Yellow leaves of bananas glow blue under UV light. The luminescence is caused by uniquely glycosylated (“hypermodified”) chlorophyll catabolites that accumulate in senescent banana leaves. These findings suggest that (some) chlorophyll catabolites are not mere detoxification products, but are likely to play still unknown physiological roles.
