Nodule occupancy of Glycine soja accessions CH3 and CH4 inoculated with S. fredii HH103 and its ttsI and rhcJ mutants.

G. soja accession	Pairs of inoculants	TNN	% of nodule occupancy by mutant SVQ533 or SVQ288
CH3	S. fredii HH103 RifR/SVQ533	127	10.2
	S. fredii HH103 StrR/SVQ288	161	15.5
CH4	S. fredii HH103 RifR/SVQ533	156	10.9
	S. fredii HH103 StrR/SVQ288	207	10.4

TNN, total number of nodules tested in two independent experiments.

In each experiment, 5 jars were inoculated per pair of competitors. Each jar contained 2 plants.

YMA supplemented with spectinomycin or neomycin (50 μg/ml) were used to detect the presence of SVQ533 or SVQ288, respectively.
