Current study of Dutch elm disease causal agent in the Czech Republic

Popis výsledku v původním jazyce

Dutch elm disease caused by Ophiostoma ulmi (Buism.) Nannf. is present in the Czech republic since 1932. Presence of a new aggressive species O. novo-ulmi Bras. was revealed in 2006 by means of PCR. Up to now we have recorded both O. novo-ulmi subspecies- novo-ulmi and americana and their very frequent hybrids by means of PCR-RFLP in two gene regions. 13 czech strains were more particularly described from the point of view of cerato-ulmin production, mating type and vegetative compatibility type. Striking peculiarity is a strain M9 which doesn't produce any cerato-ulmin, although it was isolated from a tree with typical DED-symptoms. This strain is probably d-infected. One subspecies hybrid strain (M13) was used for infection tests on two DED-resistant elm hybrids. It was inoculated into 10 years old trees, and it caused high defoliation of hybrid 'Groeneveld' and low defoliation on hybrid 'Dodoens'.
