There are a bumper crop of papers in this edition of the Arabidopsis Research Roundup. First from the University of Manchester is a paper that identifies a protein involved in plant programmed cell death. Secondly are two papers from the University of Bristol that highlight the role of viruses in the reflectivity of plant leaves and an assessment of the growth parameters of Arabidopsis on different soil-types. Thirdly are three papers from University of Edinburgh that either use CRISPR-Cas technology to develop virus-research plants, investigate the relationship between photoperiod and metabolism or present a method for assessment of protein S-nitrosylation. Fourthly is a paper that includes a contribution from the University of Leeds that investigates the evolutionary and functional relationship of the WOX gene family. Finally is a study that highlights the role of the AUGMIN complex during microtubule activity and that includes a contribution from the University of Leicester. In addition, although not involving Arabidopsis, we should mention an exciting study from Gerben van Ooijen (Edinburgh) that has discovered a conserved circadian mechanism based on magnesium rhythms that is linked to energy expenditure. http://goo.gl/J05Twh For more details on these papers: http://goo.gl/gdcjpn -- Please encourage your colleagues to sign up for the ArabUK Newsgroup.
