Carotenogenesis diversification in phylogenetic lineages of Rhodophyta

Journal of Phycology, 2016
Carotenoid composition is very diverse in Rhodophyta. In this study, we investigated whether this variation is related to the phylogeny of this group. Rhodophyta consists of seven classes, and they can be divided into two groups on the basis of their morphology.

Trisporoids and carotenogenesis in Blakeslea trispora

Microbiology, 2014
The recent data on the pathways of carotenoid biosynthesis, which resulted in revision of the earlier concepts, are analyzed. Trisporoid diversity and their role in the sexual process of mucoraceous fungi, resulting in formation of sexual cells (zygospores) are discussed.

Protease and carotenogenesis in Blakeslea trispora

Phytochemistry, 1981
Abstract Carotene production by single and mated Blakeslea trispora has been studied. On mating and on the addition of trisporic acid to minus cultures there was an increase in the membrane bound neutral protease (MW 126 000) activity. The protease probably acts by inactivating the inhibitory protein of carotene biosynthesis resulting in increased ...

Carotenogenesis and Resistance of Micrococcus pyogenes to Tetracyclines

Science, 1959
Although reddish-yellow pigments, mainly δ-carotene and rubixanthine, were present in the original strain of Micrococcus pyogenes var. aureus , mutants highly resistant to tetracyclines were observed to become colorless. All strains lack lipoxidase activity.

End-product regulation of carotenogenesis in Phycomyces

Archives of Microbiology, 1988
Wild-type Phycomyces blakesleeanus synthesizes the yellow pigment, beta-carotene. Colour mutants exhibit various alterations in the biosynthesis of beta-carotene or in its regulation. The presence of certain chemicals in the medium stimulates carotenogenesis in the wild type. We attribute different mechanisms of action to agents which stimulate or fail

Carotenogenesis in Haematococcus pluvialis

Nature, 1955
IN a recent communication1, Goodwin and Jamikorn state that light is necessary for the synthesis of astaxanthin, the carotenoid responsible for the red colour in the alga Haematococcus pluvialis. It is not clear whether this conclusion is reached as a result of their own experience or whether they are referring to earlier information2.

Fluence response relationship of carotenogenesis inNeurospora crassa

Planta, 1980
The fluence response of the blue light induced carotenoid synthesis inNeurospora is biphasic. Using fluence rates between 0.3 and 40 Wm(-2), increasing illumination times beyond 16 min (at 20°C) result in a second rise of the amount of carotenoids synthesized in the subsequent dark period. On altering the temperature, the transition point to the second

Chemical regulators of carotenogenesis by Blakeslea trispora

Phytochemistry, 1980
Abstract The activation of the carotene biosynthetic pathway in Blakeslea trispora was found to occur by trisporic acid and many other compounds such as abscisic acid, β-ionone, α-ionone and vitamin A which share significant structural similarity with trisporic acid.

Studies on carotenogenesis in Blakeslea trispora—I.

Phytochemistry, 1967
Abstract Mated strains of Blakeslea trispora synthesized under our cultural conditions about 850 μg/g dry wt. of carotenes of which about one third is β-carotene, about one third is phytoene, about one sixth γ-carotene and the remainder consists of small amounts of phytofluene, ζ-carotene, lycopene with traces of β-zeacarotene and neurosporene ...
