Grapevine Genomes

Grapevine Genomes

An overview of PN40024 genomics resources

The five different genome assemblies of PN40024 are shown below, together with their de novo annotations. Transfers from previous annotations to newer assemblies are also shown, as these transferred annotation files are commonly used in the community. It also becomes relevant to understand to which genomes these annotations belong to. The PN40024 downloads section centralises access to files and clarifies their nature. Scroll down for further descriptions of the different grapevine genomes and their available resources.

PN40024.T2T (v5)

The Genome browser contains reference and alternative (heterozygous, ALT) chromosomal regions of the T2T assembly, plus a chr00 with all unanchored contigs. It also contains accurate mapping of all previous gene annotations (using Liftoff on copies mode), together with mapped long-read (Iso-seq) and short-read (Illumina) sequencing data, which was generated from vegetative and reproductive organs of PN40024 at different developmental stages. This RNA-seq data was kindly provided by Daniela Holtgräwe (Bielefeld University · CeBiTec), Camille Rustenholz (University of Strasbourg · INRAE Colmar) and Doreen Ware (Cold Spring Harbour Laboratory).

Assembly: The PN40024.v4 assembly is based on the Sanger scaffolds of the 12Xv2 version that were corrected, extended and completed using 30X PacBio data. The heterozygous regions are better identified (Velt et al. 2023).

European Nucleotide Archive: The genome assembly can be also accessed at ENA.

Annotation: The PN40024.v4 annotation is based on a mixed approach, derived from de novo annotation and matching with the previous structural annotation version. In an effort to preserve VCOST.v3 gene IDs where possible (e.g. in cases where chromosome numbers are unchanged) a reciprocal best-hits strategy between VCOST.v3 and PN40024.v4.1 annotations was carried out. This allowed the transfer of 67% of VCOST.v3 gene IDs. In general, the new de novo annotation performed better than the previous annotation in terms of BUSCO stats.

The current version is v4.3, released after Integrape Annot’Training School for gene model manual curation. 

To indicate possible matches between the current annotation and previous versions (see overview above), a feature-overlap strategy was carried out to work out id correspondences between all annotation versions associated to PN40024.v4 (40X) which includes previous annotations (8x, NCBI, v0, v1, v2, v3) remapped using Liftoff and the most up to date v4.3 annotation.

PN40024 12X.2 Assembly (URGI)

Assembly: The 12Xv2 chromosome assembly is based on the scaffolds of the grapevine reference genome build (FN594950-FN597014, EMBL release 102; Vitis vinifera cv. PN40024).

Further information about the 12Xv2 can be found at URGI (as well as original genome and annotation files).

The most up to date VCost.v3 annotation file shared in Grapedia also includes the reference gene catalogue (v2) symbols in the “Name=” field. Please access the catalogue and gene cards section to submit gene names to the catalogue (a recording of the online workshop is available) or to explore the expression of your genes of interest in VitViz.

The PN40024 reference assembly (12Xv2) is also hosted at Grapegenomics and is equiped with a blast server. The site is actively maintained by the CantuLab at the University of California, Davis. 

Other wine grape cultivar and Vitis species assemblies/annotations

Additional genomes of different cultivars, subspecies and species of the Vitis genus are also hosted at Grapegenomics, and include several chromosome-scale phased assemblies.
