Many small peptides that serve as important signaling molecules have been identified in animals, and more recently similar molecules have been recognized in plants. Matsubayashi et al. have now identified the likely receptor for a sulfated peptide, phytosulfokine, in carrot cells. The protein is a receptor kinase with a single transmembrane domain and features leucine-rich repeats in the extracellular domain. Interactions between the phytosulfokine and its receptor regulate proliferative and regenerative ability of the plant tissues.
