Bottom Line: For 14 plant species with emerging or complete genome sequence, PlantGDB's genome browsers (xGDB) serve as a graphical interface for viewing, evaluating and annotating transcript and protein alignments to chromosome or bacterial artificial chromosome (BAC)-based genome assemblies.Annotation is facilitated by the integrated yrGATE module for community curation of gene models.PlantGDB also hosts a plant genomics research outreach portal (PGROP) that facilitates access to a large number of resources for research and training.

ABSTRACT
PlantGDB (http://www.plantgdb.org/) is a genomics database encompassing sequence data for green plants (Viridiplantae). PlantGDB provides annotated transcript assemblies for >100 plant species, with transcripts mapped to their cognate genomic context where available, integrated with a variety of sequence analysis tools and web services. For 14 plant species with emerging or complete genome sequence, PlantGDB's genome browsers (xGDB) serve as a graphical interface for viewing, evaluating and annotating transcript and protein alignments to chromosome or bacterial artificial chromosome (BAC)-based genome assemblies. Annotation is facilitated by the integrated yrGATE module for community curation of gene models. Novel web services at PlantGDB include Tracembler, an iterative alignment tool that generates contigs from GenBank trace file data and BioExtract Server, a web-based server for executing custom sequence analysis workflows. PlantGDB also hosts a plant genomics research outreach portal (PGROP) that facilitates access to a large number of resources for research and training.

PlantGDB is accessible at http://www.plantgdb.org, and genome browsers are accessible at http://www.plantgdb.org/XxGDB, where Xx is the first letter of the genus and species (e.g. AtGDB = Arabidopsis thaliana genome database).

Mentions: PlantGDB periodically uploads and parses all Viridiplantae sequences from GenBank (3) and Uniprot (4) into ∼70 000 individual data sets according to species or subspecies origin (Figure 1). PlantGDB's sequence data are refreshed approximately every 4 months, coinciding with alternate bimonthly GenBank version releases. GenBank and Uniprot sequences are uploaded, parsed by (sub)species, indexed for BLAST (5) and GeneSeqer (6) analysis, and loaded into MySQL tables. For all species with >10 000 published transcripts, a non-redundant set of PlantGDB-generated Unique Transcripts (PUTs) is generated using a custom assembly pipeline (http://www.plantgdb.org/prj/ESTCluster/PUT_procedure.php). PUTs are aligned to UniProt entries using BLAST, and the best matches (if any) and UniProt-associated Gene Ontology (GO) annotations (7) are stored. Currently, 116 species have PUT assemblies at PlantGDB, spanning diverse taxonomic groups (Figure 2). Users can track assembly progress in PlantGDB at http://www.plantgdb.org/prj/ESTCluster/progress.php. PlantGDB also provides genome survey sequence (GSS) assemblies for maize and sorghum (http://www.plantgdb.org/prj/GSSAssembly/). All PlantGDB sequence data (raw and processed) are available for download in a variety of file formats at http://www.plantgdb.org/download/download.php. In addition, all Zea mays sequence data at PlantGDB are uploaded monthly to MaizeGDB, the central repository for maize genetic information (http://www.maizegdb.org) (8).Figure 1.
