Figure 8. QR tracking under feeding and starvation regimes.

Labelled polyps were cultured under normal feeding regimes (A and C), or kept under starvation condition (B and D) for the corresponding times. The first feeding started 24 h post treatment, and the following ones carried out every other days as detailed in the Materials and Methods section. The localization of the fluorescence at the subhypostomal region is clearly shown in the longitudinal section representing the inset of picture D. Starvation enhances QR accumulation in the hypostomal region.
