Genomic Analysis of the Necrotrophic Fungal Pathogens Sclerotinia sclerotiorum and Botrytis cinerea
Comparative genome analysis revealed the basis of differing sexual mating compatibility systems between S. sclerotiorum and B. cinerea, and shed light on the evolutionary and mechanistic bases of the genetically complex traits of necrotrophic pathogenicity and sexual mating.

New evidence suggests that the pathogen triggers the host to induce programmed cell death as an attack strategy, which could offer new approaches for stable polygenic resistance in future.
Reactive oxygen species in phytopathogenic fungi: signaling, development, and disease.
This review focuses on the role of ROS for fungal virulence and development and indicates that fungi possess superoxide-generating NADPH oxidases similar to mammalian Nox complexes that are important for pathogenicity.
Plant-Symbiotic Fungi as Chemical Engineers: Multi-Genome Analysis of the Clavicipitaceae Reveals Dynamics of Alkaloid Loci
The organization and dynamics of alkaloid loci and abundant repeat blocks in the epichloae suggested that these fungi are under selection for alkaloids diversification, and it is suggested that such selection is related to the variable life histories of the epICHloae, their protective roles as symbionts, and their associations with the highly speciose and ecologically diverse cool-season grasses.

Results strongly suggest that at least some genes of ergot alkaloid biosynthesis in C. purpurea are clustered, opening the way for a detailed molecular genetic analysis of the pathway.

Investigation of the role of two NADPH oxidases in the necrotrophic phytopathogenic fungus, Botrytis cinerea, and the structure of the fungal Nox complex showed evidence that BcnoxR is involved in activation of both BCNox enzymes, providing evidence of pathogenicity of both genes.
BcSAK1, a Stress-Activated Mitogen-Activated Protein Kinase, Is Involved in Vegetative Differentiation and Pathogenicity in Botrytis cinerea
Data indicate that in B. cinerea the stress-activated MAPK cascade is involved in essential differentiation programs, and mutants are significantly impaired in vegetative and pathogenic development.
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…
Two potential H(2)O(2)-generating systems were studied with respect to their impact on the interaction of B. cinerea and its host plant Phaseolus vulgaris, and it is shown that the Cu-Zn SOD-activity is an important single virulence factor in this interaction system.
BOTRYTIS SPP. AND DISEASES THEY CAUSE IN AGRICULTURAL SYSTEMS - AN INTRODUCTION
The increasing requirement for alternative approaches to reduce farmers' dependency on use of fungicides led to the evaluation and exploitation of potential biocontrol agents capable of substantial disease suppression in a commercial context, and within integrated crop management systems.

The recent identification of a cluster of genes involved in ergot alkaloid biosynthesis in C. purpurea and the availability of molecular genetic techniques allow the development of strategies for rational drug design of ergoline-related drugs by enzyme engineering and by biocombinatorial approaches.
