Phytoene desaturase (lycopene-forming) of a bacterial phytoene desaturase into transgenic tomatos increased the lycopene content without the need to alter several of the plants enzymes. This approach was later used in rice to increase its β-carotene content resulting in the Golden Rice project. Phytoene desaturase (lycopene-forming) Phytoene desaturase (lycopene-forming) (CrtI, "four-step phytoene desaturase") (, "15-cis-phytoene:acceptor oxidoreductase (lycopene-forming)") are enzymes found in archaea, bacteria and fungi that are involved in carotenoid biosynthesis. They catalyze the conversion of colorless 15-"cis"-phytoene into a bright red lycopene in a biochemical pathway called the poly-trans pathway. The same process in plants and cyanobacteria utilizes four separate enzymes in
This Is Colour This Is Colour's extensive merchandise included the popular line of 'Stay Rad' t-shirts and vests. This phrase inspired a whole array of rip off's and alternative uses.
