Rose, et al., (1982) previously described a RFLD (restriction fragment length difference) that mapped to linkage group I, and that resulted from the insertion of a transposon into the BO strain. Genomic blot hybridization and restriction mapping demonstrated that our transposon was (almost) identical to the Tc1 characterized by Emmons, et al., (1982) with the exception that ours contained a HindIII site which was absent in Tc1 . We have now sequenced a portion of the Tc1(Hin), and find 2 nucleotide changes in the 200 or so, base pairs that we have examined. One of these changes generates a HindIII site at position 1310 in the published Tc1 sequence ( Rosenzweig, et al., 1983). Tc1(Hin) is inserted (not surprisingly) into an A/T rich region of linkage group I. We are hoping to use the Hind III restriction site as a genetic marker to follow mobility of this transposon.
