Arabidopsis thaliana RALF1 opposes brassinosteroid effects on root cell elongation and lateral root formation

The peptide RALF regulates cell expansion via an as-yet-unknown mechanism. Here, we provide evidence that AtRALF1 may be negatively regulating cell expansion by interfering with the brassinosteroid signalling pathway.
