General Information

General Information	Comment	Organism
physiological function	the rhizosphere bacterium containing 1-aminocyclopropane-1-carboxylate deaminase increases growth and photosynthesis of pea (Pisum sativum cv. Alderman) plants under salt stress by limiting Na+ accumulation. When pea is grown with 70 and 130 mM NaCl, the ACC-deaminase containing rhizobacterium Variovorax paradoxus strain 5C-2 increases total biomass by 25 and 54% respectively. Nutrient flow modelling shows that Variovorax paradoxus strain 5C-2 increases K uptake and root to shoot K flow, but decreases Na flow and increases Na deposition in roots. Thus, shoot K+:Na+ ratio increases following Variovorax paradoxus 5C-2 inoculation. At 70 and 130 mM NaCl, rhizobacterial inoculation decreases stomatal resistance by 14 and 31%and decreases xylem balancing pressure by 7 and 21%, respectively. Furthermore, rhizobacterial inoculation improves photosynthetic efficiency (Fv/Fm) by 12 and 19% and increases maximal electron transport rate (ETR) by 18 and 22% at 70 and 130 mM NaCl, respectively	Variovorax paradoxus
