“…Our results agreed with those of Ahmad et al (2006), who also reported that ICs production was the most prevalent plant growth promoting characteristic in the majority of their isolates. High numbers of ICs-producing bacteria have also been documented by other studies Granada et al 2013;Souza et al 2013). Table 1.…”

“…Partial sequences of the 16S rRNA gene (roughly 450 bp) from each isolate were amplified using the primers U968 (AACGCGAAGAACCTTAC) and L1401 (CGGTGTGTA CAAGACCC) (Felske et al 1997), which cover the region between nucleotides 968 and 1401 of the Escherichia coli 16S rRNA gene, and using the conditions described in Souza et al (2013). Thermal cycling was performed according to Garbeva et al (2003).…”

“…The experimental units consisted of pots (15 X 20 cm) sterilized with 0.7% sodium hypochlorite solution before seeding. Barley seeds were surface-disinfected as described by Souza et al (2013) and were planted in sterile vermiculite, 2 cm below the surface. Three bacterial isolates (JC57, SB41, and VA7) were grown in LB medium with agitation (125 rpm) for 48 h at 28°C.…”

“…Root-colonizing plant beneficial bacteria, commonly referred to as plant growth-promoting bacteria (PGPB), are rhizospheric bacteria that can enhance plant growth using a wide variety of direct and indirect mechanisms (Glick 2012). The favorable effects of PGPB inoculation on plant growth have been widely studied Glick 2012;Granada et al 2013;Souza et al 2013).…”

The occurrence of associations between bacteria and plant roots may be beneficial, neutral or detrimental. Plant growth promoting (PGP) bacteria form a heterogeneous group of beneficial microorganisms that can be found in the rhizosphere, the root surfaces or in association with host plant. The aim of this study was to isolate and characterize PGP bacteria associated to barley plants (Hordeum vulgare L.) aiming a future application as agricultural inoculant. One hundred and sixty bacterial strains were isolated from roots or rhizospheric soil of barley based on their growth in nitrogen-free selective media. They were evaluated for their ability to produce indolic compounds (ICs) and siderophores, and to solubilize tricalcium phosphate in in vitro assays. Most of them (74%) were able to synthesize ICs in the presence of the precursor L-tryptophan, while 57% of the isolates produced siderophores in Fe-limited liquid medium, and 17% were able to solubilize tricalcium phosphate.

Abstract. Compared to their annual analogues, perennial grain cropping systems provide various beneficial attributes for the environment and ecosystem services related to resource use efficiency, soil erosion, and soil conservation. However, there is only limited understanding of the multiple biotic interactions in perennial cropping systems and their potential effects on the crop, involving plant growth-promoting and pathogenic microorganisms, beneficial and detrimental faunal organisms below-and above-ground, weeds, and overall biodiversity effects. We use information from studies carried out in managed and natural perennial systems of analogous structure such as perennial energy crop production systems and grasslands to highlight and specify biotic interactions and processes, which potentially constitute advantages and constraints in developing perennial grain cropping systems. Concerning the relevance of soil microorganisms and potential perennial crop breeding goals, we focus on a range of plant-microbe interactions in the rhizosphere involved in biofertilization, phytostimulation, and biological control of soil pathogens. We consider relationships within the faunal community emphasizing arthropod pests and their natural enemies, as well as crop-weed interactions. Based on these outcomes and in comparison with annual systems, we discuss and compile benefits, options, and limitations of management of crop-associated biotic interactions and biodiversity, which might contribute to reproducible and sustainable effects of perennial grain crop productivity. We conclude that management strategies for perennial grain cropping systems depend much more on ecological processes and interactions operating in natural ecosystems than those in annual cropping systems. Consequently, the use of agrochemicals for pest, weed, and disease control, as well as the use of synthetic fertilizers, counteracts the principle functions of the system and would strongly degrade the potential of biotic benefits. We also found that there is only vague information on the long-term productivity and cultivation period of perennial grain crops, the specific management operations of replacement, and the potential development and management of weed and pest populations. Overall, an advanced understanding of interactions between the crop and its biotic environment provides the opportunity to manipulate specific functional traits of crop-associated organisms for improved management and crop productivity, but significant research challenges for implementation of perennial grain crops still remain.
