Colorless catabolites of mes16 mutants. A, Colorless catabolites of dark-incubated (10 d) leaves of Col-0 and mes16 mutants were separated by HPLC as described in “Materials and Methods.” A₃₂₀ is shown. For clarity, only a part of the HPLC traces is shown. For identification and peak numbering of FCCs and NCCs, see Table I. B, Relative contents of NCCs and FCCs. Values are means of three replicates. Error bars indicate sd. C, Photographs of dark-incubated (10 d) Col-0 and mes16 leaves under white light and UV light (366 nm). Bar = 1 cm.
