  abstract = {{M}eloidogyne graminicola, also known as the rice root-knot nematode, is one of the most damaging plant-parasitic nematode, especially on rice. {T}his obligate soilbome parasite induces the formation of galls that disturb the root morphology and physiology. {I}ts impact on the root microbiome is still not well described. {H}ere, we conducted a survey in {N}orthern {V}ietnam where we collected infected (with galls) and non-infected root tips from the same plants in three naturally infested fields. {U}sing a metabarcoding approach, we discovered that {M}. graminicola infection caused modifications of the root bacterial community composition and network structure. {I}nterestingly, we observed in infected roots a higher diversity and species richness (+24% observed {ESV}s) as well as a denser and more complex co-occurrence network (+44% nodes and +136% links). {W}e identified enriched taxa that include several hubs, which could serve as potential indicators or biocontrol agents of the nematode infection. {M}oreover, the community of infected roots is more specific suggesting changes in the functional capabilities to survive in the gall environment. {W}e thus describe the signature of the gall microbiome (the 'gallobiome, with shifting abundances and enrichments that lead to a strong restructuration of the root microbiome.},
