CEPLAS PhD student <link _blank internal-link-new-window internen link in neuem>Gwendolyn Kirschner is first author in the recent publication about „Unique and Conserved Features of the Barley Root Meristem“. This study revealed cell differentiation mechanisms in barley roots, but as well focussed on meristem development in the model organism Arabidopsis thaliana. The research groups from Heinrich Heine University Düsseldorf respectively from Max-Planck Institute for Plant Breeding Research were able to show that there are different mechanisms in monocot plants (e.g. barley) that control fate of root cap cells than in dicots (e.g. Arabidopsis).

Former CEPLAS postdoc <link internal-link-new-window internen link in neuem>Wilma van Esse and CEPLAS Gradschool member <link internal-link-new-window internen link in neuem>Agatha Walla share first authorship in a new Plant Physiology Paper. Their aim is to identify genes and pathways that control seed number in barley, which is a prerequisite to understand the relationship between genotype and phenotype. In barley, seeds can be arranged either in two or six rows which is controlled by transcriptional factors. In this study entitled „Six-Rowed Spike3 (VRS3) Is a Histone Demethylase That Controls Lateral Spikelet Development in Barley“ the investigators from Düsseldorf, Cologne and Wageningen (Netherlands) present a fast and efficient gene identification method, which does not require prior recombination or analysis of mapping populations and enables functional analysis in barley.
