Assembled genomic and tissue-specific transcriptomic data resources for two genetically distinct lines of Cowpea ( (L.) Walp).

Cowpea ( (L.) Walp) is an important legume crop for food security in areas of low-input and smallholder farming throughout Africa and Asia. Genetic improvements are required to increase yield and resilience to biotic and abiotic stress and to enhance cowpea crop performance. An integrated cowpea genomic and gene expression data resource has the potential to greatly accelerate breeding and the delivery of novel genetic traits for cowpea. Extensive genomic resources for cowpea have been absent from the public domain; however, a recent early release reference genome for IT97K-499-35 (  v1.0, NSF, UCR, USAID, DOE-JGI, http://phytozome.jgi.doe.gov/) has now been established in a collaboration between the Joint Genome Institute (JGI) and University California (UC) Riverside. Here we release supporting genomic and transcriptomic data for two transformable cowpea varieties, IT97K-499-35 and IT86D-1010. The transcriptome resource includes six tissue-specific datasets for each variety, with particular emphasis on reproductive tissues that extend and support the v1.0 reference. Annotations have been included in our resource to allow direct mapping to the v1.0 cowpea reference. The resource described here is supported by downloadable raw and assembled sequence data.
