Loss of ancestral function in duckweed roots is accompanied by progressive anatomical reduction and a re-distribution of nutrient transporters (2023)
Journal Article

Organ loss occurs frequently during plant and animal evolution. Sometimes, non-functional organs are retained through evolution. Vestigial organs are defined as genetically determined structures that have lost their ancestral (or salient) function. D...

X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil (2022)
Journal Article

The spatial arrangement of the root system, termed root system architecture, is important for resource acquisition as it directly affects the soil zone explored. Methods for phenotyping roots are mostly destructive, which prevents analysis of roots o... Read More about X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil.

Dual expression and anatomy lines allow simultaneous visualization of gene expression and anatomy (2021)
Journal Article

Studying the developmental genetics of plant organs, requires following gene expression in specific tissues. To facilitate this, we have developed the Dual Expression Anatomy Lines (DEAL), which incorporate a red plasma membrane marker alongside a fl...

Non-invasive hydrodynamic imaging in plant roots at cellular resolution (2021)
Journal Article

A key impediment to studying water-related mechanisms in plants is the inability to non-invasively image water fluxes in cells at high temporal and spatial resolution. Here, we report that Raman microspectroscopy, complemented by hydrodynamic modelli... Read More about Non-invasive hydrodynamic imaging in plant roots at cellular resolution.

Positioning the Root Elongation Zone Is Saltatory and Receives Input from the Shoot (2020)
Journal Article

In the root, meristem and elongation zone lengths remain stable, despite growth and division of cells. To gain insight into zone stability, we imaged individual Arabidopsis thaliana roots through a horizontal microscope, and used image analysis to ob...

Uncovering the hidden half of plants using new advances in root phenotyping (2018)
Journal Article

© 2018 The Authors Major increases in crop yield are required to keep pace with population growth and climate change. Improvements to the architecture of crop roots promise to deliver increases in water and nutrient use efficiency but profiling the r...

A mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate (2018)
Journal Article

Phosphate (P) is an essential macronutrient for plant growth. Roots employ adaptive mechanisms to forage for P in soil. Root hair elongation is particularly important since P is immobile. Here we report that auxin plays a critical role promoting root... Read More about A mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate.

Shaping 3D root system architecture (2017)
Journal Article

Plants are sessile organisms rooted in one place. The soil resources that plants require are often distributed in a highly heterogeneous pattern.
