Abstract excerpt
An unusually high divergence was observed in the ribosomal RNA genes of a free-living population of foraminifera belonging to the genus Ammonia. The sequences of a large-subunit (LSU) rDNA expansion segment D1 and flanking regions were obtained from 20 specimens named Ammonia sp. 1 and Ammonia sp. 2. The sequence divergence between the two species averages 14%. Within each species it ranges from 0.2% to 7.1% in...
