Betulinic Acid Delays Turnip Mosaic Virus Infection by Activating the Phytosulfokine Signalling Pathway in Nicotiana benthamiana

mycolabadmin

Researchers discovered that betulinic acid, a natural compound found in birch and eucalyptus trees, can slow down turnip mosaic virus infection in plants. The compound works by activating a plant hormone called phytosulfokine through special receptors on plant cells, which strengthens the plant’s natural defence against the virus. This finding suggests betulinic acid could become an environmentally friendly alternative to chemical pesticides for protecting vegetable crops from viral diseases.

A putative ABC transporter gene, CcT1, is involved in beauvericin synthesis, conidiation, and oxidative stress resistance in Cordyceps chanhua

mycolabadmin

Cordyceps chanhua is a medicinal fungus used in traditional Chinese medicine that produces a compound called beauvericin, which has health benefits but can be toxic in high amounts. Researchers discovered a gene called CcT1 that controls how much beauvericin the fungus makes. By removing this gene, they could reduce beauvericin production by 64%, making the fungus safer to use as medicine while maintaining other beneficial properties.

Inhibitory and synergistic effects of volatile organic compounds from bat caves against Pseudogymnoascus destructans in vitro

mycolabadmin

Researchers discovered that two natural compounds found in bat cave environments—isovaleric acid and ethyl methyl carbonate—can effectively kill the fungus that causes white-nose syndrome in bats. When used together, these compounds work even better than alone, disrupting the fungus’s cell membranes, causing it to produce too many reactive molecules (free radicals), and triggering cell death. This discovery offers hope for developing new treatments to protect bat populations that have been devastated by this disease in North America.

NtCML19 Is Recruited by Tobacco to Interact With the Deacetylase Protein RsDN3377 of Rhizoctonia solani AG3-TB, Inhibiting Fungal Infection

mycolabadmin

Tobacco plants are under attack from a fungal disease caused by Rhizoctonia solani. Scientists discovered that this fungus produces a protein called RsDN3377 that helps it grow and infect plants. However, tobacco plants have evolved a defense protein called NtCML19 that recognizes RsDN3377 and triggers an immune response to fight off the infection. By engineering tobacco plants to produce more NtCML19, researchers showed they could make the plants more resistant to the disease, suggesting a potential new strategy for protecting crops.

Genetic regulation of l-tryptophan metabolism in Psilocybe mexicana supports psilocybin biosynthesis

mycolabadmin

Researchers studied how magic mushrooms (Psilocybe mexicana) regulate their chemistry to produce psilocybin, the psychoactive compound. They found that when mushrooms start fruiting, they turn on genes that make tryptophan (an amino acid building block) and turn off genes that break it down, directing all the tryptophan toward psilocybin production. This coordinated genetic control ensures the mushroom has enough of this key ingredient. This knowledge could help grow these mushrooms in labs for legitimate medical research into treating depression.

Single-cell transcriptome profiles of Drosophila fruitless-expressing neurons from both sexes

mycolabadmin

Scientists studied individual nerve cells in fruit flies that control mating behaviors, comparing males and females at a critical developmental stage. Using advanced sequencing technology, they identified 113 distinct types of nerve cells with shared genes but sex-specific differences in expression. The findings reveal how the same basic neural circuits can be fine-tuned differently in males and females to produce their distinct reproductive behaviors.

Trichoderma brevicompactum 6311: Prevention and Control of Phytophthora capsici and Its Growth-Promoting Effect

mycolabadmin

Researchers isolated a beneficial fungus called Trichoderma brevicompactum from pepper plant soil that can fight a serious disease affecting peppers worldwide. This fungus not only kills the disease-causing pathogen but also helps pepper plants grow better. The study shows this fungus works through multiple mechanisms including wrapping around harmful fungi and producing growth-promoting compounds. This offers farmers an environmentally friendly alternative to chemical pesticides for protecting their pepper crops.

In vitro and in vivo efficacy of the antimycobacterial molecule SQ109 against the human pathogenic fungus, Cryptococcus neoformans

mycolabadmin

Researchers discovered that SQ109, an antimycobacterial drug, can effectively kill Cryptococcus fungi that cause serious brain infections in people with weakened immune systems. Unlike current treatments, cryptococcal cells don’t easily develop resistance to SQ109, and it works even better when combined with fluconazole. In mouse studies, SQ109 successfully treated cryptococcal infections, suggesting it could be a valuable new treatment option for patients worldwide, especially in resource-limited regions.

A Zn2-Cys6 transcription factor, TgZct4, reprograms antioxidant activity in the fungus Trichoderma guizhouense to defend against oxidative stress

mycolabadmin

This research identifies a special protein called TgZct4 in a beneficial fungus called Trichoderma guizhouense that helps it survive harmful stress from hydrogen peroxide. When the fungus encounters oxidative stress, TgZct4 quickly activates and switches on genes that produce protective enzymes. This discovery helps scientists understand how this fungus can be such an effective biological pest control agent and could lead to improvements in using it as a natural alternative to chemical pesticides.

Neuronal TIMP2 regulates hippocampus-dependent plasticity and extracellular matrix complexity

mycolabadmin

Scientists discovered that a protein called TIMP2, which is naturally higher in young blood, plays a crucial role in maintaining brain memory and learning ability. Using laboratory mice, they found that TIMP2 helps keep the brain’s cellular environment flexible by controlling the buildup of structural proteins around nerve connections. Without adequate TIMP2, the brain develops more rigid connections that interfere with forming new memories and creating new brain cells, mimicking changes seen in aging and cognitive decline.
