Diverse Roles of MAX1 Homologues in Rice.

Cytochrome P450 enzymes encoded by ()-like genes produce most of the structural diversity of strigolactones during the final steps of strigolactone biosynthesis. The diverse copies of in provide a resource to investigate why plants produce such a wide range of strigolactones. Here we performed in silico analyses of transcription factors and microRNAs that may regulate each rice , and compared the results with available data about expression profiles and genes co-expressed with genes. Data suggest that distinct mechanisms regulate the expression of each . Moreover, there may be novel functions for homologues, such as the regulation of flower development or responses to heavy metals. In addition, individual could be involved in specific functions, such as the regulation of seed development or wax synthesis in rice. Our analysis reveals potential new avenues of strigolactone research that may otherwise not be obvious.
