| subset partitioning of the ribosomal dna small subunit and its effects on the phylogeny of the anopheles punctulatus group. | a phylogenetic study, based on maximum parsimony, of ten species in the anopheles punctulatus group of malaria vectors from the south-west pacific was performed using structural and similarity-based dna sequence alignments of the nuclear small ribosomal subunit (ssu = 18s). the structural alignment proved to be more informative than a computer generated similarity-based alignment. analyses involving the full structural sequence alignment (2169 bp) and the helical regions (1547 bp) resolved a sin ... | 2000 | 11029670 |
