Cuticular wax of dwarf mountain pine enhance photosynthesis by having fluorophores that convert harmful solar UV into blue light that can be utilised for photosynthesis in low-light conditions.

"[T]he P. mugo [Pinus] grown at high elevations in the Alps has a cuticular wax coat that also contains fluorophores, which convert the harmful solar UV into blue light. This additional blue light can be utilised for photosynthesis in low-light conditions, which gives the P. mugo ecological advantage over other Alpine species. The principle of turning useless...radiation into useful energy sets an example for new biological based coatings." (Jacobs 2007:166)
