Abstract In the marine green alga Ulva mutabilis Føyn, large daily fluctuations in respiratory and photosynthetic rates are found after the induction of synchronous formation of gametes and zoospores. A sharp reduction in photosynthetic capacity preceeds the zooid-forming cell divisions. During the same period, samples for polyacrylamide electrophoresis show an initial increase followed by a decrease in the amount of ribulose-1,5-bisphosphate carboxylase. Some other transient protein changes were also noted. A new protein band with MW 51,400 appears in the 48-h sample and becomes a prominent constituent of gametes and zoospores; it may represent tubulin.
