Metabolic phenotype of pahx Arabidopsis mutants plants during growth under extended dark conditions. Phytanoyl-CoA (A), 2-hydroxyglutarate (B), and isovaleryl-CoA (C) profiles in pahx Arabidopsis mutants under extended dark treatment. Samples were taken from the ninth or 10th leaves of 4-week-old, short-day-grown, Arabidopsis plants after further growth for 0, 3, 7, 10, and 15 d in extended darkness. Values are means ± se of six independent samplings; an asterisk indicates values that were determined by the Student’s t test to be significantly different (P < 0.05) from the wild type.
