Other claims from this paper (7)
- Observation Three S. meliloti Tn5 mutants with increased symbiotic efficiency were obtained, and their symbiotic phenotypes depend on the host.
- Observation In a two-factor analysis of variance, the genotypic difference between the S. meliloti mutants was most pronounced under salt stress.
- Observation Without salt stress, symbiotic efficiency was determined mostly by the host genotype.
- Observation The T4 mutant carries the Tn5 insertion in the mtaD gene.
- Observation The T795 mutant carries the Tn5 insertion in the thiC gene.
- Observation The M3 mutant carries the Tn5 insertion in a gene encoding a protein of the GntR family of transcription regulators.
- Method / resource The inverted PCR method allowed rapid extraction of DNA fragments flanking the Tn5 transposon, suggesting it can be used to identify new rhizobial genes marked by Tn5.
