Photosystem II light-harvesting complexes were isolated from a number of ulvophycean algae. Some of these lightharvesting complexes displayed unusual features, most notably a high apparent molecular weight (ca. 58,000) when isolated by lithium dodecyl sulfate polyacrylamide gel electrophoresis. Other ulvophycean light-harvesting complexes had a low-molecular weight (ca. 30,000). The distribution of the high-molecular weight complex was limited to certain members of the Caulerpales and Blastophysa rhizopus (Siphonocladales). Within the Caulerpales, there were also spectral differences between the high-molecular weight and low-molecular weight lightharvesting complex types. The differences in light-harvesting complexes in the Ulvophyceae suggest that there are two lines of evolution in the Caulerpales and that Blastophysa may be an intermediate between the Siphonocladales and the Caulerpales.
