High‐resolution synchrotron imaging shows that root hairs influence rhizosphere soil structure formation

N Koebernick, KR Daly, SD Keyes, TS George… - New …, 2017 - Wiley Online Library
In this paper, we provide direct evidence of the importance of root hairs on pore structure
development at the root–soil interface during the early stage of crop establishment. This was …

High resolution synchrotron imaging of wheat root hairs growing in soil and image based modelling of phosphate uptake

SD Keyes, KR Daly, NJ Gostling, DL Jones… - New …, 2013 - Wiley Online Library
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

J Nestler, SD Keyes, M Wissuwa - Journal of Experimental …, 2016 - academic.oup.com
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

T Roose, SD Keyes, KR Daly, A Carminati, W Otten… - Plant and soil, 2016 - Springer
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 …

Imaging the interaction of roots and phosphate fertiliser granules using 4D X-ray tomography

S Ahmed, TN Klassen, S Keyes, M Daly, DL Jones… - Plant and Soil, 2016 - Springer
Aims Plant root system architecture adapts to the prevailing soil environment and the distribution
of nutrients. Many species respond to localised regions of high nutrient supply, found in …

[HTML][HTML] Three dimensional imaging of paraffin embedded human lung tissue samples by micro-computed tomography

AE Scott, DM Vasilescu, KAD Seal, SD Keyes… - PloS one, 2015 - journals.plos.org
Background Understanding the three-dimensional (3-D) micro-architecture of lung tissue can
provide insights into the pathology of lung disease. Micro computed tomography (µCT) has …

Imaging microstructure of the barley rhizosphere: particle packing and root hair influences

N Koebernick, KR Daly, SD Keyes… - New …, 2019 - Wiley Online Library
Soil adjacent to roots has distinct structural and physical properties from bulk soil, affecting
water and solute acquisition by plants. Detailed knowledge on how root activity and traits …

Image-based modelling of nutrient movement in and around the rhizosphere

KR Daly, SD Keyes, S Masum… - Journal of experimental …, 2016 - academic.oup.com
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

…, A Boghi, MC Affholder, SD Keyes… - Plant, cell & …, 2019 - Wiley Online Library
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. …
