Chlorophyll is broken down in leaves during Fall to colorless tetrapyrroles, so‐called phyllobilanes, which are degraded further in leaves into yellow oxidation products. The hypothetical “missing link” between the colorless and the yellow catabolites has now appeared on the scene, as described in the Full Paper by B. Kräutler et al. on page 136 ff.
In senescent leaves, chlorophyll typically is broken down to colorless and essentially photo‐inactive phyllobilanes, which are linear tetrapyrroles classified as “nonfluorescent” chlorophyll catabolites (NCCs) and dioxobilane‐type NCCs (DNCCs). In homogenates of senescent leaves of the tropical evergreen Spathiphyllum wallisii, when left at room temperature and extracted with methanol, the major endogenous,...
