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...

The Arabdopsis Research Roundup broadens its remit this week. As well as including three original research papers, which look at casparian strip formation, light and hormone signaling, we also highlight an important viewpoint article that aims to set standards for synthetic biology parts. In addition we include a meeting report from a plant synthetic biology summer school and interviews with plant scientists at the JIC, Caroline Dean and Anne Osbourn.

There are a wide array of topics included in this weeks Arabidopsis Research Roundup, ranging from studies on stomatal density, thylakoid transport, metabolic flux analysis, mutant detection and root development. We feature unlinked studies from three researchers from the University of Oxford Plant Science (Paul Jarvis, Lee Sweetlove and Nick Harberd), whilst the papers from Julie Gray and Brian Forde share the broad theme that investigates different mechanisms that might be used to improve nitrogen uptake, either by modifying the expression of a single gene involved in root development or...

The UK Arabidopsis Research Roundup this week includes a couple of EVO-DEVO-type studies that compare processes within different organisms (Physcomitrella and Cardamine) to those occurring in Arabidopsis. These include the evolution of both hormone signaling and leaf development. Elsewhere a cell-biological focused study looks at the factors that control formation of plasmodesmata whilst another manuscript investigates the details of a plants mechanism to avoid photoinhibition.

This weeks Arabidopsis Research Roundup bucks the recent trend of featuring large consortium-led studies as it contains four studies each from a single UK Institution. Matthew Jones (Essex) looks at the link between photosynthesis, the circadian clock and blue-light signaling whilst Miriam Gifford (Warwick) uses cell sorting to more precisely define the plants response to an oomycete pathogen. Elsewhere Peter Eastmond (Rothamstead) looks at lipid metabolism and Keith Lindsey (Durham) leads a theorectical study on the...

Two broad topics dominant the studies featured in this weeks Arabidopsis Research Roundup. Environmental and hormonal factors that control different types of ‘dormancy’ are presented in studies from the labs of Caroline Dean (JIC) and Ian Graham (York). Elsewhere two Sainsbury lab (Norwich) led studies investigate different aspects of the interaction between plants and bacterial pathogens. Finally Colin Turnbull from Imperial College is involved in an interesting assessment of cytokinin concentrations across the root tip.

There is a bumper crop of publications in high quality journals in this weeks UK Arabidopsis Research Roundup, including manuscripts in PNAS, Nature Communications, PLoS Genetics , PloS One and Plant Physiology. Malcolm Bennett, Alex Webb and Anthony Hall lead a major collaborative effort that links the circadian clock with lateral root formation whilst Ottoline Leyser (SLCU) and Mike Bevan (JIC) participate in a similarly broad consortium in a study linking organ size and MAPK signaling. Liam Dolan’s group from Oxford looks at...

A couple of weeks since the last update as it’s been quiet for UK Arabidopsis Research publications. However we now see a variety of publications that address some important questions in different signaling pathways. Firstly a multinational collaboration performs a genome-wide analysis of DELLA binding, followed by two studies looking different aspects of light signaling, specifically the link with the production of protective carotenoids and also with the tight control of protein degradation. Elsewhere there is the description of a...
