Physiological response of chestnuts (Castanea mollissima Blume) infected by pathogenic fungi and their correlation with fruit decay

mycolabadmin

This study examined how three types of fungal infections cause chestnuts to rot and decay. Researchers found that fungi produce enzymes that break down cell walls and trigger the fruit’s defense mechanisms, leading to tissue damage. When multiple fungi infect together, the damage is worse than individual infections. The findings suggest that reducing mechanical damage, using cold storage, modified atmosphere, and antimicrobial treatments can effectively prevent chestnut rot during storage.

Infection of Norway spruce by Chrysomyxa rhododendri: ultrastructural insights into plant–pathogen interactions reveal differences between resistant and susceptible trees

mycolabadmin

Researchers studied how a rust fungus infects Norway spruce trees at the microscopic level, comparing healthy, resistant trees with ones that get severely infected. In resistant trees, the plant quickly builds protective barriers and accumulates compounds called tannins that slow down the fungus. Understanding these natural defenses could help foresters choose and grow spruce trees that better resist this devastating disease in high-altitude forests.

Intracellular accommodation of bacteria, fungi, and oomycetes by plants analyzed using transmission electron microscopy

mycolabadmin

Scientists used high-powered electron microscopes to examine how plants host different microorganisms inside their cells. They found that whether the microorganism is a helpful nitrogen-fixing bacterium, a nutrient-exchanging fungus, or a disease-causing oomycete, plants always separate it from the rest of the cell with a special membrane. This study reveals fundamental similarities in how plants accommodate different types of microorganisms, despite the very different outcomes for the plant.
