Effect of wild type Pantoea sp. YR343 on Populus deltoides WV94 growth.

Sample treatment	Leaf number	Total leaf area (cm2)	Stem height (cm)	Root area (cm2)
Uninoculated	2.67 ± 1.15	12.45 ± 12.45	2.99 ± 1.39	14.35 ± 7.58
Soila	2.67 ± 0.58	13.30 ± 2.69	1.58 ± 0.44	10.31 ± 3.84
Leafb	3.33 ± 1.53	16.98 ± 3.44	2.04 ± 0.32	10.44 ± 1.51

Values represent the average differences in samples before and after treatment. ^aPopulus plants were inoculated by mixing bacterial culture with the soil prior to addition of the plant. ^bPopulus plants were inoculated by swabbing bacterial culture on the leaves of individual plants and then planting into sterile soil.
