摘要: It is at present difficult to accurately position gaps in sequence alignment and determine substructural homology structure when reconstructing phylogenies based on highly divergent sequences. Therefore, we have developed a new strategy for inferring In this strategy, the whole secondary presented as string bracket notation used phylogenetic characters infer relationships. no longer necessary decompose into homologous components. study, reliable relationships of eight species Pectinidae were inferred from alignment, but not even with aid structural information. The results suggest that should be useful Moreover, evolution ITS1 was also investigated. could divided four domains. Compensatory changes found all Structural motifs these domains identified further. These motifs, especially those D2 D3, may important functions maturation rRNAs.
