Genome-wide identification of PSKR genes in wheat and differential expression under abiotic stress conditions

mycolabadmin

Scientists identified 149 genes related to phytosulfokine receptors (PSKR) in wheat that help plants respond to environmental stresses like drought, salt, cold, and heat. These genes are spread across wheat’s chromosomes and contain regulatory elements that control their expression in response to various stresses and plant hormones. The study provides important genetic resources for developing wheat varieties that are more resistant to environmental stress, which is crucial for maintaining crop productivity in changing climate conditions.

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

mycolabadmin

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.

Low Temperature Enhances N-Metabolism in Paxillus involutus Mycelia In Vitro: Evidence From an Untargeted Metabolomic Study

mycolabadmin

This study examined how a common forest fungus (Paxillus involutus) responds to cold temperatures by analyzing its chemical composition. When kept at cold temperatures like those found in spring and autumn forests, the fungus took up and used more nitrogen for making amino acids and other nitrogen compounds, even though it grew more slowly. This suggests that cold-adapted fungi have special mechanisms to acquire nutrients efficiently in cold conditions, which may be important for how they help trees survive in changing climates.

High temperature enhances the ability of Trichoderma asperellum to infect Pleurotus ostreatus mycelia

mycolabadmin

Researchers discovered that summer heat makes oyster mushroom crops more vulnerable to green mold disease caused by a fungus called Trichoderma asperellum. When exposed to high temperatures (36°C), the pathogenic fungus becomes more aggressive by producing more spores, germinating faster, and generating molecules like hydrogen peroxide that damage the mushroom mycelia. Meanwhile, the oyster mushroom itself becomes more susceptible to infection at these higher temperatures, explaining why green mold outbreaks are so common during hot summer months in mushroom farms.

Transcriptomic and metabolic profiling reveals adaptive mechanisms of Auricularia heimuer to temperature stress

mycolabadmin

Researchers studied how a popular edible mushroom called black wood ear (Auricularia heimuer) adapts to different temperatures. They found that the mushroom grows best at 35°C but struggles at very cold (15°C) or extremely hot (45°C) temperatures. By analyzing the genes and chemicals produced by the mushroom at different temperatures, scientists discovered that the mushroom uses different survival strategies depending on how hot or cold it is, which could help farmers grow better mushrooms.
