How do plants defend themselves at the molecular level? This comprehensive review explores the lipoxygenase pathway, a crucial component of plant defense mechanisms. From synthesis of hydroperoxy fatty acids to the generation of signaling compounds and antimicrobial agents, the research examines the pathway's role in plant interactions with pathogens, insects, and abiotic stress. The insights reveal how plants utilize lipid peroxidation to produce a diverse array of defense compounds. Cloning of many lipoxygenases and other key enzymes within the lipoxygenase pathway, as well as analyses by reverse genetic and metabolic profiling, revealed new reactions and the first hints of enzyme mechanisms, multiple functions, and regulation. A plant-specific blend of volatiles including leaf alcohols are among the numerous products. Ultimately, this review enhances our understanding of plant immunity and stress responses, offering potential avenues for improving crop resilience and developing sustainable agricultural practices. By unraveling the complexities of the lipoxygenase pathway, this research opens new horizons for engineering plant defenses and enhancing crop productivity.
Annual Review of Plant Biology publishes comprehensive reviews related to molecular plant biology. Thus, this review provides an overview of the lipoxygenase pathway. This fits the journal well, offering a holistic view of complex plant immunity.
