A review of life history pathways in Bryopsis

Marina Morabito, Gaetano Gargiulo, Giusi Genovese

Abstract


The genus Bryopsis comprises siphonous green algae widely distributed from tropical to polar seas. Despite the early reports on the simplicity of its life history, subsequent culture observations showed variety of life history patterns, even within a single species. Karyological data and reports on DNA quantification led to somewhat contradictory conclusions about the ploidy level of the two life history phases and about the moment of meiosis. Long term observations on Mediterranean species highlighted new alternatives in recycling of the two morphological phases. Looking at all published experimental data, we summarize all life history pathways of Bryopsis species.
