Colour and UV-B-absorbing compound localisation differences between exposed (red) and shaded (green) Antarctic C. purpureus. a Photographs of red and green gametophyte photosynthetic tips. Light microscopy images of b red and c green leaves. Confocal microscopy fluorescence images of d red and e green leaves stained with Naturstoff reagent A to visualise the location of UV-B-absorbing compounds. Yellow/orange fluorescence indicates the presence of phenolic compounds. Scale bars in b–e are 25 μm
