Heterobasidion spp, triggers non-specific defence responses in bark of Norway spruce
Norway spruce [Picea abies (L.) Karst.] is one of the economically most important conifer species in Europe. The major pathogen on Norway spruce is Heterobasidion parviporum (Fr.) Niemelä & Korhonen. The completed genome sequence of H. irregulare opens up new possibilities to understand the interactions between Heterobasidion spp. and spruce. However to date there are no completed genome sequen...
متن کاملDefense-related genes expressed in Norway spruce roots after infection with the root rot pathogen Ceratobasidium bicorne (anamorph: Rhizoctonia sp.).
To study the mechanisms of inducible disease resistance in conifers, changes in transcript accumulation in roots of Norway spruce (Picea abies (L.) Karst.) seedlings exposed to the root rot pathogen Ceratobasidium bicorne Erikss. and Ryv. (anamorph: Rhizoctonia sp.) were monitored by differential display (DD). Because C. bicorne attacks root tips, a desiccation treatment was added to exclude ge...
متن کاملEvolutionary history of the conifer root rot fungus Heterobasidion annosum sensu lato.
We investigated two hypotheses for the origin of the root rot fungus Heterobasidion annosum species complex: (i) that geology has been an important factor for the speciation (ii) that co-evolutionary processes with the hosts drove the divergence of the pathogen species. The H. annosum species complex consists of five species: three occur in Europe, H. annosum s.s., Heterobasidion parviporum and...
متن کاملUnderstanding virulence of Heterobasidion annosum s.l., a root rot pathogen of conifers
Heterobasidion annosum sensu lato (s.l.) species are destructive pathogens causing root and butt rot in conifers. The species complex consists of five species: H. annosum sensu stricto (s.s.), H. abietinum, H. parviporum, H. irregulare and H. occidentale. The aim of this thesis was to improve the understanding of fungal virulence in this species complex. The comparison of H. irregulare and H. o...
متن کاملHeterobasidion root rot in forests on former agricultural lands in Poland: Scale of threat and prevention
This paper describes the specifics of forests on former farmlands in Poland and their protection as well as preventive measures taken. The review refers to polish literature on the threat by root rot caused by Heterobasidion annosum (Fr.) Bref. to pine and spruce plantations established on postagricultural lands on an area of more than 1400 000 ha. In Europe, the latter presents an outstanding ...
