This weeks Arabidopsis research roundup begins with a paper led by CPIB at the University of Nottingham that discovers a somewhat surprisingly mechanism controling Arabidopsis root hydrotropism. Next are two papers from the University of Leeds that firstly investigate how the JAGGED LATERAL ORGANS gene influences the auxin response and secondly looks at the role of redox regulation in the control of the cell cycle and seed development. Finally are two papers that look at different aspects of the plant pathogen interactions. Jonathan Jones from the John Innes Centre is a co-author on a...

This weeks Arabidopsis Research Roundup is lead by two papers that characterise the relationship between cell size and growth in different Arabidopsis tissues. Firstly the lab of GARNet PI Jim Murray look at how the cell cycle influences cell size progression in the SAM whilst George Bassel’s group from Birmingham investigate cell growth within a developing embryo. Thirdly is a paper from the University of Essex that further defines the role of the CP12 protein in control of photosynthesis. Next is a paper from researchers from the University of Warwick who lead a fascinating piece of ...

This bumper edition of the Arabidopsis Research Roundup includes a wide range of research topics. Firstly Mike Roberts leads a study that adds another layer of complexity to our understanding of the factors that control seed dormancy. Secondly a paper from Ottoline Leyser’s lab at SLCU provides more details regarding the role of BRC1 during shoot branching. Next is a paper that continues David Salt’s collaborative work that aims to understand how the root endodermal barrier influences nutrient uptake. Fourthly is work from Bristol that looks at the interaction between viral infection, the...

This weeks UK Arabidopsis Research Roundup includes three papers featuring researchers from the University of Nottingham as well as manuscripts from Leeds, Lancaster, QMUL and The Sainsburys Lab in Norwich

Firstly Stefan Kepinski (Leeds) leads a study that investigates how Gravitropic Set Point Angle (GSA) is controlled in response to different growth factors. Secondly are two Methods papers featuring researchers from CPIB in Nottingham, the first of which is in collaboration with Lancaster University and introduces the Microphentron, which is an automated phenotyping platform that...

This weeks Arabidopsis Research Roundup includes four papers that focus on different aspects of plant cell biology. Firstly Ian Henderson’s research group in Cambridge defines the role of a critical component that determines crossover frequency in plants and other eukaryotes. Secondly Karl Oparka (Edinburgh) leads a broad collaboration that defines the mechanism of unloading of solutes and macromolecules from the root phloem. Thirdly Keith Lindsey (Durham) has developed a model that describes how auxin patterns the Arabidopsis root. Finally Mike Blatt (Glasgow) is part of a group that uses...

This weeks research roundup includes just three papers and includes a study from the University of Essex that looks at the growth response of Arabidopsis plants to ‘real-life’ fluctuations in light levels. Secondly is a very different type of study from the University of York that uses Arabidopsis as a model for the development of plants that are able to accumulate catalytically active and commercially viable levels of palladium. Finally is a Chinese-led study that includes Alan Marchant (University of Southampton) as a co-author and...

This weeks Arabidopsis Research Roundup begins with two papers that look at endogenous and exogenous causes of cell proliferation. Firstly Mike Bevan (JIC) leads a team that looks into the role of controlled protein degradation in this process whilst secondly, Peter Etchells from Durham is a co-author on a study that investigates how nematode pathogens stimulate cell proliferation at the site of infection.

Thirdly is work featuring Cyril Zipfel and colleagues from TSL that looks at how autophosphorylation controls the activity of calcium dependent protein kinases. Fourthly is a...

This weeks Arabidopsis Roundup again includes a broad selection of research topics. Firstly researchers at SLCU are involved in work that describes Arabidopsis sepal development. Secondly Cyril Zipfel from TSL leads a study that adds a layer of complexity to our knowledge of cellular pathogen perception. Thirdly the group of Reiner van der Hoorn from Oxford introduces the use of a novel set of inhibitors that reveals differential activity of proteosomal subunits during bacterial infection. Finally Hugh Pritchard from Kew Gardens is a co...

Todays Arabidopsis Research Roundup includes some excellent examples of UK labs engaged in collaborative work with researchers from around the globe. However first up is a study solely from the John Innes Centre, led by Vinod Kumar, that investigates the role of PIF4 during the thermosensory response. Secondly David Evans (Oxford Brookes University) is a co-author on a French-led study that has looked into the role of LINC complexes during interphase heterochromatin patterning. Thirdly is the description of the new PhenoTiki imaging tool that has come from the lab of Sotirios Tsaftaris in...

The first Arabidopsis Research Roundup of 2017 includes a wide range of studies that use our favourite model organism.

Firstly Kerry Franklin (University of Bristol) is the corresponding author on a paper that describes the complex interaction between the responses to sunlight and heat. Secondly Paul Dupree (University of Cambridge) leads a study that defines the important structural relationship between xylan and cellulose. Thirdly members of Gos Micklem’s group in Cambridge are part of the Araport team that present their ThaleMine tool.

Richard Napier (University of Warwick...

The final Research Roundup of 2016 includes two papers that take different strategies toward the ultimate aim of crop improvement and use Arabidopsis as a tool for their initial discoveries. Firstly Christine Raines (University of Essex) uses a transgenic approach to upregulate enzymes of the calvin cycle while researchers from Rothamstead and Oxford use a chemical intervention strategy. Both of these strategies are successful in increasing yield.

Second are a set of back-to-back papers featuring Xiaoqi Feng (JIC) that investigate DNA methylation patterns in both male and female...
