OsMYB4-Regulated Transcriptional Network of Rice

ABSTRACT: The OsMyb4 transcription factor of rice represents a more recent example of a regulatory gene used in various attempts to develop stress-tolerant crops by regulon engineering. Although OsMyb4 confers tolerance to low temperature and drought by affecting the biosynthesis of compatible osmolytes and the phenylpropanoid metabolic process, the exact composition and scope of the OsMyb4 network has not been established from the previous analysis of heterologous overexpression in Arabidopsis. Further characterization of the OsMyb4 regulon at the global scale will facilitate understanding of the intricate underpinnings of a pathway independent of the DREB/CBF network. To dissect the OsMyb4 network of rice in relation to chilling stress response mechanisms, we conducted a gene expression profiling
