NDCC Formation Is Inhibited by CO.
Detached wild-type leaves were incubated in the dark for 5 d in glass containers containing 0, 50, and 100% (v/v) CO mixed with ambient air. Colorless catabolites were analyzed by HPLC. HPLC traces at A254 are shown. Pie graphs depict the relative amounts of NDCCS and NCCs. In 100% CO atmosphere, chlorophyll degradation was inhibited and no colorless catabolites were detected.
