This review briefly addresses what has been learned about resistance durability in recent
years, as well as the questions that still remain. Molecular analyses of major gene …

This paper reviews current knowledge about genes for resistance to Septoria tritici blotch
(STB) of wheat, caused by Zymoseptoria tritici (formerly Mycosphaerella graminicola). These …

▪ Abstract Plant pathogens cause mortality and reduce fecundity of individual plants, drive
host population dynamics, and affect the structure and composition of natural plant …

In host-parasite coevolutionary arms races, parasites probably have an evolutionary
advantage. Parasite populations should be locally adapted, having higher mean fitness on …

Aggressiveness, the quantitative component of pathogenicity, and its role in the adaptation
of plant pathogens are still insufficiently investigated. Using mainly examples of biotrophic …

The study of parasite local adaptation, whereby parasites perform better on sympatric hosts
than on allopatric hosts and/or better on their own host population than do other parasites, is …

The term virulence has a conflicting history among plant pathologists. Here we define
virulence as the degree of damage caused to a host by parasite infection, assumed to be …

Zymoseptoria tritici (previously Mycosphaerella graminicola) causes Septoria tritici blotch
(STB) on wheat. The population biology of Z. tritici has been exceptionally well characterized …

The first section presents the quantitative traits of pathogenicity that are most commonly
measured by plant pathologists, how the expression of those traits is influenced by …

Three cultivars of winter bread wheat (Gene, Madsen and Stephens) were each inoculated
as seedlings in the greenhouse with seven or eight individual isolates of Mycosphaerella …
