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...

This weeks Arabidopsis Research Roundup includes an exciting selection of papers that cross a range of subject areas. Firstly is a study led by George Bassel from Birmingham that details cell growth processes across the developing embryo. Secondly Henrik Jonsson at SLCU is a co-author on a study that adds to our understanding of the auxin signaling pathways that controls shoot phyllotaxis. Thirdly are two studies from the University of Oxford that investigate the evolution in land plants of either rooting systems or the response to KNOX transcription factors. Next Cyril Zipfel (TSL) is a...

This weeks Arabidopsis Research Roundup is led by a manuscript from Tom Bennett and Ottoline Leyser that looks at Strigolactone signaling for which Tom provides a brief audio description. Elsewhere Verena Kreichbaumer (Oxford Brookes) is a co-author on a study that looks into cytokinin control of auxin biosynthesis and Mike Blatt’s lab at the University of Glasgow continue to elucidate the role of SNARE proteins in vesicle formation. The penultimate paper includes Peter van Esse as a co-author of a study into the role of SERK proteins in the control of different signaling pathways. Finally...

A couple of weeks of inactivity leads to a bumper edition of the Arabidopsis Research Roundup.
Firstly are two papers from the JIC led by Janelle Balk and Caroline Dean that look at the regulation of the maturation of Fe-S protein complexes or of FLC expression respectively.
Secondly is a study from Liam Dolan in Oxford that looks at regulation of root-hair specific gene expression.
Thirdly is a paper from the University of Bristol that looks at the factors that control the regulation of plastid gene expression.
Fourth are a pair of papers that include work from...

This weeks Roundup demonstrates a wide breadth of research topics that use Arabidopsis as the model organism. Firstly Matthew Terry and colleagues investigate the factors that control reterograde signaling between chloroplast and nucleus. Secondly researchers from the University of Sheffield demonstrate that a component of the cell wall is involved in stomatal opening. Thirdly Malcolm Bennett and Ranjan Swarup from CPIB are co-authors on research that touches on a familiar topic, the regulation of the AUX1 protein in Arabidopsis roots. Fourthly Alastair Rutherford is a collaborator on a US...

This week Arabidopsis Research Roundup includes an audio description from Robert Sablowski about work from this lab that describes the early specification of stem tissue within the shoot apical meristem. In addition multiple members of CPIB in Nottingham are involved in two connected papers that describe how auxin homeostasis is controlled at the cell and tissue level. Researchers from the University of Bristol shed light on the relationship between viral infection and stomatal development whilst Claudius Marondedze from the University of Cambridge in involved in a study that has used next...

This weeks Arabidopsis Research Roundup includes an audio description provided by Katja Graumann from the Oxford Brookes Plant Endomembrane Group. Katja is involved in two of this weeks papers, the first of which describes the biology of a novel set of Nuclear Envelope (NE) localised proteins whereas the second is a phylogenetic analysis of a range of known NE-localised proteins. Elsewhere David Salt (CPIB) is the corresponding author on work that investigates the plants response to sulphur while David Twell (...

This weeks Arabidopsis Research Roundup includes a study from the University of Warwick investigating the role of the ubiquitin-proteasome system in the defense response. Secondly researchers from Warwick (again), Durham and Rothamsted are involved in a paper that links cell cycle progression to production of endomembranes. Finally are two studies that include researchers from Edinburgh that firstly provide an insight into the non-specific transport of molecules into the phloem and secondly looks at the cellular basis of endosperm breakdown.

The latter study is part of a special...

This addition of the Arabidopsis Research Roundup includes a broad range of research topics. At the cellular level is a study led by Malcolm Bennett (CPIB) that adds a layer of complexity to our understanding of lateral root development whilst Johnathan Napier (Rothamsted) is a co-author on an investigation into the function of fatty acid elongase complexes. At the tissue level John Christie (University of Glasgow) leads a study into the role of light signaling on hypocotyl development and David Salt (CPIB) contributes to the biomaging of ions along the Arabidopsis root. Finally at the...

This weeks Arabidopsis Research Roundup includes three papers across a wide range of topics. Firstly is a widely-reported study, described here with an audio description by Nik Cunniffe and Sanjie Ziang, of the evolutionary relationship between viral infection, pollinator attraction, plant fertility and miRNA-regulated gene expression. Secondly, Gordon Simpson is a co-author on a paper that has elucidated the crystal structure of the FPA proteins and finally Gareth Jenkins leads an investigation into the relationship between UV light, the UVR8 protein and histone modifications.

This weeks Arabidopsis Research Roundup includes broad representation from Norwich Research Park with Caroline Dean, Enrico Coen and Cyril Zipfel each leading studies that focus respectively on the regulation of transcriptional state, auxin patterning that defines leaf shape or the molecular basis of the PAMP response.

Elsewhere Liam Dolan (Oxford) leads, and Malcolm Bennett (CPIB) is the principal UK contributor on studies that look into different aspects of the key molecular signals in either root hair or lateral root development.

Finally Richard Napier is a co-author on a...
