调控气孔的图式发育（Qian et al., 2013, The Plant Journal）；发现RNA聚合酶II（Pol II）的亚基NRPB3通过与FAMA和ICE1直接作用，扮演了气孔图式发育过程中转录因子信号接受器的角色，这一策略与肌肉细胞的发育机理类似（Chen et al., 2016, Development）；发现Pol II结合蛋白RIMA-QQT1-IYO复合体能够和气孔发育转录因子SPCH, MUTE, FAMA和SCRM等直接互作，调控气孔系细胞命运的转换，为Pol II结合蛋白参与真核生物细胞和组织分化提供了新机制（Chen et al., 2021, New Phytologist）；鉴定了调控水稻气孔发育的多种转录因子，首次发现OsSCR和OsSHR控制水稻气孔系的起始和发育，且OsSCR 基因的转录受 OsSPCH 与 OsMUTE的激活（Wu et al., 2019, New Phytologist），这一重要发现引发了国际上对禾本科植物气孔发育机理的高度关注，包括The Plant Journal、New Phytologist、Frontiers in Plant Science 等在内的国际知名期刊2020年接连发表多篇综述论文对其引用、讨论和展望；发现FLP-SCRM调控了拟分生组织细胞到气孔母细胞的分化过程（Li et al., 2023, The Plant Journal）。目前主要研究玉米、水稻等禾本科作物的气孔发育遗传调控网络。

3、作物基因编辑育种。利用基因编辑等生物技术培育高产、抗逆的玉米、水稻新品种。

1. The functions of type one protein phosphatase (TOPP/PP1) in plants. Using genetic and molecular biology approaches, our research group illustrated that plant protein phosphatase TOPP regulates gibberellin signal transduction, auxin polar transport, light signaling pathway, defense response, autophagy, and ABA response in plant. TOPP dephosphorylates DELLA, a key GA signaling pathway inhibitor, and promotes its degradation, positively regulating GA signaling pathway (Qin et al., 2014, PLoS Genetics). TOPP also dephosphorylates PIN1, and regulates its polar distribution in the pavement cell, controlling pavement cell morphogenesis (Guo et al., 2015, Plant Physiology). At the same time, TOPP dephosphotylates PIF5, and promotes its degradation during plant photomorphogenesis (Yue et al., 2016, Plant Physiology). TOPP is essential for plant immunity and is guarded by resistance protein SUT1 in plant (Liu et al., 2019, JIPB; Yan et al., 2019, The Plant Journal). Recently, we demonstrate PP1R3, a regulatory subunit of TOPPs, is involved in plant response to abscisic acid and abiotic stress in Arabidopsis (Zhang et al., 2020, Plant Physiology). We find that TOPP regulates the activity of ATG1-ATG13 kinase complex through the phosphorylation state of ATG13a and initiates autophagy in plant cells (Wang et al., 2022, The Plant Cell).

2. The molecular mechanisms of stomata development. Through forward and reverse genetic approaches, we cloned several genes controlling epidermal cell morphogenesis and stomotal patterning in Arabidopsis and rice. For example, early sterol synthesis pathway is required for cell fate commitment and maintenance in stomatal lineage (Qian et al., 2013, The Plant Journal). NRPB3 and NRPB2, the subunits of RNA polymerase II, are essential for stomatal patterning and differentiation. NRPB3 receives signals from transcription factors during stomatal patterning development by directly interacting with FAMA and ICE1. This mechanism is similar to that in muscle cell differentiation (Chen et al., 2016, Development). RNA polymerase II (Pol II) associated proteins (RPAPs) RIMA-QQT1-IYO complex could work together with key stomatal transcription factors, SPEECHLESS, MUTE, FAMA and SCREAM, to drive cell fate transitions in the stomatal cell lineage, providing a novel mechanism by which RPAP proteins may control differentiation of cell types and tissues in eukaryotes (Chen et al., 2021, New Phytologist). Interestingly, we found OsSCR and OsSHR control the initiation of stomatal cell lineage and fomation of subsidiary cell in rice (Wu et al., 2019, New Phytologist). This important discovery attracts the eyes of researchers in stomata development of grasses. Several review papers cited these important findings and intensively dicussed them in the well-known journals including Plant Journal, New Phytologist, and Frontiers in Plant Science in 2020. We also demonstrate FLP plays a role in meristemoid-to-GMC fate transition during stomatal development in Arabidopsis (Li et al., 2023, The Plant Journal). Our current research focuses on the genetic regulation network of stomatal development in maize, rice and other gramineous crops.

3. Crop gene editing breeding. Gene editing and other biotechnologies are used to breed new varieties of maize and rice with high yield and stress resistance.
