Plants express a diverse repertoire of functionally and structurally distinct antimicrobial peptides (AMPs) which provide innate immunity by acting directly against a wide range of pathogens. AMPs are expressed in nearly all plant organs, either constitutively or in response to microbial infections. In addition to their direct activity, they also contribute to plant immunity by modulating defence responses resulting from pathogen-associated molecular pattern/effector-triggered immunity, and also interact with other AMPs and pathways involving mitogen-activated protein kinases, reactive oxygen species, hormonal cross-talk and sugar signalling. Such links among AMPs and defence signalling pathways are poorly understood and there is no clear model for their interactions. This article provides a critical review of the empirical data to shed light on the wider role of AMPs in the robust and resource-effective defence responses of plants.
