Czech Collection of Phytopathogenic oomycetes

Keywords: oomycetes – PhytophthoraPythium – phytopathogenic – Czech Republic – RILOG

The collection was established based on the framework of Scientific Intent No MZP0002707301 in 2005 and was admitted in 2012 as a member of The National Programme on Conservation and Utilization of Genetic Resources of Microorganisms (NPGZM) (Czech). 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.).

There are approx. 447 strains of approx. 39 oomycetous taxa preserved which are belonging to Phytophthora (26 strains) and Pythium (13 strains) in the accessible part of the collection. The other 400 strains are deposited in the private 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 Hrabětová (molecular determination) and Liliya Fedusiv (technician).
