Abstract: Photosynthesis rate and carbonic anhydrase (CA) activity have been studied in the green seaweed Ulva rigida C. Agardh (Chlorophyta) grown in seawater (SW) and SW supplemented with 40 mu M NH4Cl (N-SW). Higher growth and maximal O-2 evolution rates were observed in N-SW- than in SW-grown seaweeds. Western blot analysis of the total homogenates probed with antibodies raised against small subunits of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) showed crossreaction with a 15 kdalton polypeptide in both SW- and N-SW-grown plants, although the band was more intense in N-SW-grown plants. Carbonic anhydrase activities in the total homogenate and in the soluble protein fraction were higher in N-SW-grown plants. Although the pellets from both plants showed a considerable CA activity, the activity of CA in the thylakoid membranes was undetectable. The low nitrogen concentration is a major environmental factor that affects the level of RuBisCO and CA, and therefore CO2 assimilation in U. rigida.
