Pest Management Science, EarlyView.This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

The Phytophthora infestans avirulence gene PiaAvr4 and its potato counterpart R4 [PDF]
, 2009 The potato late blight disease that is caused by the oomycete pathogen Phytophthora infestans is a major threat for potato crops worldwide. In recent years research on oomycete plant pathogens was boosted by the availability of novel genomic tools and ...

Aberrant mRNA Processing of the Maize Rp1-D Rust Resistance Gene in Wheat and Barley
Molecular Plant-Microbe Interactions, 2004 The maize Rp1-D gene confers race-specific resistance against Puccinia sorghi (common leaf rust) isolates containing a corresponding avrRp1-D avirulence gene.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders
Insect Science, EarlyView.Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Molecular Microbiology, EarlyView.Abbreviated Summary The role of the major fungal cell wall polymer α‐1,3‐glucan in plant infection is poorly understood. Deletion mutants of the maize anthracnose fungus Colletotrichum graminicola lacking all three α‐1,3‐glucan synthase genes differentiated severely distorted biotrophic hyphae in planta, and virulence was strongly reduced.

The Cladosporium fulvum Avr2 protein behaves both as a virulence and an avirulence factor [PDF]
, 2010 Plants are not able to move or escape and have to confront environmental challenges like nutrient and water deprivation, low and high temperatures, and biotic stress imposed by pathogens like viruses, bacteria, fungi, nematodes and insects that all ...

, 2010 International audienceIn gene-for-gene systems, resistance of a plant to a pathogen is due to the ‘recognition’ by plant surveillance system (i.e. plant resistance gene product) of a pathogen avirulence determinant encoded by an avirulence gene to ...

Balancing Selection at the Tomato RCR3 Guardee Gene Family Maintains Variation in Strength of Pathogen Defense [PDF]
, 2012 Coevolution between hosts and pathogens is thought to occur between interacting molecules of both species. This results in the maintenance of genetic diversity at pathogen antigens (or so-called effectors) and host resistance genes such as the major ...

Molecular Plant-Microbe Interactions, 2006 The HopPtoF locus in Pseudomonas syringae pv. tomato DC3000 harbors two genes, ShcF and HopF2 (previously named ShcFPto and HopFPto), that encode a type III chaperone and a cognate effector protein, respectively.
