科研领域描述
本实验室主要兴趣在于:
  植物超长链脂肪酸合成途径的研究。
  脂质代谢途径调控棉花纤维发育的分子机制研究。
  棉花脂质组学研究  
  脂肪酸是指一端含有一个羧基的长的脂肪族碳氢链,在生物体内大部分脂肪酸都以脂质形式存在。超长链脂肪酸是指碳骨架长度超过20个碳原子的脂肪酸,在植物体内这类脂肪酸主要集中于细胞膜鞘脂及植物表面蜡质中,其生物学作用不很清楚。
  实验室近几年来以陆地棉和无长绒无短绒突变体为实验材料,通过构建大规模棉花转录组基因芯片,分离、鉴定和研究棉花纤维伸长相关基因。其中,超长链脂肪酸(VLCFA)合成途径是被鉴定为一条重要的在纤维发育期显著上调的代谢途径,我们克隆并鉴定编码3-酮脂酰-CoA合酶、3-酮脂酰-CoA还原酶及烯酰-CoA还原酶的棉花cDNA。为验证其生物学功能,将它们互补相对应的酵母突变体中,并使用气相色谱质谱联用仪对互补棉花基因的酵母突变体中的脂肪酸进行定性和定量分析,研究发现VLCFA通过激活乙烯合成途径不仅能够促进棉纤维伸长发育,而且还能促进拟南芥茎细胞伸长。这是关于VLCFA可能作为植物信号分子的首次报道,对于VLCFA如何调控植物发育的进一步研究具有重要意义。利用超高效液相色谱质谱联用(ESI-MS/MS)技术,对六类棉纤维中的甘油磷脂建立了共计1566对离子对的脂质组学MRM检测方法。提取开花后10天(10 dpa)野生型陆地棉纤维、胚珠及无毛突变体(fuzzless-lintless)中的总脂质。实验结果表明,10 dpa纤维细胞中磷脂酰肌醇PI34:3的含量明显高于胚珠及无毛突变体中的含量,其中脂肪酸链组成是棕榈酸C16:0和亚麻酸C18:3。在胚珠体外培养实验中,外源施加包含C18:3的PI或C18:3均能够显著促进纤维细胞的伸长。磷脂酰肌醇合酶PIS抑制剂5-Hydroxytryptamine抑制纤维细胞伸长。病毒诱导的基因沉默实验结果表明,抑制GhPIS导致显著的纤维变短表型。
