Polyphyletic analyses of the presence of photoprotective compounds and zeaxanthin epoxidase sequences across a wide representation of the plant kingdom reveals no correlation between the presence of lutein-epoxide and recurrent mutations in sequences, including the duplications. There is an evolutionary trend to increase the content of alpha-tocopherol and to decrease the total amount of violaxanthin-cycle pigments.
