The role of arbuscular mycorrhizal symbiosis in improving plant water status under drought

M Abdalla, M Bitterlich, J Jansa… - Journal of …, 2023 - academic.oup.com
Arbuscular mycorrhizal fungi (AMF) have been presumed to ameliorate crop tolerance to
drought. Here, we review the role of AMF in maintaining water supply to plants from drying …

The emergent rhizosphere: imaging the development of the porous architecture at the root-soil interface

JR Helliwell, CJ Sturrock, S Mairhofer, J Craigon… - Scientific reports, 2017 - nature.com
The rhizosphere is the zone of soil influenced by a plant root and is critical for plant health
and nutrient acquisition. All below ground resources must pass through this dynamic zone …

Mucilage exudation facilitates root water uptake in dry soils

MA Ahmed, E Kroener, M Holz… - Functional Plant …, 2014 - CSIRO Publishing
As plant roots take up water and the soil dries, water depletion is expected to occur in the
rhizosphere. However, recent experiments showed that the rhizosphere was wetter than the …

Microbial distribution in soils: physics and scaling

IM Young, JW Crawford, N Nunan, W Otten… - Advances in agronomy, 2008 - Elsevier
In a handful of fertile soil there are billions of microorganisms and yet, even with a
conservative estimate, the surface area covered by these organisms is considerably less …

Resolving time-dependent evolution of pore-scale structure, permeability and reactivity using X-ray microtomography

C Noiriel - Reviews in Mineralogy and Geochemistry, 2015 - pubs.geoscienceworld.org
