Aphids Influence Soil Fungal Communities in Conventional Agricultural Systems

open access: yesFrontiers in Plant Science, 2019
Arbuscular mycorrhizal fungi (AMF) form symbioses with the roots of most plant species, including cereals. AMF can increase the uptake of nutrients including nitrogen (N) and phosphorus (P), and of silicon (Si) as well as increase host resistance to ...
