研究方向

1 ）油菜素內酯的信號傳遞、合成、及代謝途徑的分子調控機制 (Brassinosteroid Signal Transduction and Homeostasis): 油菜素內酯是一類重要的植物激素，參與調控植物生長的各個階段，阻斷油菜素內酯的生物合成或信號轉導都會使植物變得極其矮小，并表現出雄性不育、推遲衰老、在黑暗培養時呈現出去黃化等的異常表型。油菜素內酯的受體是一個跨膜的亮氨酸富集型受體激酶，它的胞外特定結構域能特意與油菜素內酯相互作用從而啟動胞內一系列磷酸化、脫磷酸化反應，把信號一步步傳到細胞核中，最終改變基因的表達。在過去的十年中，本研究小組利用激活標簽遺傳學手段成功地分離到多個關鍵蛋白 ( 比如： BRS1 ， BAK1 ， AtSERK1 ， BRL1 ， BRL3 ， BEN1 等 ) ，研究表明它們參與油菜素內酯的信號轉導、合成、及代謝調控。利用經典遺傳學及生物化學手段，本實驗室清楚地證明了BAK1在油菜素內酯信號早期階段起必不可少的作用。現階段的工作集中在利用遺傳、生化、蛋白組學等方法繼續發現參與油菜素內酯信號轉導、合成、及代謝調控的新蛋白，并對以往實驗室已發現蛋白所參與的具體作用機制作深入細致的探討。同時，我們也密切關注不同植物激素之間通過互作來調控植物的生長發育及逆境適應的分子機理。

2 ）用遺傳及生化手段研究擬南芥中一類亮氨酸富集型受體蛋白激酶的生物學功能 (Functional Analyses of LRR-RLKs): 細胞與細胞之間的信號轉導是高等植物生長發育的細胞生物學基礎，受體激酶在信號轉導過程中起至關重要的作用，它們通常作為信號轉導的原初受體。過去的十幾年中本實驗室做了大量的前期工作，克隆了擬南芥基因組中全部223個編碼亮氨酸富集型受體蛋白激酶的大多數全長 cDNA ，克隆并建立了全部223個LRR-RLK的promoter-GUS轉基因植株，對它們在不同發育階段的組織水平的轉錄表達進行了詳細的研究，對進一步了解它們真正的生物學功能奠定了良好的基礎。目前本實驗室正在利用各種遺傳學、分子生物學及組學手段對223LRR-RLKs中尚未揭示功能的分子開展生物學功能研究，已有多個尚未研究過的LRR-RLKs的功能被鑒定到，它們的具體分子機理正在研究之中。

3 ）受體激酶介導的植物細胞凋亡的分子機理 (RLK-Mediated Plant Cell-Death Control): 我們前面的工作已發現受體激酶 BAK1 及 BKK1 能同時參與正向調控油菜素內酯信號轉導，同時抑制細胞凋亡，同時敲除 BAK1 和 BKK1 使植物變得極其矮小，并在光下很快進入細胞凋亡過程，造成葉片快速死亡。我們目前正在對 BAK1 及 BKK1 調控細胞凋亡的分子機理作深入的探索。通過傳統遺傳學手段，我們已發現了多個能抑制雙突變體bak1 bkk1細胞死亡的遺傳抑制子，它們的具體作用機制還在研究中。
