Figure 1From: Large-scale genetic variation of the symbiosis-required megaplasmid pSymA revealed by comparative genomic analysis of Sinorhizobium meliloti natural strainsNumber and location of variable ORFs on the three replicons. Genes considered were significantly different in hybridisation from strain Rm1021 at p < 0.001. A), Genes with Log2-ratio > 0; B) genes with Log2-ratio < 0. Asterisks over the columns indicate significant enrichment at p < 0.0001.Back to article page
