Analysis of al-2 mutations in Neurospora.
The orange pigmentation of the fungus Neurospora crassa is due to the accumulation of the xanthophyll neurosporaxanthin and precursor carotenoids.

The yl Gene of Maize Codes for Phytoene Synthase [PDF]
Abstract The cloned yl locus of maize was sequenced and found to encode phytoene synthase. Different “wild-type” alleles of the locus were found to differ by the insertion of transposable elements in their promoter and polyA addition regions, and by the length of a CCA tandem repeat series, without any obvious effect on function of the ...

Engineering Haloferax mediterranei as an Efficient Platform for High Level Production of Lycopene
Lycopene attracts increasing interests in the pharmaceutical, food, and cosmetic industries due to its anti-oxidative and anti-cancer properties. Compared with other lycopene production methods, such as chemical synthesis or direct extraction from plants,

Genetic stability developed for β-carotene synthesis in BR29 rice line using dihaploid homozygosity. [PDF]
Obtaining transgenic crop lines with stable levels of carotenoids is highly desirable. We addressed this issue by employing the anther culture technique to develop dihaploid lines containing genes involved in β-carotene metabolism.

Engineering of Yarrowia lipolytica for production of astaxanthin
Astaxanthin is a red-colored carotenoid, used as food and feed additive. Astaxanthin is mainly produced by chemical synthesis, however, the process is expensive and synthetic astaxanthin is not approved for human consumption. In this study, we engineered

Unraveling transcriptomics of sorghum grain carotenoids: a step forward for biofortification
Background Sorghum (Sorghum bicolor [L.] Moench) is a promising target for pro-vitamin A biofortification as it is a global staple crop, particularly in regions where vitamin A deficiency is prevalent.

A genetic screen to identify mutants that can increase flux in the isoprenoid pathway of yeast has been lacking. We describe a carotenoid-based visual screen built with the core carotenogenic enzymes from the red yeast Rhodosporidium toruloides.

Background Plants have remarkable diversity in petal colour through the biosynthesis and accumulation of various pigments. To better understand the mechanisms regulating petal pigmentation in Lonicera japonica, we used multiple approaches to investigate ...

Carotenoids are the main pigments in watermelon (Citrullus lanatus L.) fruit and contribute to its aesthetic and nutritional value. Phytoene synthase (PSY) is reported to be the first rate-limiting enzyme in carotenogenesis and controls the carotenoid ...

Seed‐specific overexpression of phytoene synthase: increase in carotenoids and other metabolic effects [PDF]
SummaryA bacterial phytoene synthase (crtB) gene was overexpressed in a seed‐specific manner and the protein product targeted to the plastid in Brassica napus (canola). The resultant embryos from these transgenic plants were visibly orange and the mature seed contained up to a 50‐fold increase in carotenoids. The predominant carotenoids accumulating in
