Frequency of EaganstrRand Eagan SNPs in the Rd+EaganstrRand Rd+Eagan transformants. Panel A; Location and frequency of EaganstrR specific SNPs plotted as estimated number of strains (y-axis) against location in RdKW20 genome sequence (x-axis) using SNPSeeker. MAQ was used to identify SNPs in the pooled sequences from 200 transformants. The location of the strR point mutation is indicated. Panel B; A magnified view of one region marked on Panel A showing a putative secondary transformation event. The extent of the chromosomal region involved with this predicted transformation event (13 kbp) is marked. Panel C; A magnified view of the primary transformation event from Panel A with the location of the strR point mutation marked. Panel D; The location and frequency of Eagan-specific SNPs in the genome of pooled Rd+Eagan transformants (200); Eagan unmarked (wild-type) genomic DNA was used as the donor.
