Plant development is controlled by both endogenous genetic programs and responses to exogenous signals. Microarray experiments are being used to identify the genes involved in these developmental processes. Most of the analyses conducted to date have been conducted on whole organs. Although these studies have provided valuable information, they are limited by the composite nature of plant organs that consist of multiple cell types. Technical advances that have made it possible to study global patterns of gene expression in individual cell types promise to increase greatly the information revealed by microarray experiments.

全局表达谱分析适用于植物发育。

植物的发育既受内源遗传程序控制，也受外源信号响应的控制。微阵列实验正在用于鉴定参与这些发育过程的基因。迄今为止，大多数分析都是在整个器官上进行的。尽管这些研究提供了有价值的信息，但它们受到包含多种细胞类型的植物器官的复合性质的限制。技术进步使研究单个细胞类型的整体基因表达模式成为可能，有望大大增加微阵列实验揭示的信息。
