Often, only the region of the plots above a certain threshold (e.g., average identity across the alignment) is shown in figures, highlighting the conserved peaks. This is for ease of reference, and also because the depth of the troughs are determined mainly by the number of indels, rather than the absolute level of variation per... 

The location of the indel around position 254 would be haid to find based on sequence information alone. Visual inspection of the structure around this position made clear, however, that the threonine at position 254 is sitting in a beta-bulge. This residue can be deleted with only minimal disturbance of the local environment in the structure. Additional facts in favor of this solution for the local sequence-alignment problem are that the glycine at position 256 ends up favorably in a (3-tum and that all residues seem to fit well in their three-dimensional environment. 

Insertions and deletions are normally only tolerated in regions not associated with the biuied core of the protein. Thus, in a good multiple alignment, the location of indels suggests surface loops rather than a-helices or )8-strands. 

Start from the known sequences and align the sequences of the target and the protein or proteins of known structure. Often the InDels (insertions and deletions) between the related structures occur in the loop regions between a-helices and p-strands. 

When verifying alterations in sequences from different genomes, the natural way to detect SNPs/InDels is to do this in two separate steps (a) to align the DNA sequences of interest and (b) to verify possible differences between them. A new bioinformatics tool can be developed for executing both steps in order to make this detection process more accurate and, mainly, faster. 

Once the main clades within the Brachytheciaceae had become more or less stabilized, our main goal was to elucidate the position of taxa not included or not well represented in the previous analyses, and also to find additional arguments for generic and subfamilial placement of some particular taxa. Three methods are involved here (1) evaluation of the molecular synapomorphies in POY alignment, i.e., characteristic indel events and substitutions (2) analysis of the secondary structure of the tmL intron and (3) phylogenetic analysis of a reduced dataset from previous analyses, with some additional taxa. 

FIGURE 6.3 The secondary structure of the tmL intron of Brachythecium cirmsum and secondary structures of P8 regions of Oxyrrhynchium Mans and Donrichardsia macroneuron. Numbers indicate positions in POY alignment where substitutions/indels occur (see supplemental CD). 

Common substitutions/indels in the intron were mapped on the Rigodiadelphus robustus structure (Figure 9.5) based on the alignment for the dataset 1 (see Appendix 9.2 on the supplemental CD). Special attention was paid to substitutions in conservative S, P-Q, and R parts of the intron. Rigodiadelphus robustus was selected for this procedure because its intron, as far as was possible to evaluate by eye from the alignment, has the minimum of peculiar substitutions observed in other species of Leskeaceae involved in the analysis.
