New research from our lab in collaboration with Ruediger Simon’s group at Heinrich-Heine University Duesseldorf, Germany, suggests that the enigmatic OPS protein interferes with CLE45 signaling by directly disturbing the interactions of CLE45 receptor components. Highlighting the exquisitely quantitative aspect of OPS action, a genetic game combining higher or lower OPS activity with higher or lower CLE45 pathway activity demonstrates the in vivo relevance of our findings.

A first chapter of Alja’s Ph.D. thesis: “Broad spectrum developmental role of Brachypodium AUX1”. And some counter-intuitive phenotypes in the Bdaux1 mutant, like surprisingly long roots.
The culmination of persistent, patient, phantastic collaboration with the labs of Claus Schwechheimer and Uli Hammes at the Technical University of Munich. It allowed us to pin down the nearly 10-year-old notion that BRX modulates polar auxin transport at the plasma membrane. It does, in conjunction with the PAX kinase! Of course, none of this would have been possible without the exceptional experimental skills of Petra & Lana et al…
We are delighted that Pietro’s artistic root cross sections were chosen as the cover for the September 2017 issue of Plant & Cell Physiology! They illustrate his article on the role of the BIG BROTHER gene in root development, published in the same issue.
Pietro’s paper on the underground role of the BIG BROTHER gene in organ size restriction published!
Especially if it ends up in a publication. Latest from our lab & collaborators highlights CLE peptide receptor action in the root protophloem (and also cautions against background mutations…).
On the role of brassinosteroid signaling in root meristem development. Including our probably most spectacular result from a reviewer-imposed (…and justified) control experiment: Fig. 5. Also see this highlight in Development.
