Tn5 insertion in S.meliloti
WGS analysis of S.meliloti in nodules and free living. The nifH nodules independent samples are H1, H3, H4, H5, H6, and H7. (H2 is missing). The free-living nifH bacteria are denominated as NifH917, NifH921, and NifH925.  The free-living WT bacteria are named WT917, WT921, and WT925.  The nodules samples are biological replicates, and the free-living bacteria samples are collected at different generations (NifH917: first-generation; NifH921: third generation, and NifH925: fifth generation).
