Carotenoids are indispensable to plants and play a critical role in human nutrition and health. Carotenoids are pigments in plants, algae, and photosynthetic bacteria. For example, provitamin A carotenoids (α- and β-carotene) are the precursors of vitamin A, which plays a role in the prevention of blindness, xerophthalmia, and premature death. Carotenoids play essential roles in photosynthesis and photoprotection (. 0000011987 00000 n 0000006951 00000 n 0000025098 00000 n In this review, we summarize current knowledge of the genes and enzymes involved in carotenoid metabolism and describe recent progress in understanding the regulatory mechanisms underlying carotenoid accumulation. Therefore carotenoids, acting as light absorbing accessory pigments, have allowed to expand the range of solar radiation absorbed and so utilized for photosynthesis, energy that is then transferred to chlorophyll itself. Carotenoids are derived from 4 terpenes, including totally 40 carbon atoms. The core carotenoid pathway is conserved in most plant species although some plants accumulate special and rare carotenoids via unique biosynthetic routes. The importance of the specific location of carotenoid enzyme metabolons and plastid types as well as of carotenoid-derived signals is discussed.

Carotenoids have two important roles in photosynthetic organisms. 0000065017 00000 n 0000000016 00000 n Data on the presence of the metabolic syndrome, based on Inter- Carotenoids are a large group of natural pigments, ranging from red, to orange, to yellow colors. startxref These pigments produce the bright yellow, red, and orange colors in plants, vegetables, and fruits. Several components of the metabolic syndrome, particularly diabetes and CVD, are known to be oxidative stress-related conditions and there is research to suggest that antioxidant nutrients may play a protective role in these conditions. Carotenes are carotenoids with molecules that are unoxygenated, such as α-carotene, β-carotene and lycopene. 0000189063 00000 n 0000069502 00000 n 0000022448 00000 n Carotenoids are mainly C40 isoprenoids comprising a large family with more than 700 members that are widely distributed in plants, algae, fungi, and bacteria (Khoo et al., 2011).

For example, provitamin A carotenoids (α- and β-carotene) are the precursors of vitamin A, which plays a role in the prevention of blindness, xerophthalmia, and premature death.9,10 The pigments regulate the flow of energy in the photosynthetic system by either absorbing light energy for photosynthesis, or conferring photoprotection by removing excess energy to minimize damage to plant cells or membranes.

Plastids are the organelles for carotenoid biosynthesis and storage in plant cells. Carotenoids are mostly C 40 terpenoids, a class of hydrocarbons that participate in various biological processes in plants, such as photosynthesis, photomorphogenesis, photoprotection, and development. 0000009137 00000 n Carotenoids exhibit diverse roles during the plant life cycle, are essential components of the photosynthetic apparatus, color agents, and precursors of hormones and aroma compounds, and are also signaling molecules involved in various developmental and environmental signaling pathways (Nisar et al., 2015; Rodriguez-Concepcion et al., 2018a). Approximately 600 unique carotenoids can be found in plant species, as well as select species of algae and fungi. First, they act as accessory light‐harvesting pigments, effectively extending the range of light absorbed by the photosynthetic apparatus. 0000012269 00000 n 0000004386 00000 n 0000014738 00000 n Many flowers, fruits, and roots owe their vivid orange, yellow, and red hues to carotenoids. The oxidative cleavage of carotenoids, catalyzed by carotenoid cleavage dioxygenases (CCDs), gives rise ... plants, and bacteria. Carotenoids are the category of natural tetraterpenoid compounds that give plants a variety of colors and are crucial for plant growth and fitness, and for human health. h�b```b`�g�``Pncf@ a6v/N��%��6�00�� Carotenoids that contain unsubstituted beta-ionone rings (including beta-carotene, alpha-carotene, beta-cryptoxanthin, and gamma-carotene) have vitamin A activity (meaning that they can be converted to retinol). 0000188578 00000 n 0000013531 00000 n Like antioxidants, carotenoids protect cellular damage in your body, which prevents the onset of premature aging along with chronic diseases. 0000015432 00000 n 0000007599 00000 n In plants, carotenoids can occur in roots, stems, leaves, flowers, and fruits. Carotenoids are plant-pigments which you can distinguish by their yellow, orange, and red color. Furthermore, some carotenoids are important nutrients and others exhibit protective effects against several diseases. Xanthophylls are carotenoids with molecules containing oxygen, such as lutein and zeaxanthin. %%EOF 0000221853 00000 n 0000144691 00000 n 0000003656 00000 n Photosynthesis and photoprotection in plants Carotenoids are essential for energy capture from the solar emission spectrum.
