Decursin, Identified via High-Throughput Chemical Screening, Enhances Plant Disease Resistance via Two Independent Mechanisms

mycolabadmin

Researchers identified a natural compound called decursin from angelica plants that helps plants fight off dangerous fungal infections in two ways: it strengthens the plant’s own immune system and directly kills the fungal pathogens. This dual-action approach makes decursin a promising natural alternative to synthetic fungicides for protecting crops like wheat and tomatoes from diseases. The compound shows particular promise because it comes from plants, breaks down easily in the environment, and is more effective than other natural antimicrobial compounds currently used in agriculture.

Integration of Physiological, Transcriptomic and Metabolomic Reveals Molecular Mechanism of Paraisaria dubia Response to Zn2+ Stress

mycolabadmin

This research shows that a fungus called Paraisaria dubia can effectively clean up zinc pollution by removing 60% of zinc from contaminated environments. The fungus uses multiple survival strategies when exposed to zinc stress, including producing more protective slime-like substances on its surface and generating spores that are more resistant to harmful conditions. By studying the fungus at the molecular level, scientists discovered which genes and chemical compounds activate these protective responses, paving the way for using fungi as natural cleaners for heavy metal-contaminated soil and water.

Transcriptome Analysis Reveals Mechanisms of Stripe Rust Response in Wheat Cultivar Anmai1350

mycolabadmin

Researchers studied how a wheat variety called Anmai1350 defends itself against a fungal disease called stripe rust caused by Puccinia striiformis. By analyzing gene activity at different time points after infection, they discovered that the wheat plant’s immune system activates multiple defense strategies, including producing toxic molecules called reactive oxygen species and defensive compounds called phytoalexins that prevent the fungus from spreading. This research helps scientists understand how to breed wheat varieties that can naturally resist this damaging disease and maintain crop yields.

Neuroprotective Effect of Mixed Mushroom Mycelia Extract on Neurotoxicity and Neuroinflammation via Regulation of ROS-Induced Oxidative Stress in PC12 and BV2 Cells

mycolabadmin

A mixture of three medicinal mushrooms (Phellinus linteus, Ganoderma lucidum, and Inonotus obliquus) was tested for its ability to protect nerve cells from damage. The extract successfully reduced cell death in laboratory models of neurodegeneration by reducing harmful molecules called reactive oxygen species and reducing inflammation. These results suggest the mushroom extract could potentially help prevent or slow neurological diseases like Alzheimer’s.

Modulating the gut microbiota is involved in the effect of low-molecular-weight Glycyrrhiza polysaccharide on immune function

mycolabadmin

Researchers studied a natural compound from licorice called Glycyrrhiza polysaccharide (GP) to see if it could help restore immune function in mice weakened by chemotherapy. GP treatment improved intestinal health, boosted immune cells, and changed the gut bacteria composition to favor beneficial strains. The study shows that GP works partly by modifying which bacteria live in the gut, which then support the immune system. This research suggests GP could be useful as a natural supplement for strengthening immunity and treating intestinal inflammation.

Insights into the evolution and mechanisms of response to heat stress by whole genome sequencing and comparative proteomics analysis of the domesticated edible mushroom Lepista sordida

mycolabadmin

Researchers sequenced the complete genome of Lepista sordida, a delicious edible mushroom valued for its health benefits, and studied how this mushroom responds to heat stress at the molecular level. Using advanced analysis techniques, they identified key proteins and signaling pathways that help the mushroom survive high temperatures. These findings can help farmers develop better-performing strains that are more resistant to heat, improving mushroom production.

Control effects and mechanisms of metabolites from Streptomyces ahygroscopicus var. gongzhulingensis strain 769 on sclerotinia rot in sunflowers

mycolabadmin

Scientists discovered that a beneficial soil bacterium called Streptomyces can effectively control sunflower rot disease caused by a harmful fungus. When applied to soil or roots, this bacterium reduced disease severity by over 50% and improved plant root health and seed quality. The treatment works by both directly killing the pathogenic fungus and strengthening the plant’s natural defense systems.

GlSlt2 positively regulates GlMyb-mediated cellulose utilization in Ganoderma lucidum

mycolabadmin

Scientists discovered how a medicinal mushroom called Ganoderma lucidum breaks down cellulose from plant waste. The study found that a protein called GlSlt2 activates another protein called GlMyb, which then turns on genes that produce cellulase enzymes. These enzymes break down cellulose into sugar that the fungus can use for growth. This discovery could help improve the conversion of agricultural waste into biofuels and other useful products.

The Effect of Natural-Based Formulation (NBF) on the Response of RAW264.7 Macrophages to LPS as an In Vitro Model of Inflammation

mycolabadmin

Researchers tested a natural mixture of five medicinal mushrooms combined with cannabidiol (CBD) on immune cells exposed to bacterial endotoxins. The formulation effectively reduced inflammatory response markers without harming the cells. These findings suggest the mixture could potentially be used to treat inflammatory conditions like asthma and arthritis, though more research is needed.

Halotolerant Endophytic Fungi: Diversity, Host Plants, and Mechanisms in Plant Salt–Alkali Stress Alleviation

mycolabadmin

Salty and alkaline soil is destroying farmland worldwide, but special fungi living inside plants can help crops survive these harsh conditions. These fungi work like a team with plants, producing protective substances and helping plants manage salt and reduce damage from stress. Scientists reviewed 150 studies and found these fungi boost crop yields by 15-40%, offering a natural way to farm on degraded land without more chemicals.
