*A total of 291 putative transcription factor genes from cluster 5, 8, and 10 were categorized based on functional domains. The distribution as frequencies of occurrence was presented in column 2. *P values were calculated in hypergeometric distribution analysis as the following: The proportion of transcription factors of a given class was compared with the proportion of that class in the whole set of transcription factors. AOPBP, ascorbate oxidase promoter-binding protein. SREBP, sucrose-responsive element binding factor. The classification of the transcription factors can be found at http://mtgea.noble.org/
