Fluctuations in auxin levels depend upon synchronicity of cell divisions in a one-dimensional model of auxin transport (2023)
Journal Article

Auxin is a well-studied plant hormone, the spatial distribution of which remains incompletely understood. Here, we investigate the effects of cell growth and divisions on the dynamics of auxin patterning, using a combination of mathematical modelling...

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...

Systems approaches reveal that ABCB and PIN proteins mediate co-dependent auxin efflux (2022)
Journal Article

Members of the B family of membrane-bound ATP-binding cassette (ABC) transporters represent key components of the auxin-efflux machinery in plants. Over the last two decades experimental studies have shown that modifying ABCB expression affects auxin...

Non-cell autonomous and spatiotemporal signalling from a tissue organizer orchestrates root vascular development (2021)
Journal Article

During plant development, a precise balance of cytokinin is crucial for correct growth and patterning, but it remains unclear how this is achieved across different cell types and in the context of a growing organ. Here we show that in the root apical... Read More about Non-cell autonomous and spatiotemporal signalling from a tissue organizer orchestrates root vascular development.

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...

A network of transcriptional repressors modulates auxin responses (2020)
Journal Article

The regulation of signalling capacity, combined with the spatiotemporal distribution of developmental signals themselves, is pivotal in setting developmental responses in both plants and animals. The hormone auxin is a key signal for plant growth and... Read More about A network of transcriptional repressors modulates auxin responses.

The CEP5 peptide promotes abiotic stress tolerance, as revealed by quantitative proteomics, and attenuates the AUX/IAA equilibrium in Arabidopsis (2020)
Journal Article

Peptides derived from non-functional precursors play important roles in various developmental processes, but also in (a)biotic stress signaling. Our (phospho)proteome-wide analyses of C-terminally encoded peptide 5 (CEP5)-mediated changes revealed an...

A core mechanism for specifying root vascular pattern can replicate the anatomical variation seen in diverse plant species (2019)
Journal Article

Pattern formation is typically controlled through the interaction between molecular signals within a given tissue.
