High‐resolution synchrotron imaging shows that root hairs influence rhizosphere soil structure formation
In this paper, we provide direct evidence of the importance of root hairs on pore structure

High resolution synchrotron imaging of wheat root hairs growing in soil and image based modelling of phosphate uptake
Root hairs are known to be highly important for uptake of sparingly soluble nutrients,
particularly in nutrient deficient soils. Development of increasingly sophisticated mathematical …

Root hair formation in rice (Oryza sativa L.) differs between root types and is altered in artificial growth conditions
Root hairs are important sites for nutrient uptake, especially in P limiting conditions. Here
we provide first insights into root hair development for the diverse root types of rice grown …

[HTML][HTML] Challenges in imaging and predictive modeling of rhizosphere processes
Background Plant-soil interaction is central to human food production and ecosystem function.
Thus, it is essential to not only understand, but also to develop predictive mathematical …

Multimodal correlative imaging and modelling of phosphorus uptake from soil by hyphae of mycorrhizal fungi
S Keyes, A Van Veelen, D McKay Fletcher… - New …, 2022 - Wiley Online Library
Phosphorus (P) is essential for plant growth. Arbuscular mycorrhizal fungi (AMF) aid its uptake
by acquiring P from sources distant from roots in return for carbon. Little is known about …

Image-based modelling of nutrient movement in and around the rhizosphere
In this study, we developed a spatially explicit model for nutrient uptake by root hairs based
on X-ray computed tomography images of the rhizosphere soil structure. This work extends …

Soil carbon dioxide venting through rice roots
The growth of rice in submerged soils depends on its ability to form continuous gas channels—aerenchyma—through
which oxygen (O 2 ) diffuses from the shoots to aerate the roots. …
