Burning the Forest, Not Just the Trees

Fires increase the number of fungi when aspen groves regenerate.

The Science

Wildfires don’t only damage the visible parts of plants. They also affect the plant microbiome—the microorganisms living in association with plant tissues. Understanding these effects helps scientists mitigate the effects of wildfires by helping them understand how vegetation regenerates and how the plant microbiome helps the ecosystem recover. For this research, scientists examined microbial DNA samples from tissues of young quaking aspen saplings after a prescribed burn. Aspen relies largely on fire to regenerate. Before this study, scientists expected that fire would have fewer effects on the microbial communities within aspen tissues than on the microbes outside the plant. This work demonstrates that fire affects the entire plant microbiome. This means the effects of fire extend beyond the rhizosphere (the region of soil near the plant roots) and the bulk soil beyond the roots.

The Impact

Wildfires are increasing in frequency and severity. This trend can hurt forest ecosystem stability. Scientists know that the plant microbiome has a significant influence on plants’ fitness and their ability to survive stressful events such as fire. Researchers therefore need to understand the response of the plant microbiome to fire and how it helps plants recover. This study examined the leaf, stem, root, rhizome, and rhizosphere microbiomes of aspen saplings and associated bulk soil after a high-intensity prescribed fire. The results demonstrate that fire has a significant impact on the whole plant microbiome. This plant microbiome differs from the microbial habitats in the plant alone and in the soil alone. The results expand scientists’ knowledge of microbiome communities and microbiology as a whole.

Summary

This research sought to understand how fire influences the assembly and composition of the microbiome in regenerating Populus tremuloides (aspen) stands. The study found that fire severity is associated with reduced diversity of bacteria and a greatly increased dominance of fungal pathogens in the leaves of regenerating aspen. This study is the first to characterize the fire response of the whole plant microbiome, furthering knowledge of how microbial communities are assembled and are impacted by disturbance such as fire. The findings extend previous studies by revealing how the microbiomes associated with different plant tissues change in response to fire. Source tracking showed the vertical inheritance of the sapling microbiome from the parent tree. The results demonstrate the impact of fire disturbance on plant microbiome assembly and composition and suggest that additional research would facilitate enhanced plant health and ecosystem recovery after a fire.

Molybdenum Limits Microbes’ Ability to Remove Harmful Nitrate from Soil
Department of Energy, Office of Science

The Oak Ridge Reservation is contaminated with acidic, high-nitrate-and high-metal substances. Microbes in this environment can use molybdenum to remove nitrate, but the low concentration of molybdenum at Oak Ridge limits how much nitrate the microbes can remove. Two studies examine why molybdenum is limited and the mechanisms some microbes use to survive these conditions.

Lawrence Berkeley National Laboratory

Berkeley Lab scientists have made significant progress in developing battery cathodes using a new class of materials that provide batteries with the same if not higher energy density than conventional lithium-ion batteries but can be made of inexpensive and abundant metals. Known as DRX, which stands for disordered rocksalts with excess lithium, this novel family of materials was invented less than 10 years ago and allows cathodes to be made without nickel or cobalt.

Leaf-cutter ants tend fungal gardens that convert lipids in leaves into lipids the ants can use for energy, building cells, and communication between organisms. New research has found that different regions of the ants’ fungal gardens were enriched with different lipids. This helps scientists understand communications between organisms in different kingdoms of life.
