Pigeonpea (Cajanus cajan L.), a diploid legume crop, is a member of the tribe Phaseoleae. This tribe is located in the millettioid (tropical) clade within the subfamily Papilionoideae, which includes many important legume crop species such as soybean (Glycine max), cowpea (Vigna ungiculata), common bean (Phaseolus vulgaris) and mung bean (Vigna radiata). It plays important role in food and nutritional security because it is a rich source of proteins, menerals and vitamins.

The first draft of  Pigeonpea genome sequence published by  (Singh, N.K. et al. 2011) and given us an opportunity to develop a comprehensive transcription factors (TF) database, called Pigeonpea Transcription Factors Database (PpTFDB) using various computational methods. PpTFDB is the first online comprehensive TF database developed for the legume crop Pigeonpea L. (Cajanus cajan). This database contains a set of 1829 predicted TFs (Gene models) and classifies them into 55 TF families. In addition, this database provides comprehensive information at both family and gene level. At family level, this database provides description about the family, list of predicted TFs, for entire TF family. At gene level, this database provides physical location, sequences (Protein, CDS and Genomic sequences), functional annotation (by InterProScan), protein physical properties, mined SSRs along with their primers information and percentage orthology with other legume crops. This database is user friendly and also provides the researchers to download the entire data used to build the database freely.
