Function of Transcription Factors PoMYB12, PoMYB15, and PoMYB20 in Heat Stress and Growth of Pleurotus ostreatus

mycolabadmin

This research explores how specific genes in oyster mushrooms help them survive and grow better when exposed to heat stress. Scientists created mutant mushroom strains by either increasing or decreasing expression of three genes called PoMYB12, PoMYB15, and PoMYB20. They found that boosting PoMYB12 and PoMYB20 made mushrooms more heat-resistant and grow faster, while reducing PoMYB15 had similar beneficial effects. These discoveries could help farmers grow better oyster mushrooms during hot summer months when heat damage is a major problem.

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

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.

Comparative Transcriptome Profiles of the Response of Mycelia of the Genus Morchella to Temperature Stress: An Examination of Potential Resistance Mechanisms

Scientists studied how morel mushrooms respond to different temperatures to understand why cultivation can be unpredictable. By analyzing gene activity in mushroom mycelia (the underground filaments) at temperatures from 5°C to 30°C, they found that 15-20°C was ideal for growth. At higher temperatures, the mushrooms showed signs of stress similar to heat damage in other organisms, turning brownish and activating protective genes. This research helps mushroom farmers optimize growing conditions for better yields.

Analysis of the chitin synthase gene family in Ganoderma lucidum: its structure, phylogeny, and expression patterns

mycolabadmin

Scientists studied eight chitin synthase genes in Ganoderma lucidum (reishi mushroom), which are important for building the fungal cell wall and controlling growth. They found that different genes are active at different stages of mushroom development and that six of these genes become more active when exposed to high temperatures, suggesting they help the mushroom survive heat stress. This research helps us understand how mushrooms grow and develop, which could lead to better cultivation methods.

Transcriptional response of mushrooms to artificial sun exposure

As climate change causes more trees to die and forest canopies to open up, mushrooms on the forest floor are exposed to more intense sun and heat. Researchers exposed Shiitake mushrooms to artificial sunlight and found that the mushrooms activate protective molecular mechanisms, particularly heat-shock proteins, to cope with the stress. This suggests that mushrooms have built-in defenses against harsh sun exposure, though scientists are not yet sure if these defenses are strong enough to protect mushroom reproduction under real-world climate change conditions.

Thermotolerance and post-fire growth in Rhizina undulata is associated with the expansion of heat stress-related protein families

mycolabadmin

Scientists sequenced the genome of a fungus called Rhizina undulata that uniquely depends on fire to activate its growth and infect conifer trees. By comparing this fungus to related species, they discovered it has extra copies of genes that produce special proteins for handling heat stress and dealing with the chemical changes that occur after fires. This finding helps explain how the fungus survives extreme heat and thrives in fire-damaged forests, which is important knowledge for forest management.

Thermotolerance and post-fire growth in Rhizina undulata is associated with the expansion of heat stress-related protein families

mycolabadmin

Rhizina undulata is a fungus that infects conifer trees and uniquely relies on the heat from forest fires to wake up and start growing. Scientists sequenced the fungus’s DNA and discovered it has extra copies of genes that help it survive extreme heat, deal with harmful molecules created by heat stress, and digest burned plant material. These genetic adaptations explain how this fungus has evolved to take advantage of fire events for its survival and spread.
