Expression

Organism Comment Expression
Haematococcus lacustris high-light intensity leads to a transient increase in carotenoid hydroxylase mRNA level. Addition of sodium acetate and ferrous sulfate and increasing the light intensity results in a strong increase in steady-state mRNA level of the carotenoid hydroxylase after 8 h with the highest transcript level of carotenoid hydroxylase at 24 to 48 h up
Haematococcus lacustris in the presence of 3-(3,4-dichlorophenyl)-1,1-dimethylurea, the light induction of carotenoid hydroxylase is abolished down
Haematococcus lacustris the addition of compounds inducing reactive oxygen species like methyl viologen does not influence transcript levels of carotenoid hydroxylase. No transcript for carotenoid hydroxylase is detected after growth for 4 days under a dark/light cycle and low-light conditions additional information
