• A Sinorhizobium meliloti collection (1443 strains stored at –80°C) representative of the intraspecific variation in relation to ecogeographic and bioagronomic characteristics of the isolation environments and the genetic diversity of the host plant

• The dairy bacteria collection (  consists mostly of lactic acid bacteria (LAB) isolated from dairy sources but there are also present spoilage and food pathogenic bacteria of dairy interest, as well bacteriophages. This collection represents an important source of biodiversity, as the strains have been isolated over several years from different traditional or industrial dairy products (raw milk, fermented milks, cheeses), geographical areas, and production plants.

• There are about 4300 accessions of forage and grain legumes and forage and turf grasses belonging to 52 species, of which 60% represented by Italian landraces and natural populations, kept under long-term storage as dehydrated seed (7-8% moisture) in sealed bags at –18 °C

• There is a TILLING collection of Medicago truncatula (estimated mutation rate of 1 mutation/kbp/400 plants) including about 2000 M2 plants for which DNA and M3 seed are available
