Repeated measures of decaying wood reveal the success and influence of fungal wood endophytes

mycolabadmin

Scientists tracked how fungi and bacteria decompose fallen tree logs over five years in a Minnesota forest. They discovered that fungi living dormant inside healthy wood trees become the dominant decomposers when wood begins to decay, outcompeting fungi arriving from soil and air. Wet, ground-contact conditions and bark coverage changed which fungi dominated, but bacterial communities followed a different pattern, remaining diverse regardless of conditions.

Rhizosphere Bacterial Communities Alter in Process to Mycorrhizal Developments of a Mixotrophic Pyrola japonica

mycolabadmin

This study explores how bacteria living around plant roots change as the plant develops its relationship with fungi. Researchers found that when fungi fully colonized plant roots in Pyrola japonica, the bacterial community became less diverse but more stable. Even after fungi died off, the bacterial community remained, suggesting these bacteria play an important long-term role in helping the plant obtain nutrients and resist diseases.

Rhizosphere Bacterial Communities Alter in Process to Mycorrhizal Developments of a Mixotrophic Pyrola japonica

mycolabadmin

This study examined how bacteria living around plant roots change as fungi form partnerships with a plant called Pyrola japonica. Researchers identified three stages of fungal development and found that bacterial communities were most diverse when fungi had not yet colonized roots or when they were degenerating. The findings suggest that fungi help shape and maintain the bacterial communities around roots, creating a beneficial three-way partnership between plants, fungi, and bacteria.
