　　研究方向

　　Research Interests

　　1、 細(xì)胞分裂素和生長素相互作用 Auxin/cytokinin interactions

　　生長素和細(xì)胞分裂素是調(diào)控植物發(fā)育的兩類重要激素，其比例和相互作用決定著細(xì)胞生長和分化的命運(yùn)。我們用分子遺傳學(xué)等相關(guān)技術(shù)研究細(xì)胞分裂素如何影響生長素生物合成及極性運(yùn)輸進(jìn)而調(diào)控植物的生長發(fā)育。

　　Auxin and cytokinin are the two classic plant hormones playing pivotal roles in plant development. It is a famous theme in plant science that the development of cells into roots or shoots is often determined by the ratio of auxin/cytokinin. We use molecular genetics to studies how cytokinin regulates auxin biosynthesis and its polar transport to influence plant development.

　　2. 生殖細(xì)胞發(fā)育 Germ cell development

　　植物的有性生殖涉及減數(shù)分裂（孢子發(fā)生）和配子體（花粉）發(fā)育，受多個(gè)基因調(diào)控并需要細(xì)胞間的通訊和相互協(xié)調(diào)。我們主要用擬南芥為材料分離突變體，用分子生物學(xué)手段研究大小孢子發(fā)生及其配子體發(fā)育的分子機(jī)理。

　　Sexual reproduction in plants occurs via meiosis (sporogenesis) and gametophyte development under strict genetic control with highly coordination between cells. We use the current powerful tools in cell and molecular biology to study the related molecular mechanisms through isolating mutants in Arabidopsis and cloning the corresponding genes.
