Editorial: Unraveling pathogen-plant-microbiome interactions in horticultural crops through omics approaches

mycolabadmin

This editorial presents a collection of research on how diseases affect valuable crops like tomatoes, tea, and potatoes. Scientists used advanced genetic and molecular techniques to understand how pathogens infect plants and how the beneficial microbes around plant roots can help fight disease. The studies suggest that managing crop diseases sustainably requires understanding the complex interactions between pathogens, plants, and their microbial communities.

Microbial communities associated with the black morel Morchella sextelata cultivated in greenhouses

mycolabadmin

This study examined the tiny organisms living on and around cultivated black morel mushrooms grown in greenhouses in China. Researchers found that four main types of bacteria consistently live on morel fruiting bodies: Pedobacter, Pseudomonas, Stenotrophomonas, and Flavobacterium. The bacteria and fungi in the soil surrounding morels appear to be important for the mushrooms’ growth and development, with different microbial communities found on different parts of the mushroom.

Spent casing, Sphagnum moss, grass fibers, and green compost as peat alternatives in casing soils for Agaricus bisporus cultivation

mycolabadmin

Button mushrooms are commonly grown on peat-based soil, but peat extraction damages important ecosystems. This study tested several alternative materials including spent mushroom substrate, moss, processed grass fibers, and compost as peat replacements. Researchers found that up to 75% of peat could be replaced with these alternatives while maintaining mushroom yield and preventing disease, offering promising sustainable options for commercial growers.

Starve or share? Phosphate availability shapes plant–microbe interactions

mycolabadmin

Plants need phosphate to survive, but it’s hard to find in soil. To solve this problem, plants partner with beneficial fungi and bacteria that help them absorb more phosphate. A master control system inside plants called PHR decides whether to be friendly with these helpful microbes or to defend against harmful ones, depending on how much phosphate is available. This clever system helps plants thrive even when nutrients are scarce.

Insights into microbiome-triterpenoid correlation in Poria cocos via comparative analysis of sclerotial and soil microenvironments

mycolabadmin

This study explores how the medicinal mushroom Poria cocos creates its own special microbial environment inside its sclerotium (the part used in medicine). Researchers found that the mushroom selectively enriches certain bacteria and fungi while maintaining lower overall microbial diversity compared to surrounding soil. The study reveals that specific microbes like Burkholderia and Scytalidium are positively associated with the production of pachymic acid, the mushroom’s key medicinal compound with anti-tumor and anti-inflammatory properties.

Spent casing, Sphagnum moss, grass fibers, and green compost as peat alternatives in casing soils for Agaricus bisporus cultivation

mycolabadmin

Researchers tested alternative materials to replace peat in the soil layer used for growing button mushrooms. They found that moss and compost could replace up to 75% of peat without reducing mushroom yields, though grass-based materials were less effective. The study shows it is possible to move toward more sustainable mushroom farming while maintaining productivity and controlling plant diseases.
