We used the PCR to study the presence of two plant pathogens in archived wheat samples from a long-term experiment started in 1843. The data were used to construct a unique 160-yr time-series of the abundance of Phaeosphaeria nodorum and Mycosphaerella graminicola, two important pathogens of wheat. During the period since 1970, the relative abundance of DNA of these two pathogens in the samples...

Cercospora leaf spot of olives is a serious defoliating disease attributed to Pseudocercospora cladosporioides. Although the disease is well distributed throughout olive growing regions of the world, its epidemiology and population structure remains unknown. The aim of this study was to establish the genetic variability of Spanish isolates of P. cladosporioides using DNA sequence data from the ...

Twelve microsatellite markers were developed for population analyses of the fungal pathogen, Dothistroma septosporum. Intersimple sequence repeat polymerase chain reaction (ISSR-PCR) and an enrichment protocol (fast isolation by amplified fragment length polymorphism of sequences containing repeats [FIASCO]) were both used to identify 28 unique microsatellite regions in the genome. From 22 prim...

Two mating-type genes, designated MAT1-1-1 and MAT1-2-1, were cloned and sequenced from the presumed asexual ascomycete Cladosporium fulvum (syn. Passalora fulva). The encoded products are highly homologous to mating-type proteins from members of the Mycosphaerellaceae, such as Mycosphaerella graminicola and Cercospora beticola. In addition, the two MAT idiomorphs of C. fulvum showed regions of...

Host resistance and synthetic antimicrobials such as fungicides are two of the main approaches used to control plant diseases in conventional agriculture. Although pathogens often evolve to overcome host resistance and antimicrobials, the majority of reports have involved qualitative host - pathogen interactions or antimicrobials targeting a single pathogen protein or metabolic pathway. Studies...

Black Sigatoka Disease, also called Leaf Streak Disease (BLSD), is caused by the fungus Mycosphaerella fijiensis and arguably one of most important pathogens affecting banana plantain industries. Theoretical results on its dynamics are rare, even though theoretical descriptions epidemics plant diseases valuable steps toward their efficient management. In this paper, we propose a mathematical mo...
