For RT reactions, one microgram of total RNAs was reverse transcribed from random (dN)6 primers in 20 μl of reaction medium containing 1 mM each deoxynucleoside triphosphate, (dN)6 (2 mM), 20 U of RNAsin, 50 mM Tris-HCl, 75 mM KCl, 5 mM MgCl 2 , and 50 U of Moloney murine leukemia virus reverse transcriptase (Applied Biosystem).
The plot of the ratio of synonymous/nonsynonymous substitutions (dS/dN) identified five regions where the synonymous substitution rate exceeds the nonsynonymous substitution rate (dS / dN > 1), suggesting that homology in these areas was driven by the need for AA conservation (Figure 2b).
Visual inspection of the NA alignment of the high homology group revealed that substitutions in the areas where dS exceeded dN tended to involve the second and third bases of the codons, confirming the previous suggestion (data not shown).
Mutations in TMC1 are responsible for the autosomal dominant human hearing disorder DFNA36 and for the recessive deafness DFNB7/11 [ 5 ] ; the corresponding murine gene Tmc1 also causes deafness in the mutant mouse strains Beethoven ( Bth ) and deafness ( dn ) [ 6 ] . Bth / Bth mice display altered potassium currents in early postnatal cochlear hair cells, in particular Ik,n and Ik,f currents appear to be depressed [ 10 ] . This observation led to the hypothesis that Tmc1 may participate directly or indirectly in regulating the permeability of potassium channels [ 10 ] . Because of the high level of conservation of the amino acid sequences among the eight mammalian TMC proteins (Figure 1, Additional file 1), we speculate that other TMC proteins may as well be modifiers of ion channels or transporters.
Likewise, the oriC region in M. paratuberculosis was found to share a high level of nucleotide identity (~98%) with M. avium . Calculation of the rates of total nucleotide diversity (3) and synonymous substitution per synonymous site (ds) and non-synonymous substitution per non-synonymous site (dn) revealed patterns of variation within the range observed from sequence data outside the oriC region.
