Plastoglobules are plant lipid bodies localized inside plastids. They have long been considered as mere lipid storage compartments. However, ultrastructural and proteomic data now suggest their involvement in various metabolic pathways, notably the biosynthesis of tocopherols. In this work, the current knowledge on the structure and functions of plastoglobules is reviewed. On the basis of similarities between plastoglobules and seed oleosomes, the potential of plastoglobules for bioengineering applications is discussed.
质体小球是存在于质体内的植物脂质体。长期以来，它们一直被视为单纯的脂质储存区室。然而，超微结构和蛋白质组学数据现在表明它们参与各种代谢途径，特别是生育酚的生物合成。在这项工作中，对质体小球的结构和功能的现有知识进行了综述。基于质体小球与种子油体之间的相似性，讨论了质体小球在生物工程应用中的潜力。
