We did not detect any change in DNA organization as a function of temperature between 20 and 40 \u00b0C. The presence of spermine (4+) induces a significant enlargement of the typical size of the hexagonal domains in all phages. We interpret these changes as a reorganization of DNA by movements of defects in the structure, triggered by a partial screening of repulsive interactions.<br><br><a href=\"https:\/\/pubs.acs.org\/doi\/10.1021\/acs.jpcb.6b01783\">J.
