Banana Genome Hub and MGIS : Managing Banana Germplam Data in the NGS Era

Since the release of the Musa acuminata reference genome sequence in 2012 (D’Hont et al, 2012), a significant number of new OMICS datasets have been generated, including the improvement of the reference DH Pahang, new genomes, transcriptomics etc.

This presentation intends to show how all those datasets have been regularly inserted into the Banana Genome Hub (BGH) and the Musa Germplasm Information Systems (MGIS). BGH handles version 1 and 2 of the assembly (Martin et al, 2016) and additional Musa species or subspecies. Moreover, 17 libraries from 8 transcriptomics studies were included in JBrowse and mapped on the version 2 of the assembly. Repeat elements classified by types were also recently added. SNPs makers issued from a GWAS study (Sardos et al, 2016) can be visualized using the multivariant JBrowse extension and on a dedicated page for diversity studies providing interactive gene tree viewer. Publications related on banana germplasm are now tracked in MGIS allowing at a glance to see what has been already done for a particular genotype. Finally, SNP data from GBS data can be queried and filtered on 105 accessions using the GIGWA applications (Sempere et al, 2016) embedded in MGIS. Finally, the presentation will demonstrate the interoperability of information systems to support genomics of genebanks.
