e0“In vitro inoculated potato (Solanum tuberosum) nodal explants produced plantlets with significant increases in root number (24-196%), root dry weight (44-201%), haulm dry weight (14-151%), and stem length (26-28%) as compared with noninoculated control plants”
e1“Ps JN persisted through successive generations of in vitro cultured potato plantlets”

Other claims from this paper (16)
- Observation Ps JN was identified as a nonfluorescent Pseudomonas species.
- Observation Ps JN similarity to P. gladioli was 77%.
- Observation Ps JN similarity to P. cichorii was 70%.
- Observation Ps JN similarity to P. viridiflava was 66%.
- Observation Ps JN persisted as endophytic and epiphytic populations across successive in vitro potato generations.
- Intervention effect Inoculation increased potato root dry weight by 44-201%.
- Intervention effect Inoculation increased potato haulm dry weight by 14-151%.
- Intervention effect Inoculation increased potato stem length by 26-28%.
- Intervention effect Bacterization enhanced leaf hair formation by 55-110%.
- Intervention effect Bacterization enhanced secondary root branching.
- Intervention effect Bacterization enhanced total plant lignin content by 43%.
- Intervention effect Other root-colonizing bacteria had no significant plant-growth effect.
- Intervention effect Heat-killed Ps JN cells had no significant plant-growth effect.
- Observation Detached control leaves lost 55% moisture in 2.5 hours at 19 degrees C and 50% relative humidity.
- Observation Bacterized and greenhouse-acclimated leaves lost under 20% moisture.
- Mechanism Stomatal closure changes appear to explain the moisture-loss difference.
