Global status of wheat leaf rust caused by Puccinia triticina
Leaf rust caused by Puccinia triticina is the most common and widely distributed of the three wheat rusts. Losses from leaf rust are usually less damaging than those from stem rust and stripe rust,… Expand
Aggressiveness and its role in the adaptation of plant pathogens
Aggressiveness, the quantitative component of pathogenicity, and its role in the adaptation of plant pathogens are still insufficiently investigated. Using mainly examples of biotrophic and… Expand
Cereal variety and species mixtures in practice, with emphasis on disease resistance
Les varietes en melanges, de par leur diversite genetique, limitent le developpement des epidemies et des ravageurs. Cette diversite peut etre organisee selon notre connaissance des interactions hote… Expand
Aggressiveness components and adaptation to a host cultivar in wheat leaf rust.
Experimental evidence on the capacity of pathogen populations to quantitatively adapt to their hosts and on the life traits that are involved is lacking at this time. In this article, we identified a… Expand
Distribution of pathotypes with regard to host cultivars in French wheat leaf rust populations.
ABSTRACT Isolates of wheat leaf rust collected from durum and bread wheat cultivars in France during 1999-2002 were analyzed for virulence on 18 Thatcher lines with single genes for leaf rust… Expand

Clonal reproduction in Puccinia triticina, the cause of wheat leaf rust, has long been hypothesized but has never been demonstrated. Using a population genetics approach and microsatellite markers,… Expand
Comparative effect of temperature and interrupted wet periods on germination, penetration, and infection of Puccinia recondita f. sp. tritici and P. striiformis on wheat seedlings
Under optimal temperature and nonlimiting wetness duration, the infection efficiency (defined as the proportion of inoculated urediniospores causing lesions on wheat seedling leaves) was 12 times… Expand
European virulence survey for leaf rust in wheat
With standardised near isogenic line (NIL) differentials co-operators were able to present the first comprehensive virulence survey of the European wheat leaf rust population (1996-1999). The work… Expand
Low diversity and fast evolution in the population of Puccinia triticina causing durum wheat leaf rust in France from 1999 to 2009, as revealed by an adapted differential set
No internationally agreed differential set is available for characterization of virulences in populations of Puccinia triticina causing wheat leaf rust on durum wheat. In a first step, 73 potentially… Expand
Resistance of European winter wheat germplasm to leaf rust
Pendant au moins deux ans, 72 cultivars et lignees de selection avancees de ble ont ete testees aux champs dans dix pays europeens pour evaluer la resistance a la rouille des feuilles. De plus, la… Expand
