The first intron of ARF7 is required for expression in root tips (2024)
Journal Article

Auxin regulates plant growth and development through the transcription factors of the AUXIN RESPONSE FACTOR (ARF) gene family. ARF7 is one of five activators that bind DNA and elicit downstream transcriptional responses. In roots, ARF7 regulates grow...

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...

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...

Uncovering How Auxin Optimizes Root Systems Architecture in Response to Environmental Stresses (2021)
Journal Article

Since colonizing land, plants have developed mechanisms to tolerate a broad range of abiotic stresses that include flooding, drought, high salinity, and nutrient limitation. Roots play a key role acclimating plants to these as their developmental pla... Read More about Uncovering How Auxin Optimizes Root Systems Architecture in Response to Environmental Stresses.

Auxin fluxes through plasmodesmata modify root-tip auxin distribution (2020)
Journal Article

© 2020. Published by The Company of Biologists Ltd. Auxin is a key signal regulating plant growth and development. It is well established that auxin dynamics depend on the spatial distribution of efflux and influx carriers on the cell membranes. In t...

Cell Death in Cells Overlying Lateral Root Primordia Facilitates Organ Growth in Arabidopsis (2020)
Journal Article

© 2019 The Authors Plant organ growth is widely accepted to be determined by cell division and cell expansion, but, unlike that in animals, the contribution of cell elimination has rarely been recognized. We investigated this paradigm during Arabidop... Read More about Cell Death in Cells Overlying Lateral Root Primordia Facilitates Organ Growth in Arabidopsis.

PUCHI regulates very long chain fatty acid biosynthesis during lateral root and callus formation (2019)
Journal Article

© 2019 National Academy of Sciences. All rights reserved. Lateral root organogenesis plays an essential role in elaborating plant root system architecture. In Arabidopsis, the AP2 family transcription factor PUCHI controls cell proliferation in later...

EXPANSIN A1-mediated radial swelling of pericycle cells positions anticlinal cell divisions during lateral root initiation (2019)
Journal Article

In plants, postembryonic formation of new organs helps shape the adult organism. This requires the tight regulation of when and where a new organ is formed and a coordination of the underlying cell divisions. To build a root system, new lateral roots...

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.

Dynamic regulation of auxin oxidase and conjugating enzymes AtDAO1 and GH3 modulates auxin homeostasis (2016)
Journal Article

Auxin is a key hormone regulating plant growth and development. We combine experiments and mathematical modeling to reveal how auxin levels are maintained via feedback regulation of genes encoding key metabolic enzymes. We describe how regulation of...

Dioxygenase-encoding AtDAO1 gene controls IAA oxidation and homeostasis in arabidopsis (2016)
Journal Article

Auxin represents a key signal in plants, regulating almost every aspect of their growth and development. Major breakthroughs have been made dissecting the molecular basis of auxin transport, perception, and response. In contrast, how plants control t...
