Just three papers in this weeks Arabidopsis Research Roundup and they each cover fundamental aspects of the hormone and environmental control of gene expression. First Keith Lindsey provides an audio description of work that aims to dissect the complex hormonal regulation of root growth while secondly, Nick Harberd is involved in a study that investigates the HY5 shoot-root signaling protein. Finally Ian Graham leads a study into factors that regulate seed dormancy.

This weeks Arabidopsis Research Roundup features papers that build upon the history of research in each featured lab. Firstly Gareth Jenkins from Glasgow continues to investigate mechanisms of UV-B signaling whilst Laila Moubayidin, now at the JIC, is involved in work that investigates the multiple factors that control root meristem size. Finally we present a three protocol papers that are featured in a new colelction of articles that focus on protocols that can be used to assess different environmental responses.

It has been a quiet couple of weeks for newly published UK Arabidopsis Research but what might be lacking in quantity is made up for in quality! Firstly the PRESTA consortium use gene regulatory network analysis to identify a key component in the response to drought stress. Secondly is a paper featuring researchers from Rothamstead that identifies a new molecular participant in the control of RNA surveillance. Thirdly is a paper that investigates the function of aquaporins during lateral root emergence and includes researchers from Warwick and Nottingham. Finally is a study from Sheffield...

This weeks Arabidopsis Research Roundup features a paper from David Baulcombe and Joe Ecker that further deciphers mechanisms of RNA silencing and is kindly discussed by postdoc Mat Lewsey in a short audio description. Elsewhere there are three studies that include researchers from CPIB in Nottingham. Leah Band contributes to a study that links environment sensing, cell death and auxin signaling whilst Ive De Smet leads a study that finds new proteins involved in cell division. Malcolm Bennett and John King take a modeling approach to describe auxin signaling via the GH3 protein family....

A mixed selection of research in this UK Arabidopsis Roundup. Firstly a study from Stefan Kepinski and Mark Estelle that adds another layer of understanding to the regulation of the auxin response. Enrique Lopez-Juez leads a study into signaling between the nucleus and chloroplast while Tracey Lawson contributes to an investigation into role of starch metabolism in guard cells. Fran Maathuis and co-worker looks at differences in vacuolar transport between Arabidopsis ecotypes while Alan Marchant is involved in a study of cell wall pectins. Finally William Amos has uses the 1001genomes...

For the inaugural Arabidopsis Research Roundup of 2016 we feature the final publications of UK researchers from 2015. Martin Howard kindly provides an audio description of a paper that looks at a fundamental aspect of transcriptional regulation, through the lense of the FLC gene, whilst his co-author Caroline Dean on that paper is an author on another manuscript that investigates RNA stability in the same FLC locus. Katja Graumann leads a paper that looks into gene expression at the periphery of the nucleus whilst Ian Colbeck looks at the effect of silver...

The final Arabidopsis Research Roundup of 2015 contains a bumper crop of papers that again highlights the diversity of research occuring in UK plant science. Justin Goodrich from the University of Edinburgh kindly provides an audio description of work that identifies a novel role for a member of a transposon gene family. Elsewhere are studies about a specific aspect of the biochemistry of crytochromes as well as confirmation of a role for DNA gyrases in Arabidopsis. Paul Dupree (Oxford) leads a study into the mechanism of ascorbic acid production while Heather Knight is the UK...

This December 9th Arabidopsis Research Roundup includes four rather different studies. Firstly we include an excellent audio description from David Salt about a new type of GWAS analysis that his lab was involved in developing. This allowed identification of new genetic loci involved in molybdenum signalling. Secondly Isabelle Carre’s group from Warwick presents a study into the interactions that define the functioning of the circadian clock. Thirdly Mike Blatt leads a study that models stomatal opening and finally we include an investigation of the DOG1 gene, that includes a contribution...

This weeks Arabidopsis Research Roundup contains four papers each with a different focus. Firstly is a large-scale investigation that attempts to define the transcriptional changes that occur in response to bacterial infection. Second is a study that investigates a newly proposed role for the chloroplast chaperone Hsp93. Thirdly is another piece of work that also involves University of Oxford researchers and investigates the genetic networks that control leaf morphology. Finally is an updated plant-specific protocol for the commonly used technique of Chromatin Immunoprecipitation.

This weeks Arabidopsis Research Roundup presents a wide range of topics from researchers across the UK. Firstly we highlight a study that documents the early stages of a potential biotechnological/synthetic biology approach to improve higher plant photosynthesis using algal components. Corresponding author Alistair McCormick also takes five minutes to discuss this work. Secondly a team based mostly at Bath introduces the function of the PAT14 gene, which is involved in S-palmitoylation. Thirdly is a study that successfully transfers SI...

Academics from the John Innes Centre lead two of the papers featured in this week Arabidopsis Research Roundup. Firstly Veronica Grieneisen leads a study that combines modeling and experimental work to assess the factors that establish the root auxin maximum and secondly the structural biologist David Lawson heads up an investigation into the plastid-localised enzyme, DPE1. Seemingly a common theme in UK-Arabidopsis research focuses on the factors that control the dynamics of stomatal opening and this week Mike Blatt from Glasgow heads a team that investigates...
