51	Table S1	For each IS families and groups, defined in the database Isfinder (http://www-is.biotoul.fr/), this table provides the following information: 1) length, 2) existence of Direct Repeats that were generated during transposition and 3) Inverted Repeats of its members, whether 4) cyanobacteria and 5) archaea are proposed in ISfinder to harbor its members, and the number of 6) cyanobacteria and 7) archaea that are predicted by ISA system to contain raIS elements in this family and group. Column 8) Total_Org# equals to (ISA_Cyano# + ISA_Archaea#). Column ReviewArchaea shows whether this IS group was found in archaea in a recent review (Filee J, et al 2007).
