This weeks Research Roundup begins with two papers from the University of Edinburgh on very different topics of Arabidopsis research. Firstly Alistair McCormick and Sofirtios Tsaftaris introduce a new low-cost phenotyping platform whilst Gerben Ooijen’s group has analysed the role of SUMOylation in the control of the circadian clock. The next three papers each involve wide UK collaborations and either look at plant nutrient composition (Nottingham, Dundee, York), the role of N-end rule pathway in the control of seed storage mobilisation (Rothamsted, Nottingham, Oxford, Birmingham,...

The week’s UK Arabidopsis research roundup includes seven papers from groups who work on a range of topics.

Firstly Antony Dodd (Bristol) investigates the role of sugar signaling during hypocotyl elongation and provides an audio description of this groups work. Secondly Mike Holdsworth (Nottingham) leads a paper that demonstrates the importance of the N-rule pathway in the response to abiotic stresses. Thirdly are a set of papers that have developed models on three different topics. Mike Blatt’s group at Glasgow University has a cross-scale model that is applied to stomatal opening...

This weeks Research Roundup includes three research and two methods papers. Firstly is work from the O’Connor and Leyser groups at SLCU that investigates the diversity of function in PIN auxin transporters between monocots and dicots. Secondly research from the Kover lab at the University of Bath has characterised the photosynthetic contribution of the inflorescence stem whilst the third paper is from the Bill Finch-Savage at the University of Warwick and looks at the effect of temperature on seed dormancy. Finally are two methods paper from the University of Warwick and Leeds that...

Different aspects of plant cell wall biology dominant the first few papers of this weeks Arabidopsis Research Roundup. Firstly Andrew Fleming (University of Sheffield) and colleagues identify that a specific type of cell wall stiffening is important in control of stomatal opening. Secondly are two papers from the lab of Paul Dupree (University of Cambridge) that investigate the role that xylan modifications play in the formation of the cell wall. Finally in this broad area John Runions (Oxford Brookes) and colleagues show that attachment to the cell wall is critical for correct function of...

Daniel Pass (Cardiff University) discusses his recent paper published in PLoS Genetics entitled ‘Genome-wide chromatin mapping with size resolution reveals a dynamic sub- nucleosomal landscape in Arabidopsis’. Dan highlights his Github page where the code for the novel graphics in this paper are held.

After a brief hiatus the UK Arabidopsis Research Roundup returns with eight papers that focus on different aspects of Arabidopsis cell biology.

Firstly GARNet PI Jim Murray leads a study that performs a genome-wide analysis of sub-nucleosomal particles whilst Phil Wigge’s lab at SLCU conducts a more focused study on G-box regulatory sequences.

Thirdly Veronica Grieneisen (JIC) and co-workers have modelled the process of boron transport in the root, revealing exciting insights into how traffic jams might form.

Fourthly is a large scale biology paper led by Miriam...

This largest ever Arabidopsis Research Roundup (ARR) includes 6 papers from Norwich Research Park (NRP), including three featuring Cyril Zipfel (TSL) as a co-author on papers that investigate different aspects of plant immune signaling. Elsewhere on the NRP site Veronica Grieneisen (JIC) is a co-author on a study that defines the root auxin maximum whilst Dale Sanders and Saskia Hogenhout lead a paper that defines a method for the analysis of calcium signaling. Finally Robert Sablowski’s group at the JIC investigates the role of the...

There is a bumper crop of papers in this weeks UK Arabidopsis Research Roundup! First up is a remarkable piece of work from George Bassel’s (University of Birmingham) lab that defines the network of cellular interactions that occur in the hypocotyl. Second and third are papers from the JIC in which Lars Ostergaard’s group uncovers the extent of the ETTIN signaling network and Caroline Dean‘s and Martin Howard’s labs provide evidence for a two step progression toward stable gene silencing following vernalisation at the FLC locus. Fourthly is a study that includes members of Alex Webb’s...

This weeks UK Arabidopsis Research Roundup includes a study from the lab of GARNet Chairman Steven Spoel that describes their work on the control of ROS signaling. The other two papers looks at different aspects of photosynthetic control. Firstly Giles Johnson (University of Manchester) investigates the proteomic changes that occur during dynamic acclimation. Finally Alex Webb’s lab (University of Cambridge) investigate how the products of photosynthesis feed into ethylene-dependent control of the circadian clock.

This weeks Arabidopsis Research Roundup has a tools-focus as it includes three papers that highlight new tools that are available to the plant science community. Silke Robatzek (TSL) leads research that has developed software for analysis of subcellular fluorescent markers whilst in a broadly similar area Mark Fricker (University of Oxford) is part of an international collaboration that characterises a tool that allows for analysis of intracellular ATP concentrations. Thirdly Phillip White (JHI) leads a consortium that has developed computer-assisted software to aid automated phenotyping....

This weeks Arabidopsis Research Roundup includes four studies from around the UK. Firstly is a systems-level study of the drought response that includes Alessandra Devoto from RHUL as a co-author. Secondly Anne Osbourn’s group at the JIC investigates sesterterpenoid biosynthesis across plant species. Thirdly Paul Jarvis from Oxford University adds to this groups portfolio of research on the mechanisms that control thylakoid import. Finally Patrick Gallois (University of Manchester) provides further insight into the regulation of programmed cell death.
