摘要： Sphingolipids (lipids with a sphingoid base backbone) are important components of eukaryotic membrane systems and key signaling molecules that are essential for controlling cellular homeostasis, acclimating to stress, and regulating plant immunity. Studies using sphingolipid treatments, measuring sphingolipids in infected plants, and functionally studying sphingolipid biosynthetic mutants demonstrated that sphingolipids participate in plant cell death and defense responses. In this review, we present an updated map of sphingolipid signaling and review recent progress in understanding the functions of sphingolipids in plant immunity as structural components of biological membranes, and as mediators of defense signaling. Moreover, several pressing questions, such as how sphingolipids in the plasma membrane, particularly microdomains, act to perceive pathogens and transduce signals during plant-pathogen interactions, remain to be further explored in future research.
