Anandamide (NAE 20:4) or arachidonlyethanolamine (AEA) is the most widely studied N-acylethanolamine (NAE) because it mediates several physiological functions in mammals. In vascular plants, 12-18C NAEs inhibit growth in an abscisic acid (ABA)-dependent and -independent manner. Anandamide, which is unique to bryophyte Physcomitrella patens, inhibited gametophyte growth and reduced chlorophyll content when applied exogenously. It is hypothesized that anandamide mediates its responses through morphological and cellular changes. Following growth inhibition by short-term anandamide-treatment, microscopic analyses revealed relocated chloroplasts and depolymerized F-actin in protonemal tips. Long-term treatment showed partially bleached gametophyte cells with degraded and browning chloroplasts. These anandamide-mediated responses have physiological implications as AEA may function as a signal for gametophytes to activate secondary dormancy as seen with ABA. Future studies will investigate the role of AEA in mediating stress responses and possible interaction with ABA.
