Carotenoid biosynthesis in flowering plants.

چکیده

The general scheme of carotenoid biosynthesis has been known for more than three decades. However, molecular description of the pathway in plants began only in the 1990s after the genes for the carotenogenic enzymes were cloned. Recent data on the biochemistry of carotenogenesis and its regulation in vivo present the possibility of genetically manipulating this pathway in crop plants.

Regulation of carotenoid composition and shoot branching in Arabidopsis by a chromatin modifying histone methyltransferase, SDG8.

Carotenoid pigments are critical for plant survival, and carotenoid composition is tuned to the developmental stage, tissue, and to environmental stimuli. We report the cloning of the CAROTENOID CHLOROPLAST REGULATORY1 (CCR1) gene. The ccr1 mutant has increased shoot branching and altered carotenoid composition, namely, reduced lutein in leaves and accumulation of cis-carotenes in dark-grown se...

A Review on Biosynthesis, Health Benefits and Extraction Methods of Fucoxanthin, Particular Marine Carotenoids in Algae

Fucoxanthin, an allenic carotenoid, is abundant in macro and microalgae as a component of the light-harvesting complex for photosynthesis and photo protection. This carotenoid has shown important pharmaceutical bioactivity, exerting antioxidant, anti-cancer, anti-diabetic, anti-obesity, anti-photoaging, anti-angiogenic, and anti-metastatic effects on a variety of biological models. This caroten...

Light-dependent regulation of carotenoid biosynthesis in plants

L. Pizarro, and C. Stange. 2009. Light-dependent regulation of carotenoid biosynthesis in plants. Cien. Inv. Agr. 36(2):143-162. Carotenoids are colored terpenes synthesized in plants, algae and some yeasts and bacteria. In plants and algae, these lipophilic molecules exert functional roles in hormone synthesis, photosynthesis, photomorphogenesis and photoprotection. Additionally, they possess ...

Season-controlled changes in biochemical constituents and oxidase enzyme activities in tomato (Lycopersicon esculentum Mill.).

Season-controlled changes in biochemical constituents viz. carotenoids (carotene and xanthophyll) and pectic substances along with IAA-oxidase and polyphenol oxidase (PPO) enzyme activities were estimated/assayed in leaves of Lycopersicon esculentum Mill. (tomato) in two developmental stages--pre-flowering (35 days after sowing) and post-flowering (75 days after sowing) in three different seaso...

Eubacteria show their true colors: genetics of carotenoid pigment biosynthesis from microbes to plants.

The opportunities to understand eubacterial carotenoid biosynthesis and apply the lessons learned in this field to eukaryotes have improved dramatically in the last several years. On the other hand, many questions remain. Although the pigments illustrated in Fig. 2 represent only a small fraction of the carotenoids found in nature, the characterization of eubacterial genes required for their bi...
