Integrated multi-omics identifies plant hormone signal transduction and phenylpropanoid biosynthesis as key pathways in kiwifruit (Actinidia chinensis var. deliciosa) resistance to Botryosphaeria Dothidea infection

mycolabadmin

Kiwifruit can be infected by a fungus called Botryosphaeria dothidea, which causes soft rot and makes the fruit inedible. Researchers used advanced techniques to study what happens inside the fruit when infected, finding that certain plant hormones and chemical pathways become active to fight the infection. They identified two key genes that appear to control how the fruit responds to the fungus, which could help develop better ways to prevent this costly disease.

2-Nonanol produced by Bacillus velezensis EM-1: a new biocontrol agent against tobacco brown spot

mycolabadmin

Researchers discovered that a beneficial bacterium called Bacillus velezensis produces a natural compound called 2-nonanol that effectively kills the fungus causing brown spots on tobacco leaves. This compound works by disrupting the fungus’s ability to obtain energy and handle stress. Testing on tobacco leaves showed that 2-nonanol could significantly reduce disease development. This discovery offers a promising environmentally-friendly alternative to chemical fungicides for protecting tobacco crops.

Reprogramming astrocytic NDRG2/NF-κB/C3 signaling restores the diabetes-associated cognitive dysfunction

mycolabadmin

This study found that regular exercise helps protect the brain of diabetic people from cognitive decline by boosting a protein called NDRG2 in astrocytes (brain support cells). The research shows that NDRG2 works by blocking harmful immune responses that damage synapses (connections between brain cells). In diabetic mice, exercise improved memory and learning ability while increasing NDRG2 levels, while blocking this protein reversed these benefits.

Cellular anatomy of arbuscular mycorrhizal fungi

mycolabadmin

This comprehensive review explains the unique cellular structure of arbuscular mycorrhizal fungi, which form vast underground networks connecting plants to soil nutrients. These fungi are remarkable because their hyphae lack internal walls, allowing nutrients and organelles to flow freely throughout their continuous cytoplasm. By synthesizing current knowledge about how these fungi are organized and function at the cellular level, the authors highlight how this organization enables the complex nutrient exchange that supports plant growth and ecosystem health worldwide.

Mechanism Analysis of Amphotericin B Controlling Postharvest Gray Mold in Table Grapes

mycolabadmin

Researchers discovered that amphotericin B, a natural compound produced by soil bacteria, effectively prevents gray mold disease on table grapes. The compound works by directly damaging the fungus’s cell membranes and also boosts the grape’s own defense mechanisms. This natural solution could replace harmful synthetic fungicides while extending the shelf life of grapes during storage and transport.

Unveiling molecular mechanisms of strobilurin resistance in the cacao pathogen Moniliophthora perniciosa

mycolabadmin

This research reveals how a fungus that causes disease in cacao plants survives treatment with strobilurin fungicides, which are commonly used in agriculture. Scientists discovered that the fungus adapts by reorganizing its metabolism to compensate for the drug’s effects, activating detoxification systems, and in some cases, developing genetic mutations that enhance resistance. Understanding these survival mechanisms could help develop better strategies to control this economically important crop disease.

Influence of Pleurotus sapidus fruiting bodies on the performance, cecal microbiome, and gene expression in the liver and breast muscle of broilers

mycolabadmin

Researchers tested whether edible mushroom fruiting bodies could be used as animal feed for chickens. They found that chickens fed diets containing oyster mushroom (Pleurotus sapidus) had reduced growth and lower nutrient absorption compared to control chickens. While mushroom-based feed appeared to increase beneficial gut bacteria diversity, it ultimately impaired overall chicken performance, suggesting mushroom fruiting bodies are not suitable as a primary feed component for commercial poultry production.

Arsenic Stress Resistance in the Endophytic Fungus Cladosporium cladosporioides: Physiological and Transcriptomic Insights into Heavy Metal Detoxification

mycolabadmin

Researchers discovered a special fungus called Cladosporium cladosporioides living inside the roots of Gentiana yunnanensis, a traditional Chinese medicinal herb. This fungus is remarkably good at tolerating and neutralizing arsenic, a toxic heavy metal found in contaminated soils. The fungus uses multiple strategies to protect itself from arsenic damage, including moving the arsenic to its cell walls, converting it into less toxic forms, and activating protective defense systems.

Antifungal Activity of Genistein Against Phytopathogenic Fungi Valsa mali Through ROS-Mediated Lipid Peroxidation

mycolabadmin

Scientists discovered that genistein, a natural compound found in soybeans and other legumes, can effectively kill the fungus that causes apple tree canker disease. The compound works by creating harmful reactive oxygen species that damage the fungus’s cell membranes and disrupt its normal cellular functions. This research suggests genistein could be developed as a safe, natural alternative to chemical fungicides for protecting apple crops.

A broad-spectrum anti-fungal effector dictates bacterial-fungal interkingdom interactions

mycolabadmin

Scientists discovered that a common soil bacterium called Acidovorax citrulli has a sophisticated weapon to fight dangerous fungi. This bacterium uses a needle-like structure to inject a toxic protein called TseN directly into fungal cells, where it damages the fungal DNA and causes death. This new discovery is particularly exciting because it works against drug-resistant fungi like Candida auris that are increasingly hard to treat. Tests in mice confirmed that this bacterial attack significantly reduces fungal infections on skin.
