Green macroalgae

More recent studies have documented the occurrence of a specific U VB-absorbing compound with an absorption maximum at 294 nm in the green macroalga Ulva pertusa (Han and Han 2005). UVB-radiation strongly induced this compound and its accumulation resulted in a higher photosynthetic performance under U V exposure,...
