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 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 …

We performed a meta-analysis to search for a relation between the trophic type and latent
period of fungal pathogens. The pathogen incubation period and the level of resistance of …

In order to elucidate the genetic control of resistance to Melampsora larici‐populina leaf rust
in hybrid poplars, a Populus deltoides× P. trichocarpa F1 progeny was analysed for …

Foliar endophytes of Populus do not induce the hypersensitive response associated with
major genes for resistance to Melampsora leaf rust. But they could contribute to the …

This chapter covers the following: variability in virulence and pathotypes within Melampsora
larici-populina on poplar; variability in the pathogenicity of M. larici-populina, M. allii …

The first part of the chapter reviews the genetic systems of Populus and Salix and how they
form the basis for the various domestication and conservation options available today. The …

La necesidad de incrementar la producción de energía de origen renovable en España,
pasa por considerar la producción de biomasa como una de las posibles alternativas. Entre …

Biotroph pathogens establish intimate interactions with their hosts that are conditioned by
the successful secretion of effectors in infected tissues and subsequent manipulation of host …

The expansion of poplar culture in the north-central and northeastern regions of North
America has been limited because many poplar clones are susceptible to the leaf spot and …
