JEK, DS, HHS and CGE carried out molecular genetic and immunohistochemical studies.
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.
In contrast to the ubiquitous DDRP, cellular RDRPs that are involved in PTGS so far have been detected only in eukaryotes [ 1 26 ] . The PTGS phenomenon covers a variety of complementarity-dependent silencing pathways, such as RNA interference (RNAi) in animals and slime mold, co-suppression (silencing of transgene and the corresponding endogenous genes) and virus gene resistance in plants, and quelling in fungi, all of which share a common mechanism of RNA turnover [ 28 37 38 39 40 ] . Essentially, double-stranded (ds) RNA, which is formed in these processes, triggers the activation of a sequence-specific RNA degradation system, which targets homologous RNAs [ 41 42 ] . The dsRNA is broken down by the Dicer enzyme into 21-25 nucleotide (nt) fragments called small interfering RNA or siRNAs [ 43 44 45 ] . The siRNAs subsequently associate with a complex of proteins called RISC and target homologous RNA by serving as guides for multiple rounds of RNA cleavage [ 45 46 ] .
ds cDNA was extracted with an equal volume of phenol:chloroform: isoamyl alcohol (25:24:1), transferred to a Phase Lock Gel™ tube (Eppendorf) and centrifuged at 16,000 g for 5 min.
DS generated the new intron sequences.
