研究領(lǐng)域: 植物高光效及抗逆性機理 

1. 植物高光效機理及分子改良：深入解析C3植物光合/光呼吸分子調(diào)控機理，充分利用合成生物學(xué)、基因編輯、代謝工程等現(xiàn)代研究技術(shù)，重構(gòu)光合/光呼吸代謝通路，在C3植物中創(chuàng)建新型光合CO2濃縮機制，以期提高作物光合效率、產(chǎn)量及抗逆性。

2. 植物活性氧（ROS）信號調(diào)控分子機理：光合/光呼吸與ROS產(chǎn)生及其信號轉(zhuǎn)導(dǎo)密切相關(guān)。C3植物中70%的H₂O₂源于光呼吸代謝，當(dāng)植物遭遇干旱、高溫、高光等逆境時其占比更高。我們發(fā)現(xiàn)光呼吸關(guān)鍵酶乙醇酸氧化酶（GLO）與過氧化氫酶（CAT）的動態(tài)互作/解離可作為調(diào)控H₂O₂波的一個分子開關(guān)（簡稱GC開關(guān)），這種基于代謝通道原理（metabolic channeling）的物理學(xué)發(fā)生機制尚屬首次報道。目前正致力于深入解析GC開關(guān)調(diào)控的分子機理及其功能，以期為作物抗逆性分子改良提供理論與技術(shù)指導(dǎo)。

3. 植物草酸代謝調(diào)控分子機理：已有大量研究表明草酸在植物抗金屬毒害、耐低磷等過程中起重要作用，但在可食性植物中含量過高會對人與動物產(chǎn)生毒害，因此闡明植物草酸代謝調(diào)控分子機理是合理有效控制草酸積累的前提。通過多年的研究探索，業(yè)已明確草酸代謝與光呼吸乙醇酸/乙醛酸代謝和硝同化緊密關(guān)聯(lián)，目前正致力于進一步解析其代謝通路和分離克隆其代謝調(diào)控的關(guān)鍵基因，旨在最終實現(xiàn)合理有效調(diào)控草酸代謝以提高植物抗逆性的目標(biāo)。
