The Sulfated PSY Peptide Negatively Regulates Receptor Kinase Activity to Promote Growth

Devin V. Tulio, Alexandra M. Shigenaga, Dawn Lim, Artur Teixeira de Araújo, Shu‐Zon Wu, Pamela C. Ronald, Magdalena Bezanilla

In Physcomitrium patens, genetic evidence suggests sulfated PSY peptide binding inactivates its receptor kinases rather than activating them; kinase-dead receptors rescue tpst mutants, while receptor overexpression phenocopies loss of sulfation.
