摘要：

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.
