Examination of Oomycota diversity of Karabakh based on herbarium specimens

Summary

The information presented in the article is based on the examination of specimens residing to Oomycota phylum of fungi-like organisms collected by a number of researchers from Karabakh territory in different years and kept in the herbarium (BAK), as well as relevant literature data. The samples were inspected, the taxonomic structure of the fungi, and their host plants were determined. Research objects consist of 50 species of the genera Albugo (Pers.) Roussel, Wilsoniana Thines of the family Albuginaceae and Bremia Regel, Hyaloperonospora Constant., Peronospora Corda, Plasmopara J. Schröt and Pustula Thines of the family Peronosporaceae. These fungi were found on 58 plant species belonging to 15 orders, 22 families, and 48 genera. These plants include 27 annual, 20 perennial, four (Alyssium alyssoides L., Lactuca seriola L., Melilotus officinalis (L.) Desrsh, Trifolium alpestre L.) annual or biennial, one (Brassica oleraceae L.) is annual or perennial, three biennial herbs (Barbarea vulgaris subsp. arcuata (Opiz ex J. Presl & C. Presl.) Čelak., Conium maculatum L., Hyosciamus niger L.), one liana (Vitis vinifera L.) and two shrubs (Artemisia gmelini Weber ex Stechm., Capparus spinosa L.). It should be noted that the species of fungi belonging to this group are pathogenic and cause diseases of a number of cultivated plants as well as wild plants.
