“…isolate ESA 0014. These results corroborate results from other studies, in which efficient diazotrophic and phytohormone producing bacteria were isolated from cultivated (Kuss et al, 2007;Ferrara et al, 2012;Silva et al, 2013;Santos et al, 2015) and wild species (Doty et al, 2009;Jha et al, 2012).…”

“…In the present study, among the 16 bacterial isolates evaluated, only two were not related to Enterobacteriaceae or Firmicutes, and they were classified as Rhizobium and stenotrophomonas. Both genera are known to include PGPB associated with non-legume crops and wild species (Ferrara et al, 2012;Jha et al, 2012;Silva et al, 2013). …”

“…Regarding wild non-legume species, the search for bacterial isolates able to promote plant growth has been carried out worldwide since the 1980's (Reinhold et al, 1987;Bilal et al, 1990;Doty et al, 2009;Lopez et al, 2011;Jha et al, 2012;Zahid et al, 2015). In Brazil, few plant groups have been studied only in the last few years (Costa and Melo, 2012;Fernandes Júnior et al, 2013;Kavamura et al, 2013).…”

Plant species that naturally occur in the brazilian Caatinga (xeric shrubland) adapt in several ways to these harsh conditions, and that can be exploited to increase crop production. among the strategic adaptations to confront low water availability, desiccation tolerance stands out. Up to now, the association of those species with beneficial soil microorganisms is not well understood. The aim of this study was to characterize Tripogon spicatus diazotrophic bacterial isolates from the Caatinga biome and evaluate their ability to promote plant growth in rice. sixteen bacterial isolates were studied in regard to their taxonomic position by partial sequencing of the 16s rRna gene, putative diazotrophic capacity, in vitro

“…Hence, the presence of the dinitrogenase reductase (nif) gene family is frequently used in microbiota screens for identification of beneficial strains (Juraeva et al 2006). The nifH gene has been found in bacterial isolates from roots of Salicornia brachiata belonging to the genera Brachybacterium, Brevibacterium and Zhihengliuella (Jha et al 2012).…”

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.

“…The direct mechanisms are nitrogen fixation (N 2 ), phosphate solubilization, insoluble iron chelation through the production of siderophores and phytohormones, such as auxins, cytokinins, and gibberellins (Oliveira et al, 2003;Tsavkelova et al, 2007;Jha et al, 2012).…”

Endophytic microorganisms are able to promote plant growth through various mechanisms, such as production of plant hormones and antimicrobial substances, as well as to provide the soil with nutrients, for instance, inorganic phosphate. This study aimed to evaluate the potential of endophytic bacteria isolated from cashew leaves to produce substances involved in the promotion of plant growth, such as indole-3-acetic acid, the phosphate solubilization capacity, and the antimicrobial activity. For this, 31 isolate samples were used, out of which 17 (54.8%) produce indole-3-acetic acid in concentrations ranging from 11.79 to 145.85 µg.mL . It was observed that Fusarium oxysporum and Colletotrichum sp. were inhibited by 70 and 40% of the strains, respectively. It was found out that five bacteria (25%) were Gram-positive, predominantly the species Staphylococcus saprophyticus (100%), while 15 bacteria (75%) were Gram-negative. Out of these, 4 (26.6%) and 3 (20%) belong to the species Escherichia coli and Shigella flexneri, respectively. Studying the endophytic population is something important due its biotechnological applications, because it has a great potential for promoting plant growth.
