Visualizing and assessing phylogenetic congruence of core gene sets: a case study of the gamma-proteobacteria.

abstract：:We report the complete sequence of a paralogous copy of elongation factor-1 alpha (EF-1 alpha) in the honeybee, Apis mellifera (Hymenoptera: Apidae). This copy differs from a previously described copy in the positions of five introns and in 25% of the nucleotide sites in the coding regions. The existence of two paralo...
