FIG. 1.
Genomic distribution of SSH-enriched DNA fragments. SSH-enriched DNA sequences from Synechococcus sp. strain WH8103 were mapped on the complete genome of Synechococcus sp. strain WH8102 (outer circle), while SSH-enriched sequences from Synechococcus sp. strain WH7803 were mapped on the complete genome sequence of this strain (inner circle). The origin of both sequences is indicated by an arrow.
