Phytoene desaturase is localized exclusively in the chloroplast and up-regulated at the mRNA level during accumulation of secondary carotenoids in Haematococcus pluvialis (Volvocales, chlorophyceae).

Journal article

The unicellular green alga Haematococcus pluvialis Flotow is known for its massive accumulation of ketocarotenoids under various stress conditions. Therefore, this microalga is one of the favored organisms for biotechnological production of these antioxidative compounds. Astaxanthin makes up the main part of the secondary carotenoids and is accumulated mostly in an esterified form in extraplastidic lipid vesicles. We have studied phytoene desaturase, an early enzyme of the carotenoid biosynth...
