Abstract: | Background While Expressed Sequence Tags (ESTs) have proven a viable and efficient way to sample genomes, particularly those for which
whole-genome sequencing is impractical, phylogenetic analysis using ESTs remains difficult. Sequencing errors and orthology
determination are the major problems when using ESTs as a source of characters for systematics. Here we develop methods to
incorporate EST sequence information in a simultaneous analysis framework to address controversial phylogenetic questions
regarding the relationships among the major groups of seed plants. We use an automated, phylogenetically derived approach
to orthology determination called OrthologID generate a phylogeny based on 43 process partitions, many of which are derived
from ESTs, and examine several measures of support to assess the utility of EST data for phylogenies. |
