Functional analysis of H(2)O(2)-generating systems in Botrytis cinerea: the major Cu-Zn-superoxide dismutase (BCSOD1) contributes to virulence on French bean, whereas a glucose oxidase (BCGOD1) is
SUMMARY The oxidative burst, a transient and rapid accumulation of reactive oxygen species (ROS), is a widespread defence mechanism of higher plants against pathogen attack. There is increasingExpand
Polygalacturonase is a pathogenicity factor in the Claviceps purpurea/rye interaction.
Claviceps purpurea is a biotrophic, organ-specific pathogen of grasses and cereals, attacking exclusively young ovaries. We have previously shown that its mainly intercellular growth is accompaniedExpand
Infection Strategies of Botrytis cinerea and Related Necrotrophic Pathogens
Botrytis cinerea Persoon: Fries (known as “grey mould fungus”) causes serious preand post-harvest diseases in at least 235 plant species (Jarvis, 1977), including a range of agronomically importantExpand
Identification and characterization of genes from Streptomyces sp. strain K30 responsible for clear zone formation on natural rubber latex and poly(cis-1,4-isoprene) rubber degradation.
Streptomyces sp. strain K30 was isolated from soil next to a city high way in Münster (Germany) according to its ability to degrade natural and synthetic poly(cis-1,4-isoprene) rubber and to formExpand
Functional analysis of an extracellular catalase of Botrytis cinerea.
Summary There is evidence that the necrotrophic fungal pathogen Botrytis cinerea is exposed to oxidative processes within plant tissues. The pathogen itself also generates active oxygen species andExpand
Claviceps species are the causal agents of the ubiquitous ergot disease. About thirty-six different filamentous fungi constitute this genus of phytopathogenic ascomycetes. They parasitize more thanExpand
The contribution of cell wall degrading enzymes to pathogenesis of fungal plant pathogens
The plant cell wall functions as a barrier to biotic and abiotic agents. Plant pathogenic bacteria and fungi produce cell wall degrading enzymes (CWDEs) which are believed to degrade this barrier,Expand
CPMK2, an SLT2‐homologous mitogen‐activated protein (MAP) kinase, is essential for pathogenesis of Claviceps purpurea on rye: evidence for a second conserved pathogenesis‐related MAP kinase cascade
Cpmk2 , encoding a mitogen‐activated protein (MAP) kinase from the ascomycete Claviceps purpurea , is an orthologue of SLT2 from Saccharomyces cerevisiae , the first isolated from a biotrophic,Expand
Structure and expression of two polygalacturonase genes of Claviceps purpurea oriented in tandem and cytological evidence for pectinolytic enzyme activity during infection of rye
Two putative polygalacturonase (PG) genes were isolated from strain T5 of Claviceps purpurea, using the pgall gene of Aspergillus niger as a probe. The two genes (pg1 and pg2) are closely linked andExpand
