The Institute has four important biorepositories, as a result of decades of activity in the field of plant virology.

  • Virus collection: it is one of the largest in Europe and is made up of more than 120 species of plant viruses from the five continents, collected from the 60s to the present day. Nearly 1000 isolates, strains or accessions are present in the form of  lyophilized leaves and stored at -20 ° C or  at – 80 ° C or as infectious clones.
  • Vineyard-collection: located in Grinzane Cavour (CN), it covers a total area of ​​1.2 hectares and has nearly 700 accessions. In this vineyard there are all the minor local varieties of the North-West of Italy, as well as regional, national and international reference varieties.
  • Collection of antisera: several polyclonal antisera were produced, from the 60s to the present day, for the diagnosis and characterization of different viral species.
  • Collection of reference phytoplasma isolates maintained in vivo (Catharanthus roseus), belonging to different taxonomic groups. This collection is particularly enriched in local phytoplasma isolates belonging to groups 16SrI, 16SrXII and 16SrV.

In addition, the institute is equipped with a collection of higher plants, which includes at least 141 plant species and 270 varieties/cultivars stored as seeds at + 4 ° C.
