They’re so acidic
Who? Root cells. At least that’s what an apoplastic pH sensor told us. Nicholay’s conclusion from mapping the correlations between apoplastic pH, cell elongation and cell differentiation: cell wall pH …

It’s a balancing act
Paradoxes lingering around our lab ever since we started working on CLE peptide signaling finally resolved, at least genetically. Is CLE signaling always detrimental to phloem formation and differentiation? Or …

Double trouble CLE peptide signaling
Our latest nearly-back-to-back outputs in Current Biology and Nature Communications: for years we have known that autocrine CLE45 peptide signaling via its receptor BAM3 suppresses protophloem sieve element differentiation. What …

Drilling down on OPS function
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 …
