Fig. 3. Relative abundance, phylogeny and plant growth promotion of the Jizan strains isolated from Indigofera argentea.

Fig. 3

a Jizan strains belonged to highly abundant OTUs in either the Rhizo or EC of indigofera. The x axis shows the relative abundance of the best matching OTU for each Jizan strain. b Maximum likelihood tree based on the AMPHORA gene alignments of 15 Jizan strains - colored in red. The black filled circles on the outer perimeter indicate desert-associated strains. Representative strains for each genus were also included. The distance scale indicates the number of differences between sequences. c, d Quantitative analysis of shoot fresh weight of seven-week-old indigofera (c) and three-week-old tomato (d) plants grown under sterile conditions with or without the Jizan SynCom. In both cases, the Jizan Syncom led to a better plant yield compared to the control. Asterisks indicate statistical significance (p < 0.05) as per Dunnett’s post-hoc test.
