Secondary metabolites of six Siberian and Crimean Armillaria species and their in vitro phytotoxicity to pine, larch and poplar
Basidiomycetes Armillaria infect deciduous, coniferous and fruit trees, causing enormous economic damage. The role of secondary metabolites (tricyclic sesquiterpene aryl esters - melleolides) in the life cycle and pathogenesis of Armillaria is under active investigation. To date, not all species of...

Basidiomycetes Armillaria infect deciduous, coniferous and fruit trees, causing enormous economic damage.
