Welcome to Transcription Factor Database

GrassTFDB provides a comprehensive collection of transcription factors from maize, sugarcane, sorghum and rice. Other grasses will be included as sequence information becomes available. Transcription factors, defined here specifically as proteins containing domains that suggest sequence-specific DNA-binding activities, are classified based on the presence of 50+ conserved domains. Links to resources that provide information on mutants available, map positions or putative functions for these transcription factors are provided. Transcription factors are being named using a standard nomenclature that will simplify references to them as well as comparative analyses between the grasses.
