Genetic control of phytoene dehydrogenation in phycomyces

Strains of Phycomyces blakesleeanus carrying mutations in gene carB accumulate large amounts of phytoene. A leaky carB mutant, isolated from a red, lycopene-producing strain, accumulates decreasing amounts of phytoene, phytofluene, ζ-carotene, neurosporene, and lycopene. This indicates that the prod...

Summary:Strains of Phycomyces blakesleeanus carrying mutations in gene carB accumulate large amounts of phytoene. A leaky carB mutant, isolated from a red, lycopene-producing strain, accumulates decreasing amounts of phytoene, phytofluene, ζ-carotene, neurosporene, and lycopene. This indicates that the product of gene carB carries out the four successive dehydrogenations needed to convert phytoene to lycopene.
