The Plant Promoter Database (PPDB) uses word frequency analysis to identify 8 base-pair motifs in promoters. Motifs are categorized as TATA-box, Y-patch (a CT-rich region often found in plant TATA box promoters), the initiator near the transcription start site, and cis-regulatory motifs. The regulatory motifs are a group of 308 8 base-pair sequences which are used to represent regulatory sites.
References (for PPDB):PPDB_MPSS | The Plant Promoter Database (PPDB) also deposits the data of transcription start sites (TSSs) detected by the CT-MPSS method. The CT-MPSS method is a combination of cap trapper (CT), a reliable method for preparing the 5' end of full-length cDNA, and massively parallel signature sequencing (MPSS), which enables ultra-parallel sequencing in a considerably shorter time and at lower cost than conventional sequencing methods. |
