“…Parts of this segment have been previously found in the IncHI2 plasmid pIMP4-SEM1 (encoding IMP-4 M␤L) from Salmonella enterica Typhimurium, isolated from a companion animal (19), and plasmid pKrDSM16656L from Kosakonia radicincitans, isolated from a plant (20), suggesting that this segment is involved in the survival of the microbe under environmental conditions.…”

A total of 18 Enterobacteriaceae (17 from gulls and 1 from a clinical sample) collected from Australia, carrying IncA/C plasmids with the IMP-encoding In809-like integrons, were studied. Seven plasmids, being representatives of different origins, plasmid sizes, replicon combinations, and resistance genes, were completely sequenced. Plasmid pEc158, identified in a clinical Escherichia coli ST752 isolate, showed extensive similarity to type 2 IncA/C 2 plasmids. pEc158 carried none of the bla CMY-2 -like region or ARI-B and ARI-A regions, while it contained a hybrid transposon structure. The six remaining plasmids, which were of wildlife origin, were highly similar to each other and probably were fusion derivatives of type 1 and type 2 A/C 2 plasmids. The latter plasmids contained an ARI-B region and hybrid transposon structures. In all plasmids, hybrid transposon structures containing In809-like integrons were inserted 3,434 bp downstream of the rhs2 start codon. In all cases, the one outermost 38-bp inverted repeat (IR) of the transposon was associated with the Tn1696 tnp module, while the other outermost 38-bp IR of the transposon was associated with either a Tn6317-like module or a Tn21 mer module. However, the internal structure of the transposon and the resistance genes were different in each plasmid. These findings indicated that, for the specific periods of time and settings, different IncA/C 2 plasmid types carrying In809-like elements circulated among isolates of wildlife and clinical origins. Additionally, they provided the basis for speculations regarding the reshuffling of IncA/C 2 plasmids with In809-like integrons and confirmed the rapid evolution of IncA/C 2 plasmid lineages.KEYWORDS IMP, metallo-␤-lactamases, PMLST, Klebsiella pneumoniae, Escherichia coli, Citrobacter freundii P lasmids of the IncA/C group are big molecules with a broad host range. These plasmids are commonly identified among agricultural and clinical bacterial isolates in the United States, Europe, and elsewhere. Among resistance genes, the IncA/C plasmids have often been found to disseminate bla CMY-2 -like cephalosporinase genes (1). However, recent reports describing the epidemic emergence of bla NDM metallo-␤-lactamase (M␤L) genes in Enterobacteriaceae, associated with IncA/C 2 plasmids (2), revived interest in this plasmid group. Additionally, other studies have reported the emergence of IncA/C 2 plasmids carrying the bla IMP and bla VIM M␤L genes from clinical

Abstract. Saline habitats cover a wide area of our planet and halophytes (plants growing naturally in saline soils) are increasingly used for human benefits. Beside their genetic and physiological adaptations to salt, complex ecological processes affect the salinity tolerance of halophytes. Hence, prokaryotes and fungi inhabiting roots and leaves can contribute significantly to plant performance. Members of the two prokaryotic domains Bacteria and Archaea, as well as of the fungal kingdom are known to be able to adapt to a range of changes in external osmolarity. Shifts in the microbial community composition with increasing soil salinity have been suggested and research in functional interactions between plants and micro-organisms contributing to salt stress tolerance is gaining interest. Among others, microbial biosynthesis of polymers, exopolysaccharides, phytohormones and phytohormones-degrading enzymes could be involved.

“…Nonetheless, transfer of phosphate to the plant was neither assessed nor can it be inferred from the nutrient content in shoots, and therefore, this mechanism should be verified in future experiments. Kosakonia species, previously classified into the genus Enterobacter (Brady et al 2013), have been reported as PGPR in rice (Peng et al 2009), groundnut (Madhaiyan et al 2010), and winter wheat (Witzel et al 2012). Previous studies showed that the production of phytohormones and N 2 fixation were the main plant growth-promoting mechanisms in winter wheat (Scholz-Seidel and Ruppel 1992), while in Arabidopsis thaliana, K. radicincitans not only enhanced plant growth but also induced priming of the immune response (Brock et al 2013).…”

Bio-inoculation of yerba mate seedlings (Ilex paraguariensis St. Hill.) with native plant growth-promoting rhizobacteria: a sustainable alternative to improve crop yield

In this study, the role of native plant growthpromoting rhizobacteria (PGPR) as bio-inoculants was assessed as an alternative to ameliorate Ilex paraguariensis St. Hill. growth in nursery comparing poorer (soil) versus richer (compost) substrates. Twelve rhizospheric strains isolated from yerba mate plantations were evaluated in vitro for their potential as PGPRs. Three isolates, identified as Kosakonia radicincitans YD4, Rhizobium pusense YP3, and Pseudomonas putida YP2, were selected on the basis of their N 2 fixation activity, IAA-like compound and siderophore production, and phosphate solubilization. A highly significant positive effect of bio-inoculation with the native isolates was observed in 5-month-old seedlings cultivated in soil. The highest increase was observed in seedlings inoculated with K. radicincitans YD4 with an increase of 183 % in the dry shoot weight and a 30 % increase in shoot N content. In contrast, in compost, no increment in the dry weight was observed; however, an increase in content in some macronutrients in shoots was observed. Remarkably, when plant biomass was compared between soil and compost, seedlings inoculated with K. radicincitans YD4 in soil produced the highest yields, even though higher yields could be expected in compost due to the richness of this substrate. In conclusion, bio-inoculation of yerba mate seedlings with native PGPR increases the yield of this crop in nursery and could represent a promising sustainable strategy to improve yerba mate growth in low-fertility soils.
