Estimating the frequency of virulence against an Stb gene in Zymoseptoria tritici populations by bulk phenotyping on checkerboard microcanopies of wheat NILs

F. Suffert, S. Le Prieur, S. Gelisse, E. Dzialo, C. Saintenac, T. C. Marcel

The paper develops a bulk phenotyping method to estimate virulence frequency in Zymoseptoria tritici populations using checkerboard microcanopies of wheat NILs and validates it with synthetic populations.

Can higher aggressiveness effectively compensate for a virulence deficiency in plant pathogen? A case study of Puccinia triticina's fitness evolution in a diversified varietal landscape

C. Fontyn, K. J. Meyer, A.-L. Boixel, C. Picard, A. Destanque, T. C. Marcel, F. Suffert, H. Goyeau

This study shows that higher aggressiveness can compensate for virulence deficiencies in Puccinia triticina, explaining its competitive advantage over a virulent pathotype in a wheat landscape.

A secreted protease-like protein in Zymoseptoria tritici is responsible for avirulence on Stb9 resistance gene in wheat

R. Amezrou, C. Audeon, J. Compain, S. Gelisse, A. Ducasse, C. Saintenac, N. Lapalu, C. Louet, S. Orford, D. Croll, J. Amselem, S. Fillinger, T. C. Marcel

The paper identifies AvrStb9, a secreted protease-like protein in Zymoseptoria tritici, as an avirulence factor that interacts with the wheat Stb9 resistance gene to trigger immune responses.

Evolution within a given virulence phenotype (pathotype) is driven by changes in aggressiveness: a case study of French wheat leaf rust populations

C. FONTYN, K. J. MEYER, A.-L. BOIXEL, G. DELESTRE, E. PIAGET, C. PICARD, F. SUFFERT, T. C. MARCEL, H. GOYEAU

The paper shows that changes in aggressiveness drive evolution within a virulence phenotype in French wheat leaf rust populations, with more recent genotypes being more aggressive than older ones.

Is virulence phenotype evolution driven exclusively by Lr gene deployment in French Puccinia triticina populations?

C. Fontyn, A.-C. Zippert, G. Delestre, T. C. Marcel, F. Suffert, H. Goyeau

The paper examines the evolution of virulence in Puccinia triticina populations in France, finding that Lr gene deployment drives virulence changes, but aggressiveness and other factors also play a role.

The quasi-universality of nestedness in the structure of quantitative plant-parasite interactions

B. Moury, J.-M. Audergon, S. Baudracco-Arnas, S. BEN KRIMA, F. Bertrand, N. Boissot, M. Buisson, V. Caffier, M. Cantet, S. Chaneac, C. Constant, F. Delmotte, C. Dogimont, J. Doumayrou, F. Fabre, , Y. Ruellan

The paper analyzes nestedness and modularity in plant-parasite interaction matrices and finds high nestedness in most cases, with limited modularity and links to resistance traits.

Differential tolerance of Zymoseptoria tritici to altered optimal moisture conditions during the early stages of wheat infection

A.-L. Boixel, S. Gelisse, T. C. Marcel, F. Suffert

This study examines how Zymoseptoria tritici responds to altered moisture conditions during early wheat infection, finding variation in tolerance among strains and populations.
