Different plant cell types express unique transcriptomes, proteomes, and metabolomes. Therefore, the isolation of specific cell types prior to molecular analyses is important to understand the specification, differentiation, and function of these cells. Isolation of specific plant cell types from composite organs can be achieved by laser microdissection (LMD). A wide variety of methods to fix and embed tissues prior to LMD and downstream molecular analyses have been developed for different plant species and tissues. The present review summarizes and highlights the most recently applied LMD approaches in plant science.
不同的植物细胞类型表达独特的转录组、蛋白质组和代谢组。因此,在进行分子分析之前分离特定的细胞类型对于理解这些细胞的特化、分化和功能很重要。通过激光显微切割(LMD)可以从复合器官中分离出特定的植物细胞类型。针对不同的植物物种和组织,已经开发出了多种在LMD及下游分子分析之前固定和包埋组织的方法。本综述总结并重点介绍了植物科学中最近应用的LMD方法。
