A mixed selection of research in this UK Arabidopsis Roundup. Firstly a study from Stefan Kepinski and Mark Estelle that adds another layer of understanding to the regulation of the auxin response. Enrique Lopez-Juez leads a study into signaling between the nucleus and chloroplast while Tracey Lawson contributes to an investigation into role of starch metabolism in guard cells. Fran Maathuis and co-worker looks at differences in vacuolar transport between Arabidopsis ecotypes while Alan Marchant is involved in a study of cell wall pectins. Finally William Amos has uses the 1001genomes...

For the inaugural Arabidopsis Research Roundup of 2016 we feature the final publications of UK researchers from 2015. Martin Howard kindly provides an audio description of a paper that looks at a fundamental aspect of transcriptional regulation, through the lense of the FLC gene, whilst his co-author Caroline Dean on that paper is an author on another manuscript that investigates RNA stability in the same FLC locus. Katja Graumann leads a paper that looks into gene expression at the periphery of the nucleus whilst Ian Colbeck looks at the effect of silver...

The final Arabidopsis Research Roundup of 2015 contains a bumper crop of papers that again highlights the diversity of research occuring in UK plant science. Justin Goodrich from the University of Edinburgh kindly provides an audio description of work that identifies a novel role for a member of a transposon gene family. Elsewhere are studies about a specific aspect of the biochemistry of crytochromes as well as confirmation of a role for DNA gyrases in Arabidopsis. Paul Dupree (Oxford) leads a study into the mechanism of ascorbic acid production while Heather Knight is the UK...

This December 9th Arabidopsis Research Roundup includes four rather different studies. Firstly we include an excellent audio description from David Salt about a new type of GWAS analysis that his lab was involved in developing. This allowed identification of new genetic loci involved in molybdenum signalling. Secondly Isabelle Carre’s group from Warwick presents a study into the interactions that define the functioning of the circadian clock. Thirdly Mike Blatt leads a study that models stomatal opening and finally we include an investigation of the DOG1 gene, that includes a contribution...

This weeks Arabidopsis Research Roundup contains four papers each with a different focus. Firstly is a large-scale investigation that attempts to define the transcriptional changes that occur in response to bacterial infection. Second is a study that investigates a newly proposed role for the chloroplast chaperone Hsp93. Thirdly is another piece of work that also involves University of Oxford researchers and investigates the genetic networks that control leaf morphology. Finally is an updated plant-specific protocol for the commonly used technique of Chromatin Immunoprecipitation.

This weeks Arabidopsis Research Roundup presents a wide range of topics from researchers across the UK. Firstly we highlight a study that documents the early stages of a potential biotechnological/synthetic biology approach to improve higher plant photosynthesis using algal components. Corresponding author Alistair McCormick also takes five minutes to discuss this work. Secondly a team based mostly at Bath introduces the function of the PAT14 gene, which is involved in S-palmitoylation. Thirdly is a study that successfully transfers SI...

Academics from the John Innes Centre lead two of the papers featured in this week Arabidopsis Research Roundup. Firstly Veronica Grieneisen leads a study that combines modeling and experimental work to assess the factors that establish the root auxin maximum and secondly the structural biologist David Lawson heads up an investigation into the plastid-localised enzyme, DPE1. Seemingly a common theme in UK-Arabidopsis research focuses on the factors that control the dynamics of stomatal opening and this week Mike Blatt from Glasgow heads a team that investigates...

There are just three research papers in this weeks Arabidopsis Roundup but they each represent important projects from established groups. Firstly is a significant output from the Edinburgh SynthSys Centre that documents their analysis of the Arabidopsis circadian clock. Secondly an international collaborative effort looks into the molecular signaling pathways that control the physiological response to increasing CO2 levels and thirdly a paper that uncovers a novel plant-specific molecular mechanism that controls the biogenesis of certain siRNAs. Finally we...

The Arabidopsis Research Roundup is ‘defense-focused’ this week. We present three papers that highlight different aspects of plant immunity, two of which result from UK-US-China collaborations. Firstly a team from the Sainsbury Lab, Norwich looks at two molecular mechanisms that control stomatal closure. There are then two studies that involve University of Exeter researchers that investigate either the role of plant hormones in the response to bacterial pathogens or the role that the physical barrier of the cell wall plays in the...

This weeks Arabidopsis Research Roundup includes papers, from Glasgow and Oxford, that look at a plants response to different abiotic stresses and uncover control mechanisms that might have potential as targets for future genetic modification or gene-editing strategies. In addition there is a study from Leeds that uncovers a novel molecular mechanism in the DNA repair pathway and finally an international group of researchers with a UK lead at Kings College use infrared microspectroscopy to investigate internal cellular structures

After a slow couple of weeks the Arabidopsis Research Roundup returns with some publications in high profile journals. None more so than the widely reported study from the University of York that highlights Arabidopsis plants which are able to grow on TNT-contaminated soils. Three other broadly cell biology-based studies from the JIC, Cardiff and Nottingham look at cell wall composition, vascular patterning and polyadenylation respectively. Finally a study from the James Hutton Institute presents an improved tool for identification of DNA-binding...
