Verticillium dahliae JR2 Assembly and Gene Annotation

About Verticillium dahliae JR2

Verticillium dahliae is a fungal plant pathogen. It causes verticillium wilt in many plant species, causing leaves to curl and discolor. It may cause death in some plants. Over 400 plant species are affected by Verticillium complex.

Assembly

The draft genome sequence of the JR2 strain was assembled by the Laboratory of Phytopathology, Wageningen University, using 250X coverage PacBio and optical mapping solved using MapSolve. The assembly has been submitted to the INSDC archives as GCA_000400815.2.

Annotation

Protein coding gene annotation was generated by the Laboratory of Phytopathology, Wageningen University. The genome was annotated using Maker2 software supported by RNA-seq reads, assembled RNA-seq data that were used as EST evidence, 35 different fungal proteomes and two ab-intio gene predictors (Augustus and SNAP). The predicted genes were manually curated using WebApollo software.

The set of non-coding RNA genes available comprises a set of gene models [annotated by the Laboratory of Phytopathology, Wageningen University, plus an additional set annotated using tRNAScan-SE (Lowe, T.M. and Eddy, S.R. 1997), RFAM (Griffiths-Jones et al 2005), and RNAmmer (Lagesen K.,et al 2007); additional analysis tools have also been applied.

Expression Data

RNA-seq expression data of Verticillum dahliae strain JR2 infecting Nicotiana benthamiana at 4, 8, 12 and 16 days post inoculation were mapped to the genome using Tophat2 software by Laboratory of Phytopathology, Wageningen University. This data can be viewed as a track in the browser.

Variation

The variation data was provided by the Laboratory of Phytopathology, Wageningen University, by calling SNPs from 10 resequenced strains aligned to the Verticillium dahliae JR2 reference strain.
