我们课题组主要研究植物Na⁺,K⁺/H⁺反向转运蛋白在植物生长发育中的功能。Na⁺,K⁺/H⁺反向转运蛋白的生化活力是跨膜转运Na⁺或K⁺，同时反向交换质子（H⁺）。因此，Na⁺,K⁺/H⁺反向转运蛋白在维持细胞离子和pH稳态平衡方面起着重要作用。拟南芥基因组含有大量的Na⁺,K⁺/H⁺反向转运蛋白，可以分为三个亚家族，即NHXs，CHXs和KEAs。我们以拟南芥和酵母作为模型生物系统，重点研究NHX和KEA基因家族的离子转运活性和生理功能。我们的研究目标是揭示NHX和KEA在Na⁺和K⁺转运，pH平衡，膜微囊运输，耐盐胁迫以及植物生长发育等过程中的生物功能。

Our group is interested in exploring the role of Na⁺,K⁺/H⁺ antiporters in plants. The biochemical function of the Na⁺,K⁺/H⁺ antiporter is to transfer the Na⁺ or K⁺ across a membrane in exchange for protons (H⁺). The Na⁺,K⁺/H⁺ antiporter thus is crucial for cellular ion and pH homeostasis. The Arabidopsis genome has a large Na⁺,K⁺/H⁺ antiporter family that contains three subfamilies: NHXs, CHXs and KEAs. Using Arabidopsis and yeast as model systems, we are focusing on characterizing the ion transport activity and physiological function of the NHX and KEA gene families. We aim to investigate their roles in Na⁺ and K⁺ transport, pH homeostasis, membrane trafficking, salt tolerance, and the regulation of growth and development.
