Absence of major differences between soluble proteins from haploid gametophytes and diploid sporophytes in the green alga Ulva mutabilis Føyn.

Soluble proteins from haploid gametophytes and diploid sporophytes of the marine green alga Ulva mutabilis Føyn have been reexamined, using polyacrylamide gel electrophoresis and isoelectric focusing. A two-dimensional system resolved about 150 protein spots. In contrast to an earlier report (Hoxmark (1976) Planta 130, 327-332), no major differences could be detected between soluble proteins from the two generation types by any of the methods used.
