Carbonic anhydrase levels and internal lacunar CO2 concentrations in aquatic macrophytes

Carbonic anhydrase levels were examined in a variety of aquatic macrophytes from different habitats. Carbonic anhydrase levels increased across the habitat gradient, from low activity in submersed aquatic macrophytes, intermediate in floating-leaved and free-floating plants to high activity in emerg...

Description
Summary:Carbonic anhydrase levels were examined in a variety of aquatic macrophytes from different habitats. Carbonic anhydrase levels increased across the habitat gradient, from low activity in submersed aquatic macrophytes, intermediate in floating-leaved and free-floating plants to high activity in emergent macrophytes. Internal CO2 concentrations ranged from low to high in submersed macrophytes, but were low in floating-leaved and emergent macrophytes. No correlation was found between internal lacunar CO2 concentrations and carbonic anhydrase activities.
