“…Additionally, the stimulation of different crops by PGPR has been verified in both laboratory and field trials. P. putida and P. fluorescens have been found to play a considerable role in root and shoot elongation in canola, lettuce, and tomato (Kloepper et al, 1988; Hall et al, 1996) as well as crop yields in potato, radish, rice, sugar beet, tomato, lettuce, apple, citrus, beans, some ornamental plants, and wheat (Kloepper et al, 1988; Lemanceau, 1992; Kloepper, 1994). Interestingly, a study by Li et al (2000) and Madhaiyan et al (2006) observed that PGPR with ACC deaminase mutants could not modulate plant growth whereas ACC deaminase transgenic canola plants showed improved growth under salinity stress (Sergeeva et al, 2006).…”

Soil salinity, being a part of natural ecosystems, is an increasing problem in agricultural soils throughout the world. Pseudomonas frederiksbergensis OS261 has already been proved to be an effective bio-inoculant for enhancing cold stress tolerance in plants, however, its effect on salt stress tolerance is unknown. The main aim of the present study was to elucidate P. frederiksbergensis OS261 mediated salt stress tolerance in red pepper. The plants were exposed to a salt stress using NaCl at the concentrations of 50, 100, and 150 mM after 12 days of transplantation, while plant growth and enzyme activity were estimated 50 days after sowing. The height in P. frederiksbergensis OS261 inoculated plants was significantly increased by 19.05, 34.35, 57.25, and 61.07% compared to un-inoculated controls at 0, 50, 100, and 150 mM of NaCl concentrations, respectively, under greenhouse conditions. The dry biomass of the plants increased by 31.97, 37.47, 62.67, and 67.84% under 0, 50, 100, and 150 mM of NaCl concentrations, respectively. A high emission of ethylene was observed in un-inoculated red pepper plants under salinity stress. P. frederiksbergensis OS261 inoculation significantly reduced ethylene emission by 20.03, 18.01, and 20.07% at 50, 100, and 150 mM of NaCl concentrations, respectively. Furthermore, the activity of antioxidant enzymes (ascorbate peroxidase, superoxide dismutase, and catalase) also varied in the inoculated red pepper plants. Salt stress resistance in the bacterized plants was evident from the improved antioxidant activity in leaf tissues and the decreased hydrogen ion concentration. Thus, we conclude that P. frederiksbergensis OS261 possesses stress mitigating property which can enhance plant growth under high soil salinity by reducing the emission of ethylene and regulating antioxidant enzymes.

“…Researchers reported yield increase in potato, tomato, apple, citrus, turnip, sugar beet, broad bean, rice, and wheat with Pseudomonas putida and Ps. fluorescens bacteria inoculations (Suslov, 1982;Kloepper et al, 1988;Lemanceau, 1992;Kloepper, 1994). The amount of N + P applied to soil may be reduced by about 20% with triple bacteria inoculation.…”

“…Microbial inoculations should contribute to improved plant growth and health while they reduce chemical inputs. Among the different microbial groups which have been proposed for plant inoculation, much attention has been given to glomalean fungi and fluorescent pseudomonads (Weller, 1988;Lemanceau, 1992;Gianinazzi et al, 1995;Cordier et al, 2000).…”

Summary• The ability of fluorescent pseudomonads and glomalean fungi to promote plant growth has been reported many times. However, little is known of their effects on root morphogenesis. Growth and root morphogenesis were compared in tomato (Lycopersicon esculentum) plants inoculated or not with a model strain of Pseudomonas fluorescens (A6RI) or with the arbuscular mycorrhizal fungus Glomus mosseae (BEG12).• Plants were cultivated in a sandy-loam soil mixed with sand at two different ratios (2 : 1 and 1 : 2), in gnotobiotic conditions. Plant growth was evaluated by measuring root and shoot fresh weight, and various morphometric parameters were compared.• Growth of control plants was less in the 1 : 2 than in the 2 : 1 soil : sand mixture, and root morphogenesis was also significantly altered by soil:sand mixture. P. fluorescens A6RI promoted plant growth and increased total root length, surface area and volume in the more fertile soil:sand mixture (2 : 1) whereas G. mosseae BEG12 did the same in the less fertile soil : sand mixture (1 : 2).• The relevance of differences between the two types of organisms in relation to the environmental conditions favourable for the expression of their beneficial effects is discussed in the context of microbial inoculation.
