It is shown that uncertainties in the guide tree used by progressive alignment methods are a major source of alignment uncertainty, and a novel method for quantifying the robustness of each alignment column to guide tree uncertainty is developed, based on the widely used bootstrap method for perturbing the phylogenetic tree.

It is shown that when branch lengths are unknown, it is better first to estimate branch lengths and then to estimate site-specific rates, and that a Bayesian approach is superior to maximum-likelihood under a wide range of conditions.
Alu-containing exons are alternatively spliced.
Results indicate that internal exons that contain an Alu sequence are predominantly, if not exclusively, alternatively spliced, and evolutionary events that cause a constitutive insertion of an AlU sequence into an mRNA are deleterious and selected against.
Functional and Evolutionary Insights from the Genomes of Three Parasitoid Nasonia Species

Key findings include the identification of a functional DNA methylation tool kit; hymenopteran-specific genes including diverse venoms; lateral gene transfers among Pox viruses, Wolbachia, and Nasonia; and the rapid evolution of genes involved in nuclear-mitochondrial interactions that are implicated in speciation.
A fast algorithm for joint reconstruction of ancestral amino acid sequences.
A dynamic programming algorithm for maximum-likelihood reconstruction of the set of all ancestral amino acid sequences in a phylogenetic tree that scales linearly with the number of sequences and is applicable to practically any number of taxa.
ConSurf: an algorithmic tool for the identification of functional regions in proteins by surface mapping of phylogenetic information.

- BiologyJournal of Molecular Biology
- 16 March 2001
A novel methodology based on evolutionary relations among proteins as revealed by inferred phylogenetic trees is presented, and its capabilities for mapping binding sites in SH2 and PTB signaling domains are demonstrated.
