A stunning variety of “hypermodified” blue fluorescent chlorophyll catabolites accumulates in senescent banana leaves, as reported by B. Kräutler et al. in the Full Paper on page 12294 ff. The cover shows a vertical cut through a yellow leaf, as seen by fluorescence microscopy, superimposed with the structures of chlorophyll a and of a major fluorescent catabolite. Colored halos highlight the transformation of red fluorescing chlorophylls to the blue fluorescing breakdown products.
