Modified source–sink dynamics govern resource exchange in ectomycorrhizal symbiosis

LM Bogar - New Phytologist, 2024 - Wiley Online Library
Ectomycorrhizal symbiosis between roots and fungi is founded on the movement of carbon
from plants to fungi, and of soil resources from fungi to plants. Framing this movement as a …

Decay by ectomycorrhizal fungi couples soil organic matter to nitrogen availability

WA Argiroff, DR Zak, PT Pellitier, RA Upchurch… - Ecology …, 2022 - Wiley Online Library
Interactions between soil nitrogen (N) availability, fungal community composition, and soil
organic matter (SOM) regulate soil carbon (C) dynamics in many forest ecosystems, but …

Ectomycorrhizal fungi are more sensitive to high soil nitrogen levels in forests exposed to nitrogen deposition

K Jörgensen, KE Clemmensen, H Wallander… - New …, 2024 - Wiley Online Library
Ectomycorrhizal fungi are essential for nitrogen (N) cycling in many temperate forests and
responsive to anthropogenic N addition, which generally decreases host carbon (C) …

Insect‐plant‐fungus interactions in mycorrhizal associations, with a focus on spittlebugs and ectomycorrhizal host plants

V Thompson - Ecological Entomology, 2022 - Wiley Online Library
Mycorrhizal plants mediate interactions between their root‐associated fungal symbionts and
insect herbivores. Arbuscular mycorrhizal (AM) associations tend to boost phloem sap …

Ectomycorrhizal access to organic nitrogen mediates CO2 fertilization response in a dominant temperate tree

PT Pellitier, I Ibáñez, DR Zak, WA Argiroff… - Nature …, 2021 - nature.com
Plant–mycorrhizal interactions mediate plant nitrogen (N) limitation and can inform model
projections of the duration and strength of the effect of increasing CO2 on plant growth. We …

Ectomycorrhizal fungal decay traits along a soil nitrogen gradient

PT Pellitier, DR Zak - New Phytologist, 2021 - Wiley Online Library
The extent to which ectomycorrhizal (ECM) fungi decay soil organic matter (SOM) has
implications for accurately predicting forest ecosystem response to climate change …

Mycorrhiza better predict soil fungal community composition and function than aboveground traits in temperate Forest ecosystems

AA Fitch, AK Lang, ED Whalen, EM Helmers… - Ecosystems, 2023 - Springer
Forests in the northeastern US are experiencing shifts in community composition due to the
northward migration of warm-adapted tree species and certain species' declines (for …

Mycorrhizal fungal and tree root functional traits: Strategies for integration and future directions

SAZ Schaffer‐Morrison, DR Zak - Ecosphere, 2023 - Wiley Online Library
Plant functional traits offer ecologists quantifiable characteristics that may be used to
determine the underlying mechanisms and drivers of processes at scales ranging from …

The complex circuitry of interactions determining coexistence among plants and mycorrhizal fungi

MA McPeek, C Hicks Pries - Ecology, 2024 - Wiley Online Library
We present a mechanistic model of coexistence among a mycorrhizal fungus and one or two
plant species that compete for a single nutrient. Plant–fungal coexistence is more likely if the …

Fungal community composition and genetic potential regulate fine root decay in northern temperate forests

WA Argiroff, DR Zak, RA Upchurch… - Molecular …, 2023 - Wiley Online Library
