How to use Digital Walnut

---

1. About Digital Walnut

Digital Walnut (DW), a comprehensive, fast-growing database, provides a one-stop resource for users to browse, search and download data for researches of Juglandaceae plants transparently. It will play important role in studies of origin and evolution, formation of traits, selection of parents in crossbreeding and oriented genetic improvement of cultivars on walnut and other woody plants.

2. The data of DW database

Digital Walnut housed the most comprehensive high-throughput sequencing data from 13 species and 3 interspecific hybrids.
We collected, screened, and integrated 16 sets of whole genome assembly data and their corresponding annotation information, 322 sets of annotated and searchable reference transcriptomes, combining peer-reviewed published RNA-seq as well as EST datasets, protein sequences, and miRNAs, and one set each of epigenomics and rhizosphere microbial genome data.
