Asymmetric mitonuclear interactions trigger transgressive inheritance and mitochondria-dependent heterosis in hybrids of the model system Pleurotus ostreatus

mycolabadmin

This research examines how mushroom hybrids inherit different combinations of genes from their parents, specifically looking at genes in the nucleus versus the mitochondria (cellular energy factories). When mushrooms with mismatched nuclear and mitochondrial genes are crossed, some grow slowly and show stress, while others surprisingly grow very well. The study identifies which genes are activated under these conditions and how they affect mushroom production quality and yield.

Low temperature, mechanical wound, and exogenous salicylic acid (SA) can stimulate the SA signaling molecule as well as its downstream pathway and the formation of fruiting bodies in Flammulina filiformis

mycolabadmin

Researchers studied how cooling, physical damage, and a plant hormone called salicylic acid can trigger fruiting body formation in an edible mushroom called Flammulina filiformis. They discovered that these treatments activate specific genes in the mushroom that control fruit production. This research helps explain why mushroom farmers use these methods and could improve mushroom cultivation efficiency.

Impact of Phellinus gilvus mycelia on growth, immunity and fecal microbiota in weaned piglets

mycolabadmin

Researchers tested whether a medicinal mushroom called Phellinus gilvus could replace antibiotics in pig feed as a growth promoter. Over 28 days, piglets fed mushroom-supplemented diets grew as well as those given antibiotics while showing even better immune system activation. Unlike antibiotics that drastically changed the gut bacteria composition, the mushroom only slightly modified it while still reducing harmful E. coli bacteria. This suggests the mushroom could be a safer alternative to antibiotics in pig farming.

A New Exopolysaccharide from a Wood-Decaying Fungus Spongipellis borealis for a Wide Range of Biotechnological Applications

mycolabadmin

Researchers isolated and studied a new polysaccharide from the wood-decaying mushroom Spongipellis borealis. This polysaccharide is composed mainly of glucose, galactose, and mannose sugars and acts as a natural stabilizer for important enzymes used in biotechnology. When this polysaccharide is added to enzyme preparations, it significantly improves their stability and performance under various conditions, making it promising for industrial and medical applications.

A new type of calcium-rich biochars derived from spent mushroom substrates and their efficient adsorption properties for cationic dyes

mycolabadmin

Researchers developed a low-cost material called biochar from leftover mushroom growing substrates that can effectively remove harmful dyes from wastewater. By heating these spent mushroom substrates to high temperatures, they created a porous material rich in calcium that works as a powerful filter. This biochar can be used multiple times and doesn’t require expensive chemical treatments, making it practical for large-scale wastewater cleanup in textile and related industries.

Identification of matB used as an endogenous reference gene for the qualitative and real-time quantitative polymerase chain reaction detection of Lentinus edodes

mycolabadmin

This study identifies the matB gene as a reliable genetic marker for detecting shiitake mushrooms (Lentinus edodes) in food products. Researchers developed a simple DNA test that can identify L. edodes in processed foods where it might be fraudulently substituted for more expensive wild mushrooms. The test is highly sensitive, detecting DNA at extremely low concentrations, and works on both raw mushrooms and processed products. This method provides food manufacturers and regulators with an effective tool to prevent mushroom fraud and ensure food authenticity.

Construction of a heat-resistant strain of Lentinus edodes by fungal Hsp20 protein overexpression and genetic transformation

mycolabadmin

Scientists successfully created a heat-resistant version of shiitake mushrooms by adding extra copies of a heat-protection gene from button mushrooms. The modified mushrooms can survive higher temperatures and recover better after heat stress compared to regular shiitake strains. This genetic improvement could help shiitake farming expand to warmer regions and times of year, potentially increasing production worldwide.

Multi-Omics Analysis of Low-Temperature Fruiting Highlights the Promising Cultivation Application of the Nutrients Accumulation in Hypsizygus marmoreus

mycolabadmin

Scientists studied how beech mushrooms develop during a special low-temperature fruiting process that requires a long waiting period. They discovered that amino acids (particularly arginine) and citric acid accumulate during this process, and that adding these compounds externally can speed up mushroom production by 10 days and increase yield by 10-15%. This research could help mushroom farmers reduce costs and time in cultivation.

Efficient conversion of tea residue nutrients: Screening and proliferation of edible fungi

mycolabadmin

Tea leaves left over from making instant tea are usually thrown away, but researchers found that special edible mushrooms can break down these tea residues and convert them into nutritious mushroom protein. Monascus kaoliang B6 was the most effective, using powerful enzymes to decompose the tough plant fibers in tea residue and transform the nutrients into edible mushroom biomass. This discovery offers an environmentally friendly way to recycle tea industry waste into a useful food product without using harsh chemicals.

Fermentation With Pleurotus Ostreatus Enhances the Prebiotic Properties of Germinated Riceberry Rice

mycolabadmin

This research shows that black-purple Riceberry rice can be made healthier by sprouting it and then fermenting it with oyster mushroom mycelium. The resulting product contains beneficial compounds called GABA and β-glucan that help healthy gut bacteria grow while preventing harmful bacteria like E. coli. This improved rice product could be used in foods for elderly people to support digestive and overall health.
