Technical Abstract: Carotenoids are a diverse group of pigments widely distributed in nature. The vivid yellow, orange, and red colors in many horticultural crops attribute to overaccumulation of carotenoids, which contribute to a critical agronomic trait for flowers and an important quality trait for fruits and vegetables. Carotenoids not only give the horticultural crops their visual appeal, but also enhance their nutrition and health benefits to humans. As a result, an exponential growth on carotenoid research in horticultural crops has been observed over the last decade. These investigations advance 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 on our understanding of regulation of carotenoid metabolism in vegetables, fruits, and flowers.
