“…Neither soil properties nor oil concentration responded to the PGPB inoculation (data not shown) in our field, in contrast to other studies where PGPB enhanced the rhizoremediation of polluted soils (Pajuelo et al, 2011;Vershinina et al, 2012;Bhattacharyya and Jha, 2012). However, the oil tolerance ability of PGPB strains, the local field factors and the hydrocarbon composition were different from these studies.…”

Soil contamination by petroleum hydrocarbons is a global problem. Phytoremediation by plants and their associated microorganisms is a cost-effective strategy to degrade soil contaminants. In boreal regions the cool climate limits the efficiency of phytoremediation. The planting of oil-tolerant perennial crops, especially legumes, in oil-contaminated soil holds promise for great economic benefits for bioenergy and bio-fertilizer production while accelerating the oil degradation process. We established a multi-year field experiment to study the ecological and agronomic feasibility of phytoremediation by a legume (fodder galega) and a grass (smooth brome) in a boreal climate. In 40 months, soil oil content decreased by 73%-92%, depending on the crop type. The oil degradation followed first-order kinetics with the reduction rates decreasing as follows: bare fallow > galega-brome grass mixture > brome grass > galega. Surprisingly, the presence of oil enhanced crop dry matter and nitrogen yield, particularly in the fourth year. The unfertilized galega-brome grass mixture out-yielded the N-fertilized pure grass swards over years by an average of 33%. Thus, a perennial legume-grass mixture is both ecologically and agronomically sustainable as a cropping system to alleviate soil contamination in the boreal zone, with considerable potential for bioenergy and bio-fertilizer production.

“…Production of metabolite with antimicrobial activity, or competition for nutrients and exclusion from the ecological niche of colonizing microorganisms, has been suggested as a possible mechanism (BacilioJiménez et al, 2001). It has been proposed that endophytically resident bacteria may be strategically available at the right place and at the right time for suppression of vascular wilt diseases and probably have the unique ability to survive inside plants with little or no microbial competition; the endophytic bacterium and its host plant can coevolve in a communicative and cooperative manner that leads to inhibiting and suppressing vascular (wilt) diseases (Antonyuk and Evseeva, 2006;Bright and Bulgheresi, 2010;Vershinina et al, 2012).…”

“…Plant lectin functions have been speculated, among them; these proteins participate as a binding factor in the interaction between plants and microorganisms (Carlini and Grosside-Sá, 2002;Souza et al, 2011). Seeds, roots, flowers as well as leaves may contain considerable concentrations of lectins (Coelho and Silva, 2000;Silva et al, 2014); it is believed that in these organs, lectins could favor the symbioses with endophytic organisms (Antonyuk and Evseeva, 2006;Vershinina et al, 2012).…”

Bauhinia monandra leaves are well known hypoglycemic agent in Brazilian popular medicine from which a galactose specific lectin (BmoLL) has been purified in milligram quantities. In this work, the antimicrobial activity of endophytes isolated from B. monandra leaves and the ability of BmoLL to agglutinate the microorganisms were evaluated. After disinfection, leaves of B. monandra were fragmented and distributed in Petri plates leading to isolation of fungi (37 strains) and both Grampositive (26 strains) and negative bacteria (6 strains). A preliminary antimicrobial assay revealed that 62% of bacterial strains were active, while no antagonist action was detected with fungi. However, only 2 strains were able to excrete the antimicrobial compounds: Pseudomonas aeruginosa UFPEDA598 inhibited Aspergillus niger, Fusarium moniliform, Fusarium oxysporum, Micrococcus luteus, Staphylococcus aureus, Bacillus subtilis and PE(24)C1 inhibited Candida sp. strains, M. luteus and S. aureus. On the other hand, BmoLL did not show any antimicrobial action, but it was able to agglutinate the active strain P. aeruginosa UFPEDA598. The BmoLL-Pseudomonas interaction could promote a defense against the attack of phytopathogenic microorganisms in plants through a P. aeruginosa metabolic production mechanism. The lectins/endophytes interaction could be a new line to unravel defense mechanisms against phytopathogenic organisms.

“…For example, tomatoes were obtained that produce N-acyl-homoserine lactone, which is a regulator of the expression of quorum sensing genes [1]. We also obtained tomato plants transformed with the lectin gene psl, which improved the colonization of these plants with growthstimulating bacteria R. leguminosarum [2,3]. Bacterial agglutinins, in particular the RapA1 protein, isolated from some rhizobia strains, can also serve as a component that improves associative interactions [4].…”

Rhizobia can serve as beneficial associative bacteria for many crops, including tomato. There are a number of studies to improve this associative interaction by transforming plants with various genes, in particular, the genes of plant lectins and bacterial agglutinins. It is known that glutathione (GSH) plays an important role in the formation of associative symbiosis between plants and bacteria. The aim of this work was to study the redox state of glutathione in various artificial symbiotic systems on the roots of tomato plants, transformed with the lectin gene psl and the bacterial agglutinin gene rapA1 after treatment of rhizobia. Evaluation of the glutathione content in the roots of transgenic plants with psl gene showed a significant increase in the GSH content and the GSH/GSSG ratio was 4.6, while the adsorption of bacteria on the roots of these plants increased 9 times. In the transgenic roots with the rapA1 gene bacteria were sorbed three times more in comparison with the control plants, and the GSH/GSSG ratio was 4.1. The results obtained demonstrate the promise of studying the redox state of glutathione for assessing the effectiveness of artificial symbiotic systems.
