  • a UD, undetermined due to a contig break in the 5′-conserved segment (CS) or 3′-CS.

  • b Ninety-seven base pairs of the 5′ side of 3′-CS was absent.

  • c In722 and In1321 have a different aacA4 allele (aacA4′-3 and aacA4′-36, respectively).

  • d IRt, inverted repeat of Tn402-like transposon.
