TLDR
This work aimed to evaluate root colonization and interaction among isolates of rhizobacteria and eucalypt species to indicate if the effect was benefic or deleterious allowing to pre-select isolates as potential growth promoter.Abstract:
This work aimed to evaluate root colonization and interaction among isolates of rhizobacteria and eucalypt species. The method used to evaluate "in vitro" root colonization was able to indicate if the effect was benefic or deleterious allowing to pre-select isolates as potential growth promoter . There was interaction among isolates of rhizobacteria and Eucalyptus species for seed germinating and seedling growth. MF2 ( Pseudomonas sp.) was the best rhizobacteria isolate for growth promotion of E. cloeziana e E. grandis. S1 (Bacillus subtilis) was the most effective for E. globulus, and Ca (Pseudomonas fulva), MF2 (Pseudomonas sp.), CIIb (Stenotrophomonas maltophilia) and S2 (B. subtilis) were the most promising isolates for the E. urophylla.read more

Emerging Role of Plant Growth Promoting Rhizobacteria in Agrobiology
TL;DR: In this paper, the authors proposed a plant growth promoting rhizobacteria (PGPR) colonize rhizosphere and reside in harmony with plants, which is known to enhance plant growth and yield components.

TL;DR: It is shown that plants respond differentially to a volatile bacterial compound through integral modulation of the immune system and the phosphate‐starvation response (PSR) system, resulting in either mutualism or immunity.

TL;DR: Concerted control of irradiance, temperature, water availability, mineral nutrition and beneficial root-associated microorganisms significantly improves adventitious rooting in eucalypts and poplars, essentially by modulating auxin and carbohydrate metabolism.

TL;DR: Three species of phosphate solubilizing bacteria were isolated from roots of weeds and the strain Pseudomonas stutzeri Khsr3 appears to be a potential candidate as bio-inoculant for saline fields.

Plant growth promoting rhizobacteria as biofertilizers
TL;DR: This review focuses on the known, the putative, and the speculative modes-of-action of PGPR, which include fixing N2, increasing the availability of nutrients in the rhizosphere, positively influencing root growth and morphology, and promoting other beneficial plant–microbe symbioses.

Molecular basis of plant growth promotion and biocontrol by rhizobacteria.
TL;DR: Substantial advances in elucidating the genetic basis of the beneficial effects of PGPRs on plants have been made, some from whole-genome sequencing projects, which will lead to a more efficient use of these strains and possibly to their improvement by genetic modification.

Screening for plant growth-promoting rhizobacteria to promote early soybean growth
TL;DR: The results suggest that rhizobacteria able to produce ACC deaminase and, to a lesser extent, β-1,3-glucanase or siderophores or those able to solubilize P in vitro may increase early soybean growth in nonsterile soil.
