Diversity and Ecology of Fungi from Underexplored and Extreme Environments

mycolabadmin

This editorial discusses a special collection of studies exploring fungi that thrive in extreme and challenging environments around the world, from frozen Arctic lakes to salty lagoons and polluted soils. These fungi have evolved remarkable abilities to survive harsh conditions and can even help clean up contaminated environments or support plant growth in degraded soils. Researchers are discovering previously unknown fungal species and understanding how these organisms function in ecosystems, with potential applications for cleaning pollution, improving agriculture, and biotechnology.

The Biocontrol and Growth-Promoting Potential of Penicillium spp. and Trichoderma spp. in Sustainable Agriculture

mycolabadmin

This review explores how two common fungi, Penicillium and Trichoderma, can help crops grow better and resist diseases naturally. These beneficial fungi live in plant roots and soil, providing nutrients, protecting against harmful pathogens, and helping plants cope with environmental stress. They offer an environmentally friendly alternative to chemical pesticides and fertilizers, making them valuable for sustainable agriculture.

The Transcription Factor SsSR Mediates Ergosterol Biosynthesis and Virulence in Sclerotinia sclerotiorum

mycolabadmin

Scientists discovered that a specific protein called SsSR acts as a master switch controlling how dangerous a fungus called Sclerotinia sclerotiorum becomes when attacking plants. Unlike other protein switches that make the fungus grow faster, this one specifically controls the fungus’s ability to cause infection by managing the production of ergosterol, a critical component of the fungus’s cell membranes. This discovery could lead to new ways to protect crops like oilseed rape from this devastating disease.

The Kelch Repeat Protein VdKeR1 Is Essential for Development, Ergosterol Metabolism, and Virulence in Verticillium dahliae

mycolabadmin

Verticillium dahliae is a serious fungal disease that kills many important crops like cotton and tomato by clogging their water-conducting vessels. Scientists discovered a protein called VdKeR1 that helps this fungus grow and cause disease by controlling how it makes ergosterol, a crucial component of fungal cell membranes. When researchers removed this protein, the fungus grew poorly, couldn’t form survival structures, and was much less dangerous to plants.

Transcriptome Analysis Reveals Critical Genes Involved in the Response of Stropharia rugosoannulata to High Temperature and Drought Stress

mycolabadmin

This study examined how a type of edible mushroom called Stropharia rugosoannulata responds to high heat and dry conditions by analyzing which genes become active. Researchers found that under stress, the mushroom activates specific genes that help it survive, particularly through a cellular communication pathway called MAPK. They identified 15 key genes that could be useful for breeding mushroom varieties that better withstand harsh growing conditions, which could improve mushroom farming efficiency.
