Endophytic Beauveria spp. Enhance Tomato Growth and Resistance to Botrytis cinerea via Transcriptomic Regulation

mycolabadmin

Researchers tested five types of beneficial fungi from the Beauveria genus to see if they could help tomato plants grow better and resist gray mold disease. They found that all five species could live inside tomato plants and help them grow taller. Most importantly, the fungus Beauveria brongniartii completely protected plants from gray mold infection. By examining which genes were activated in the plants, scientists discovered that these fungi boost the plant’s natural defense systems while also improving photosynthesis.

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.

Mycorrhizae and grapevines: the known unknowns of their interaction for wine growers’ challenges

mycolabadmin

Arbuscular mycorrhizal fungi (AMF) form beneficial partnerships with grapevine roots, improving plant health and wine quality. These fungi help grapevines absorb water and nutrients more efficiently, making them more resistant to drought and diseases. The effectiveness of this partnership depends on which specific fungi are present, the type of grapevine rootstock used, and how vineyard soil is managed. As climate change creates new challenges for wine growers, using AMF as natural biostimulants could help grapevines better tolerate heat, drought, and other stresses.

Recent Knowledge in the Application of Saccharomyces cerevisiae in Aquaculture: A Bibliometric and Narrative Review

mycolabadmin

This comprehensive review examines how baker’s yeast (Saccharomyces cerevisiae) is being used as a probiotic supplement in fish farming and aquaculture. The research shows that adding this yeast to fish feed improves growth rates, helps fish fight off diseases, and creates healthier gut bacteria in aquatic animals. Scientists worldwide are increasingly studying this natural alternative to antibiotics, with studies demonstrating benefits across various fish species including tilapia, trout, and catfish, making it an important tool for sustainable and healthier aquaculture practices.

Controlled inoculation provides insight into western redcedar resistance to multiple root- and butt-rot pathogens

mycolabadmin

Western redcedar is an economically important tree species suffering from fungal diseases that cause wood decay and significant financial losses. Researchers developed controlled methods to test how resistant young redcedar trees are to eight different decay fungi, finding that some fungi are much more damaging than others. Importantly, they discovered that some infections remain hidden without visible symptoms but still harm tree growth, and these hidden infections can be detected using advanced DNA-based methods. This research will help forest managers and breeders develop redcedar varieties with better disease resistance.
