Plant endogenous signaling peptides shape growth, development and adaptations to biotic and abiotic stress. Here, we identify C-TERMINALLY ENCODED PEPTIDEs (CEPs) as immune-modulatory phytocytokines in Arabidopsis thaliana. Our data reveals that CEPs induce immune outputs and are required to mount resistance against the leaf-infecting bacterial pathogen Pseudomonas syringae pv.

We discuss data from studies in which we attempted to create conditions in which interdependent gains overlapped with individual reinforcement schedules so that these situations were more or less competitive and conflicting. We argue that normative rules about reinforcement schedules and interdependent reinforcement are crucial for analyzing social behavior since these rules allow us to differentiate the effects of individual and social contingencies or an interaction of both.
