Growth variation of an ambrosia fungus on different tree species indicates host specialization

mycolabadmin

This research demonstrates that ambrosia fungi, which are cultivated by beetles as food sources, grow better on certain types of trees. The fungus studied, Dryadomyces montetyi, grows faster and denser on hardwood trees like oak and beech compared to conifer trees like fir and Douglas-fir. This suggests that the fungal symbiont has evolved preferences for the same tree types that its beetle partner prefers, indicating a specialized relationship shaped by millions of years of evolution.

Various types of mycorrhizal fungi sequences detected in single intracellular vesicles

Researchers discovered that single fatty droplet-like structures inside plant roots can contain genetic material from multiple types of fungi, both Glomeromycotina and Mucoromycotina. They developed new molecular tools to detect and identify these fungi without bias. This finding suggests fungi may live together more intimately than previously thought, which could help us better understand how plants get nutrients from fungal partners in soil.

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

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.

Eight Fungal Species Associated with Ambrosia Beetles in Korea

This research identifies eight types of fungi that live in partnership with ambrosia beetles in Korea. These fungi are food sources for beetle larvae and adults. The study found that some fungi have specific relationships with particular beetle species, while others can associate with multiple beetle types. This work helps scientists understand how beetles spread fungi and potentially cause tree diseases like oak wilt.
