Carotenoids are a diverse group of pigments widely distributed in nature. The vivid yellow, orange, and red colors of many horticultural crops are attributed to the overaccumulation of carotenoids, which contribute to a critical agronomic trait for flowers and an important quality trait for fruits and vegetables. Not only do carotenoids give horticultural crops their visual appeal, they also enhance nutritional value and health benefits for humans. As a result, carotenoid research in horticultural crops has grown exponentially over the last decade. These investigations have advanced our fundamental understanding of carotenoid metabolism and regulation in plants. In this review, we provide an overview of carotenoid biosynthesis, degradation, and accumulation in horticultural crops and highlight recent achievements in our understanding of carotenoid metabolic regulation in vegetables, fruits, and flowers.
类胡萝卜素是一类广泛分布于自然界的色素。许多园艺作物鲜艳的黄色、橙色和红色归因于类胡萝卜素的过度积累，类胡萝卜素是花卉的关键农艺性状以及水果和蔬菜的重要品质性状。类胡萝卜素不仅赋予园艺作物视觉吸引力，还能提高其对人类的营养价值和健康益处。因此，在过去十年中，园艺作物中的类胡萝卜素研究呈指数级增长。这些研究推进了我们对植物类胡萝卜素代谢和调控的基本认识。在本综述中，我们概述了园艺作物中类胡萝卜素的生物合成、降解和积累，并重点介绍了我们在理解蔬菜、水果和花卉中类胡萝卜素代谢调控方面的最新成果。
