  Czech Collection of Phytopathogenic Oomycetes

Collection

•    History
The collection was established in 2005 under the leadership of Karel Cerny and was admitted in 2012 as a member of The National Programme on Conservation and Utilization of Genetic Resources of Microorganisms.

•   Characterization of collection
There are approx. 312 strains of approx. 29 oomycetous taxa preserved which are belonging to Phytophthora and (23 taxa) Pythium (6 taxa) in the accessible part of the collection. The other 400 strains are deposited in the non-public section of the collection. The isolates were acquired from many various plant hosts including forest, ornamental, and fruit trees as well as other hosts from various other environments (riparian and forest stands, parks, urban greenery, orchards, public gardens, gardening centres, ornamental and forest nurseries etc.). The collection is operated by Marcela Mrázková (custodian), Markéta Hejná (molecular determination) and Liliya Fedusiv (technician).

•    Methods of conservation
Individual isolates are maintained on agar slants (OA agar) in vials in a refrigerator at a temperature of about 12 ° C in four tubes. Their condition is regularly monitored and the strains are regularly re-inoculated at intervals of 1-2 years.

Application:

The collection aims for the preservation of genetic diversity of important phytopathogenic and other oomycetes in the Czech Republic for scientific and other purposes (tests of pathogenicity and host resistance, testing and development of control measurements, reference studies in science and phytosanitary services, systematics, education, etc.)
