Plant oils represent an energy-rich and carbon-dense group of hydrophobic compounds. These oils are not only of economic interest, but also play important, fundamental roles in plant and algal growth and development. The subcellular storage compartments of plant lipids, referred to as lipid droplets (LDs), have long been considered relatively inert oil vessels. However, research in the last decade has revealed that LDs play far more dynamic roles in plant biology than previously appreciated, including transient neutral lipid storage, membrane remodeling, lipid signaling, and stress responses. Here we discuss recent developments in the understanding of LD formation, turnover and function in land plants and algae.
植物油脂是一类富含能量且碳密度高的疏水分子化合物。这些油脂不仅具有经济价值，而且在植物和藻类的生长和发育中起着重要的基础作用。植物脂类的亚细胞储存室，称为脂滴（LDs），长期以来一直被认为是相对惰性的油容器。然而，过去十年的研究表明，LD 在植物生物学中的作用远比以前认为的更为活跃，包括瞬时中性脂质储存、膜重塑、脂质信号转导和应激反应。在这里，我们讨论了近年来对陆生植物和藻类中 LD 形成、周转和功能的理解的最新进展。
