- The circle below represents the chromosome of S. elongatus PCC 7942.
- Green arched rectangles on the circle indicate the map positions, and lengths to scale, of cosmids that have undergone saturation mutagenesis.
- An asterisk indicates the subset of cosmids that was mutagenized by Tn5 rather than Mu.
- Where cosmids appear to abut, they overlap, and the cosmid names are indicated as a group.
- Red arcs represent the positions of JGI 8-kb plasmid sets that are being mutagenized to fill the gaps left after cosmid mutagenesis.
- The position and extent of a large inversion in PCC 7942 genome relative to that of PCC 6301 is indicated by a double-headed arrow.
- There are two endogenous plasmids in PCC 7942: pANL [AF441790] and pANS [S89470]. The plasmid pANS (also as pUH24) was sequenced by Van der Plas J, Oosterhoff-Teertstra R, Borrias M and Weisbeek P (1992).
