Transcription factors (TFs) regulate gene expressions via interacting with sequences located in the promoter regions and they are classified into ca. 60 families based on their DNA-binding domains. In this study, several recently sequenced cotton genomes were analyzed to identify TF-coding genes for a phylogenetic and comparative structural genomic analysis. Single nucleotide polymorphisms (SNPs) were further identified for homologous TF-coding genes. A genomewide gene expression study will be performed to reveal their regulations associated with abiotic and biotic stresses, fiber development and male fertility in cotton.
