Abstract:

?生长发育是一个复杂的动态过程,了解其发生细节是生命科学研究的重要内容。最新发展起来的微流芯片技术为实现这个目标提供了新的途径。动物及微生物中的应用表明,该技术兼有实时定量监测和高通量整合处理的优势。在植物研究领域,用针对根生长特点和要求设计的根微流芯片结合荧光共振能量转移探针已经成功地检测出拟南芥(Arabidopsisthaliana)根细胞内葡萄糖和游离的Ca2+、Zn2+的浓度。随着各种底物特异的荧光共振能量转移探针的开发和应用,根微流芯片还可以用来检测植物细胞内激素或其它代谢中间产物的浓度及其动态变化过程。不仅如此,以微流芯片为基础发展起来的PlantChip和TipChip则为研究植物与微生物的相互作用以及植物花粉管极性生长和细胞分裂分化提供了理想的平台。作为了解遗传因素或环境刺激导致细胞生命活动变化细节的有力工具,微流芯片技术有望为植物研究领域带来更多新的进展和突破。
