Plant microarray for gene expression profiling and their application

Microarray can parallel quantification of large numbers of genes and promises to provide detailed insight into cellular processes involved in the regulation of gene expression. In plants, microarray for gene expression profiling should provide an important way for understanding of gene functions and signaling networks that operate plants growth and development, respond to biotic and abiotic stresses, important agronomic characters. This review focuses on the application of microarray for gene expression profiling in plants. Moreover, development and application of tobacco microarray is also summarized. This review will provide useful information for better application of plant microarray in studies of gene function and regulation mechanism.
