Floral fluorescence effect
Article Abstract:
An internal light-filtering effect in the flowers of Mirabilis jalapa, in which the visible fluorescence emitted by one pigment, a yellow betaxanthin, is absorbed by another, a violet betacyanin to create a contrasting fluorescent pattern on the flower's petals is described. Measurement of the fluorescence-emission spectrum of dopaxanthin and the absorbance spectrum of betanin indicates that the light emitted by the fluorophore is strongly reabsorbed.

Atto labels and their conjugates - Versatile, bright and stable tools for imaging
Article Abstract:
Atto dyes provide the brightest fluorescence with narrow fluorescence emission spectra. Atto 488, a superior alternative to the widely used fluorescein, provides tremendously improved photostability and more intense fluorescence.
