微矩陣是近年來分子生物學常使用的研究工具，目前已被廣泛用於許多不同物種。各種不同形式的微矩陣中，以DNA微矩陣最為常見。由於具有可以大量觀察基因表現的特性，DNA微矩陣經常被用來記錄整個轉錄體變化的情形。隨著其他實驗技術的進步，微矩陣也可以與各種新興技術如次代定序、生物資訊學等配合使用，更加深描繪及解釋生理現象的能力。本文回顧微矩陣技術之原理及目前在植物研究的主要應用方向，並討論目前使用於林木生理之相關研究。

Microarray has been used as a tool in molecular biology research for many species. Many different types of microarray are available, however, DNA microarray is the most popular array that is being used in many studies. With the ability to observe many genes’ expression, DNA microarray has been used to evaluate transcriptomic variations. Through the advance of other technologies such as next-generation sequencing and bioinformatics, microarray can be coupled with other tools to improve capability of transcriptome profiling and analysis. This review discusses the principle of microarray, its main direction in plant research and related researches in forest tree physiology.
