Databases of Transcription Factors in Legumes

In plants, sequence-specific DNA-binding transcription factors (TFs) are key molecular switches that control a wide range of biological processes from plant growth and development to responses to environmental stimuli. The availability of the whole genome sequences of several legume species, such as soybean (Glycine max), Lotus japonicus, and Medicago truncatula, has enabled the research community to carry out large-scale data mining to identify and annotate their TF repertoires for functional and comparative genomics. Individual TF and its families with relevant information including sequence and domain features, predicted tertiary structures, domain alignments, gene ontology assignment and sequence comparison; information on the available full-length cDNAs, identity, and positions of all types of known cis-motifs found in the promoter regions, gene expression are accessible at species-specific and/or integrative TF databases.
