Amide signaling compounds contribnute to plant stress adaptation

The important role of endocannabinoid lipid signaling molecules, such as anandamide, and its CB receptors in numerous aspects of mammalian behavior, including the regulation of pain and inflammational processes, is well established. Here, fatty acid amide hydrolases (FAAH) from the amidase signature (AS) family terminate the signaling properties of the bioactive amides through their hydrolysis into free acids and amines. With respect to recent findings, plants also possess AS family proteins and bioactive amide signaling molecules, although their mode of action and physiological importance is less well studied. In this review article, we summarized the latest findings on two AS family members from Arabidopsis thaliana, FAAH and AMI1. Moreover, we present a model regarding their potential implication in regulating plant adaptations to abiotic stresses in plants.
