生物化學及生物化學小班讨論課 , 授課 , 北京大學 , 2002年9月-至今
      本實驗室主要興趣在于:
  植物超長鍊脂肪酸合成途徑的研究。
  脂質代謝途徑調控棉花纖維發育的分子機制研究。
  棉花脂質組學研究  
  脂肪酸是指一端含有一個羧基的長的脂肪族碳氫鍊,在生物體内大部分脂肪酸都以脂質形式存在。超長鍊脂肪酸是指碳骨架長度超過20個碳原子的脂肪酸,在植物體内這類脂肪酸主要集中于細胞膜鞘脂及植物表面蠟質中,其生物學作用不很清楚。
  實驗室以陸地棉和無長絨無短絨突變體為實驗材料,通過構建大規模棉花轉錄組基因芯片,分離、鑒定和研究棉花纖維伸長相關基因。其中,超長鍊脂肪酸(VLCFA)合成途徑是被鑒定為一條重要的在纖維發育期顯著上調的代謝途徑,我們克隆并鑒定編碼3-酮脂酰-CoA合酶、3-酮脂酰-CoA還原酶及烯酰-CoA還原酶的棉花cDNA。為驗證其生物學功能,将它們互補相對應的酵母突變體中,并使用氣相色譜質譜聯用儀對互補棉花基因的酵母突變體中的脂肪酸進行定性和定量分析,研究發現VLCFA通過激活乙烯合成途徑不僅能夠促進棉纖維伸長發育,而且還能促進拟南芥莖細胞伸長。這是關于VLCFA可能作為植物信号分子的首次報道,對于VLCFA如何調控植物發育的進一步研究具有重要意義。利用超高效液相色譜質譜聯用(ESI-MS/MS)技術,對六類棉纖維中的甘油磷脂建立了共計1566對離子對的脂質組學MRM檢測方法。提取開花後10天(10 dpa)野生型陸地棉纖維、胚珠及無毛突變體(fuzzless-lintless)中的總脂質。實驗結果表明,10 dpa纖維細胞中磷脂酰肌醇PI34:3的含量明顯高于胚珠及無毛突變體中的含量,其中脂肪酸鍊組成是棕榈酸C16:0和亞麻酸C18:3。在胚珠體外培養實驗中,外源施加包含C18:3的PI或C18:3均能夠顯著促進纖維細胞的伸長。磷脂酰肌醇合酶PIS抑制劑5-Hydroxytryptamine抑制纖維細胞伸長。病毒誘導的基因沉默實驗結果表明,抑制GhPIS導緻顯著的纖維變短表型。
