植物类胡萝卜素是一类参与光收集的色素，对防止过量光的光保护至关重要。此外，它们是类胡萝卜素激素（如脱落酸和独角酯内酯）产生的前体。在这篇综述中，我们总结了目前对类胡萝卜素生物合成途径的基因和酶的了解（现在几乎完全阐明），以及在转录和转录后水平上对类胡萝卜素生物合成的调控。我们还讨论了拟南芥作为胡萝卜素生成研究的模型系统的相关性，以及这种植物的代谢工程方法如何为类胡萝卜素生物技术提供了重要的经验教训。
Plant carotenoids are a family of pigments that participate in light harvesting and are essential for photoprotection against excess light. Furthermore, they act as precursors for the production of apocarotenoid hormones such as abscisic acid and strigolactones. In this review, we summarize the current knowledge on the genes and enzymes of the carotenoid biosynthetic pathway (which is now almost completely elucidated) and on the regulation of carotenoid biosynthesis at both transcriptional and post-transcriptional levels. We also discuss the relevance of Arabidopsis as a model system for the study of carotenogenesis and how metabolic engineering approaches in this plant have taught important lessons for carotenoid biotechnology.
