This weeks Arabidopsis Research Roundup begins with a study from SLCU that investigates the interaction between nitrate and cytokinin signaling in the shoot meristem. Next is research from Sheffield that studies changes to the macromolecular composition of the photosynthetic apparatus following the transition from dark to light. Third are three papers that include University of Edinburgh faculty members as co-authors; Gary Loake is involved in a global study on NO signaling, Karen Halliday is included on a study into the relationship between clock components and the PIF-mediated hypocotyl...

This weeks Arabidopsis Research Roundup begins with two papers from Royal Hollaway University of London that investigate the factors that control leaf development in the dark and the control of PIN1 phosphorylation. Third is a paper from Bristol that demonstrates the translation of research from Arabidopsis into coriander with regard the control of the response to UV light. Next is research from the John Innes Centre that characterises the role of DNA methylation during meiosis in the male lineage.

Christine Foyer (Leeds) leads the next paper that defines the relationship between...

This Arabidopsis Research Roundup covers the final papers of 2017 and the first of this new year. The initial paper is led by researchers in Bristol and characterises how the multifaceted BIG protein influences stomatal dynamics in response to altered CO2. Second is a manuscript from SLCU that for the first time in plants demonstrates nuclear sequestration of cell cycle regulated mRNAs.

Next is a paper from Rothamsted that describes a role for the hormone GA during floral development. David Salt (Nottingham) is then a co-author on a manuscript that has determined a role for the CTL...

This festive Arabidopsis Research Roundup begins with a commentary article from a global consortium of plant scientists who propose a framework of future training for researchers who will take advantage of the experimental tools available in Arabidopsis. Secondly is study from Caroline Dean (JIC) that defines the role of the LHP1 protein in epigenetic control of gene expression. Thirdly John Doonan (Aberystwyth) is a co-author of work that defines an important component of mitotic spindle formation. Next is a study led by Zinnia Gonzalez-Carranza in Nottingham that offers further insights...

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...

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...
