Table 6 SMc00911-disruption strains out-compete S. meliloti 1021 wild type for nodule occupancy

From: A comparative genomics screen identifies a Sinorhizobium meliloti 1021 sodM-like gene strongly expressed within host plant nodules

Inoculum Number of nodules tested* Number of nodules containing no neomycin-resistant bacteria Number of nodules containing only neomycin-resistant bacteria Number of nodules containing a mixture of neomycin-resistant and sensitive bacteria Average percent of neomycin-resistant bacteria in mixed nodules
