However, analyses in which synteny and phylogenetic information were also considered suggest that codon bias and G+C content are poor indicators of HGT [ 45 ] . A role for 'amelioration', whereby structural characteristics of the foreign gene are eventually homogenized to resemble those of the recipient species, has been assumed, but the rate was postulated to be the same as the rate of random, forward mutation [ 42 ] . In addition to alterations in codon usage (as reflected in G+C content), for a bacterial gene to function efficiently in a nematode presumably requires acquisition of regulatory elements (including a promoter) and structural elements (including a poly(A) tail and, optionally, a trans -spliced leader).
Consequently, one cannot be assured that any gene or set of genes that aid in the parasitic lifestyle in one nematode species will also exist in another.
A similarity to a bacterial protein sequence is the simplest criterion for considering a nematode protein, and thus the gene that encodes it, as a possible HGT candidate.
The proof of principle behind this dual scheme was demonstrated by the identification of several miRNAs via a structural analysis of genomic sequence conserved over 50 million years of nematode evolution [ 12 ] . Indeed, the great majority of C. elegans miRNAs identified through the direct cloning approach are conserved in the genome of C. briggsae , with conservation typically extending across the length of the predicted miRNA precursor.
Proteins determined to be rate constant at different significance levels were concatenated and analyzed in MEGA2 [ 29 ] . Nematode position and evolutionary distance were determined for each concatenation.
