Innovative fungal bioagents: producing siderophores, IAA, and HCN to support plants under salinity stress and combat microbial plant pathogens

mycolabadmin

Scientists discovered two beneficial fungi that help wheat plants survive in salty soil and resist diseases. These fungi work by producing growth-promoting substances and natural compounds that fight harmful plant pathogens. When used to treat wheat seeds, these fungi significantly improved plant growth even under high salt stress conditions, offering a natural alternative to chemical fertilizers and pesticides for farming in salt-affected areas.

Actinorhizal plants and Frankiaceae: The overlooked future of phytoremediation

mycolabadmin

Actinorhizal plants are special trees and shrubs that team up with beneficial bacteria called Frankiaceae to clean up polluted and degraded soils. This natural partnership helps these plants survive harsh conditions like salty or heavy metal-contaminated soil while also cleaning up the environment. The bacteria help the plants by providing essential nitrogen and improving their ability to tolerate pollution, making them an inexpensive and sustainable solution for restoring degraded farmland.

Can the DSE Fungus Exserohilum rostratum Mitigate the Effect of Salinity on the Grass Chloris gayana?

mycolabadmin

Researchers tested whether a fungus called Exserohilum rostratum could help Rhodes grass tolerate salty soils. While the fungus survived well in salty conditions and colonized plant roots, it only moderately improved plant growth under high salt levels. The fungus did help plants maintain better potassium and calcium balance compared to non-inoculated plants, but this wasn’t always enough to overcome severe salt stress.

Mycorrhizae and grapevines: the known unknowns of their interaction for wine growers’ challenges

mycolabadmin

Arbuscular mycorrhizal fungi (AMF) form beneficial partnerships with grapevine roots, improving plant health and wine quality. These fungi help grapevines absorb water and nutrients more efficiently, making them more resistant to drought and diseases. The effectiveness of this partnership depends on which specific fungi are present, the type of grapevine rootstock used, and how vineyard soil is managed. As climate change creates new challenges for wine growers, using AMF as natural biostimulants could help grapevines better tolerate heat, drought, and other stresses.
