New hypothesis paper on secretion of small proteins published in Plant Signaling and Behavior

Small secreted proteins play an important role in plant development, as well as in reactions to changes in the environment. Our survey of the existing literature for the pathogenesis-related (PR) 1-like and Clavata3/Endosperm Surrounding Region (CLE) families showed a lack of details on their localization, trafficking, and exocytosis. Therefore, in order to uncover the modes of their secretion, we tested the hypothesis that a direct link between the secreted cargoes and the secretion regulators such as Rab GTPases, SNAREs, and exocyst subunits could be established using in silico co-expression and clustering approaches.
