Article Synopsis
  • * A study analyzed 381 isolates using a genetic typing method, revealing low genetic diversity and high clonal reproduction among populations, indicating potential movement between walnut trees and a latent pathogenic lifestyle.
  • * Genetic comparisons showed different patterns between French populations and those from California and Spain, hinting at limited pathogen transmission from overseas but possible links to French vineyards, offering insights into the spread and factors contributing to walnut dieback in France.

Mycotoxin contamination of food and feed is a major global concern. Chronic or acute dietary exposure to contaminated food and feed can negatively affect both human and animal health. Contamination occurs through plant infection by toxigenic fungi, primarily and spp.

Article Synopsis
  • * Researchers found that the ancestor of Colletotrichum diverged around the late Cretaceous period, coinciding with the evolution of flowering plants, and highlighted instances of these fungi moving from dicots to monocots.
  • * Comparative gene analysis revealed that while these fungi share core genes for degrading plant cell walls, they exhibit significant differences in how they regulate these genes depending on the types of plants they infect.

Reptilia exploit a large diversity of food resources from plant materials to living mobile prey. They are among the first tetrapods that needed to drink to maintain their water homeostasis. Here were compare the feeding and drinking mechanisms in Reptilia through an empirical approach based on the available data to open perspectives in our understanding of the evolution of the various mechanisms determined in these Tetrapoda for exploiting solid and liquid food resources.
