Transcription factors are essential for theregulation of gene expression in plant. They are binding toeither enhancer or promoter region of DNA adjacent to the geneand are related to basal transcription regulation, differentialenhancement of transcription, development, response tointercellular signals or environment, and cell cycle control. The mechanism in controlling gene expression of transcriptioncan be understood through the assessment of the completesequence for the maize genome. It is possible that the maizegenome encodes 4,000 or more transcription factors becauseit has undergone whole duplication in the past. Previously,several transcription factors of maize have been characterized. In this review article, the transcription factors were selectedusing Pfam database, including many family members incomparison with other family and listed as follows: ABI3/VP1, AP2/EREBP, ARF, ARID, AS2, AUX/IAA, BES1,bHLH, bZIP, C2C2-CO-like, C2C2-Dof, C2C2-GATA, C2C2-YABBY, C2H2, E2F/DP, FHA, GARP-ARR-B, GeBP, GRAS,HMG, HSF, MADS, MYB, MYB-related, NAC, PHD, andWRKY family. For analyzing motifs, each amino acid sequencehas been aligned with ClustalW and the conserved sequencewas shown by sequence logo. This review article will contributeto further study of molecular biological analysis and breedingusing the transcription factor of maize as a strategy forselecting target gene
