Rice ( L.), as one of the most significant food crops worldwide, holds paramount importance for global food security. Throughout its extensive evolutionary journey, rice has evolved a diverse array of defense mechanisms to fend off pest and disease infestations. Notably, labdane-related diterpenoid phytoalexins play a crucial role in aiding rice in its response to both biotic and abiotic stresses. This article provides a comprehensive review of the research advancements pertaining to the chemical structures, biological activities, and biosynthetic pathways, as well as the molecular regulatory mechanisms, underlying labdane-related diterpenoid phytoalexins discovered in rice. This insight into the molecular regulation of labdane-related diterpenoid phytoalexin biosynthesis offers valuable perspectives for future research aimed at improving crop resilience and productivity.
水稻（Oryza sativa L.）作为全球最重要的粮食作物之一，对全球粮食安全至关重要。在其漫长的进化历程中，水稻进化出了多种防御机制来抵御病虫害侵袭。值得注意的是，与半日花烷相关的二萜类植保素在帮助水稻应对生物和非生物胁迫方面发挥着关键作用。本文全面综述了水稻中发现的与半日花烷相关的二萜类植保素的化学结构、生物活性、生物合成途径以及分子调控机制等方面的研究进展。对与半日花烷相关的二萜类植保素生物合成的分子调控的深入了解，为未来旨在提高作物抗逆性和生产力的研究提供了有价值的视角。
