International Symposium on Cereal Leaf Blights, 5-9 juin 2024 à Zürich (Suisse)

Several teams from BIOGER were represented at ISCLB2024 in Zurich, highlighting the diversity of work being conducted on wheat septoria within our unit. This participation has strengthened the international visibility of our research, which is now well-recognized.

Pangenome-wide association study of quantitative pathogenicity in Zymoseptoria tritici

The quantitative component of pathogenicity in Zymoseptoria tritici and its adaptation to its host has been deciphered through whole-genome sequencing of the fungus followed by a pangenome-wide association study. This study, led at BIOGER by Thierry Marcel, has recently been published in the journal Nature Communications.

When higher aggressiveness compensates for a lack of virulence

Using wheat leaf rust as a case study, an experimental study conducted at BIOGER showed that higher aggressiveness (a quantitative component of pathogenicity) can compensate for a lack of virulence, meaning the inability to infect wheat varieties carrying a widely deployed resistance gene. This finding suggests that even if a pathogen lacks the specific ability to overcome certain resistance mechanisms, its overall aggressiveness — such as its ability to infect more rapidly or spread extensively — can still lead to significant disease development.

Methodological advances in characterizing Zymoseptoria tritici populations

A study conducted at BIOGER showed that it is possible to estimate the frequency of virulent strains in a pathogen population through "bulk" phenotyping on micro-wheat plots arranged in a checkerboard pattern.

Springtails feeding on a wheat pathogen fungus: a possible bioregulation of inoculum sources?

A study conducted by Thomas Bourgeois, a PhD student at MNHN*, in collaboration with BIOGER, has shown that the springtail Heteromurus nitidus "grazes" the fruiting bodies of Zymoseptoria tritici (septoria) on infected wheat tissues, thereby reducing the amount of available inoculum.

Is thermal aptitude a pivotal driver in the establishment of recent Puccinia striiformis f. sp. tritici lineages in Europe?

Answers to this question have recently been provided by Kevin Meyer and epidemiologist colleagues at BIOGER as part of the European H2020 RustWatch project.
