Identification of two terpenoids that accumulate in Chinese water chestnut in response to fresh‐cut processing

Food Science &Nutrition, Volume 11, Issue 9, Page 5166-5173, September 2023., 2023
6ß‐Hydroxystigmast‐4‐en‐3‐one and blumenol A were isolated and identified from CWC for the first time. Fresh‐cut processing induced the biosynthesis of these two compounds in CWC during the late stage of storage. Expression of structural genes involved in terpenoid backbone biosynthesis and carotenoid precursor biosynthesis of CWC was induced by ...

Enhancement of violaxanthin accumulation in Nannochloropsis oceanica by overexpressing a carotenoid isomerase gene from Phaeodactylum tricornutum

Frontiers in Microbiology, 2022
Nannochloropsis has been considered as a promising feedstock for the industrial production of violaxanthin. However, a rational breeding strategy for the enhancement of violaxanthin content in this microalga is still vacant, thereby limiting its ...

Molecular evolution and diversification of phytoene synthase (PSY) gene family

Genetics and Molecular Biology, 2022
Phytoene synthase (PSY) is a crucial enzyme required for carotenoid biosynthesis, encoded by a gene family conserved in carotenoid-producing organisms. This gene family is diversified in angiosperms through distinct duplication events.

Genetic basis of microbial carotenogenesis

International Microbiology, 2003
The synthesis of carotenoids begins with the formation of a phytoene from geranylgeranyl pyrophosphate, a well conserved step in all carotenogenic organisms and catalyzed by a phytoene synthase, an enzyme encoded by the crtB ( spy) genes. The next step is the dehydrogenation of the phytoene, which is carried out by phytoene dehydrogenase.

Sterol Regulatory Element-Binding Protein (Sre1) Promotes the Synthesis of Carotenoids and Sterols in Xanthophyllomyces dendrorhous

Frontiers in Microbiology, 2019
Xanthophyllomyces dendrorhous is a basidiomycete yeast that synthesizes carotenoids, mainly astaxanthin, which are of great commercial interest. Currently, there are many unknown aspects related to regulatory mechanisms on the synthesis of carotenoids in

Structural and functional features of phytoene synthase isoforms PSY1 and PSY2 in pepper Capsicum annuum L. cultivars

Вавиловский журнал генетики и селекции, 2020
The fruits of various pepper cultivars are characterized by a different colour, which is determined by the pigment ratio; carotenoids dominate in ripe fruits, while chlorophylls, in immature fruits.

Brazilian Biomes as Promising Resources of Rhodotorula Yeasts for the Biotechnological Production of Carotenoids. [PDF]

Chem Biodivers
ABSTRACT Yeasts belonging to the genus Rhodotorula are capable of synthesizing carotenoids, such as β‐carotene, γ‐carotene, torulene, torularodine, and astaxanthin. These carotenoids have been shown to offer health benefits to humans, such as immune system strengthening and a reduced risk of chronic degenerative diseases.
