The genome of the plant-parasitic and virus vector nematode Xiphinema index
The dagger nematode Xiphinema index (Thorne & Allen, 1950) is a migratory ectoparasite that transmits specifically the GFLV to the grapevine during its feeding. The GFLV has a huge economic impact on the high added value wine industry. Although multiple genomes are available in Tylenchoidea and Aphelenchoides, no reference genome is available for a representative of the Longidoridae despite their economic importance and their interesting phylogenetic position as a distant and early-branching clade. Therefore a high-quality genome of X. index is required to address multiple questions in regard to genome structural organization as much as the repertoire of genes involved in interaction processes.  We propose to combine long reads obtained by single-molecule high-fidelity (PacBio HiFi) sequencing technology, and long-range connectivity information for de novo assembly at chromosome scale from an isogenic X. index strain.
