Carotenoids in Algae: Distributions, Biosyntheses and Functions

open access: yesMarine Drugs, 2011
For photosynthesis, phototrophic organisms necessarily synthesize not only chlorophylls but also carotenoids. Many kinds of carotenoids are found in algae and, recently, taxonomic studies of algae have been developed.

The oleaginous astaxanthin-producing alga Chromochloris zofingiensis: potential from production to an emerging model for studying lipid metabolism and carotenogenesis

open access: yesBiotechnology for Biofuels, 2021
The algal lipids-based biodiesel, albeit having advantages over plant oils, still remains high in the production cost. Co-production of value-added products with lipids has the potential to add benefits and is thus believed to be a promising strategy to ...

Largely different carotenogenesis in two pummelo fruits with different flesh colors.

open access: yesPLoS ONE, 2018
Carotenoids in citrus fruits have health benefits and make the fruits visually attractive. Red-fleshed 'Chuhong' ('CH') and pale green-fleshed 'Feicui' ('FC') pummelo (Citrus maxima (Burm) Merr.) fruits are interesting materials for studying the ...

Characterization of Dunaliella salina strains by flow cytometry: a new approach to select carotenoid hyperproducing strains [PDF]

open access: yes, 2008
In the present work the characterization of different strains of Dunaliella salina from established cell culture collections and various isolates from solar saltworks located in the Canary Island, as well as one mutant, was carried out in order to assess

Synthesis, Regulation and Degradation of Carotenoids Under Low Level UV-B Radiation in the Filamentous Cyanobacterium Chlorogloeopsis fritschii PCC 6912

open access: yesFrontiers in Microbiology, 2020
Carotenoids in cyanobacteria play an important role in protecting against and in repairing damage against low level UV-B radiation. Here we use transcriptomics and metabolomic HPLC pigment analysis to compare carotenoid pathway regulation in the ...

Integrated Transcriptomic and Metabolomic analysis reveals a transcriptional regulation network for the biosynthesis of carotenoids and flavonoids in ‘Cara cara’ navel Orange

open access: yesBMC Plant Biology, 2021
Background Carotenoids and flavonoids are important secondary metabolites in plants, which exert multiple bioactivities and benefits to human health. Although the genes that encode carotenogenesis and flavonoid biosynthetic enzymes are well characterized,

Differential Regulation of Phytoene Synthase PSY1 During Fruit Carotenogenesis in Cultivated and Wild Tomato Species (Solanum section Lycopersicon)

open access: yesPlants, 2020
In plants, carotenoids define fruit pigmentation and are involved in the processes of photo-oxidative stress defense and phytohormone production; a key enzyme responsible for carotene synthesis in fruit is phytoene synthase 1 (PSY1).

The combined effects of Golden2‐like 2 and Pseudo‐Response Regulator 2 control the fruit pigmentation in pepper

open access: yesThe Plant Journal, Volume 125, Issue 5, March 2026.
SUMMARY Fruit pigmentation mainly controlled by chlorophyll, carotenoids, and flavonoids is an important phenomenon for fortifying the nutritional and esthetic value of humans. Our previous study identified Pseudo‐Response Regulator 2 (PRR2) as a regulator of fruit pigmentation through its association with the c1 locus.

Light quality rather than oxidative stress impacts fucoxanthin content in Coscinodiscus radiatus and Cylindrotheca sp.

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1143-1163, December 2025.
ABSTRACT We investigated the impact of light intensity, light quality, and temperature on growth rate, fucoxanthin (Fx), chlorophyll a and c (Chl a and c), and total carotenoid (Car) contents of the two marine diatoms Coscinodiscus radiatus and Cylindrotheca sp. Additionally, we analysed antioxidant enzyme activities and lipid peroxidation to determine
