Effect of Arbuscular Mycorrhiza establishment on the genetic structure and functionality of bacterial communities in the rhizosphere of Medicago trun…

Bacterial communities associated with (i) M. Truncatula J5 (Myc+/Nod+) and TRV48 (Myc+/Nod-), and with (ii) M. Truncatula TRV25 (Myc-/Nod-) were compared. The genetic structure of communities was characterized with an A-RISA DNA fingerprint. The genetic structures of communities associated with mycorrhizal and non-mycorrhizal roots were significantly different. Bacteria belonging to the Oxalobacteraceae and Comamonadaceae families were preferentially associated with mycorrhizal roots. The genetic diversity of cultured bacteria belonging to these groups was analysed by BOX-PCR. The diversity of isolates from mycorrhizal and non-mycorrhizal roots was significantly different. The functionality…
