“…These strains were able to degrade 2,4-dichlorophenoxyacetic acid (2,4-D). Endophytic bacteria able to degrade several aromatic hydrocarbons such as benzene, toluene, ethyl benzene and xylene were also isolated from roots, stems and leaves of different cultivars of poplar tree (Porteous Moore et al, 2006;Taghavi et al, 2011). These strains showed marked spatial compartmentalization within the plant, proposing there species-specific and non-specific relations between bacteria and plants.…”

“…The endophytic microbiome, the rhizosphere hosting potential recruits, and the interrelationships between microbes and the plant host should be considered by an integrated approach for crop yield improvement. Furthermore, endophytes have an enormous potential to degrade organic pollutants (Viñas et al 2005, Taghavi et al 2011, and an understanding of the processes that lead to enrichment of specific endophyte species due to environmental stress will offer great benefits for e.g. remediation of polluted soils and higher biomass yields of energy crops.…”

Background From the point of view of systems biology, the plant is considered a super organism that consists of the plant per se and numerous populations of pro-and eukaryotic microbial organisms. Each plant species hosts a genotype-specific core microbiome, dynamically responding to environmental cues, such as soil quality. In the plant endosphere, microbial organisms are an indispensable part of the information processing system, and the plant-endophyte interrelationships result in mutual adjustments through this system. Within the plant tissue

“…Highly water-soluble contaminants readily enter the xylem stream before they are degraded by rhizospheric microbes (Weyens et al 2009c). This may compromise health of the plant and reduce phytoremediation efficiency, but since the contaminants reside within the plant tissues for a significant amount of time, endophytic bacteria are well-suited for in planta detoxification of these compounds (Taghavi et al 2011).…”

Phytoremediation: recent advances in plant-endophytic synergistic interactions

Background Plant-endophyte partnership provides an excellent gateway toward restoration of contaminated ecosystems. The interactions between both partners can be manipulated by introducing novel catabolic/ metabolic genes into host plant or endophytic bacteria genomes. The potential of the engineered organisms to degrade or accumulate contaminants is much wider than their wild relatives. Scope This review covers the recent developments for engineering catabolic/metabolic genes from a wide range of sources into plants or endophytic bacteria for the development of modified plant-endophyte interactions. Genetic alteration of plants promises enhanced catabolism by plant's own enzymatic machinery or greater contaminant uptake/accumulation for subsequent in planta detoxification by complementary endophytes. On the other hand, bacteria may also be engineered to enhance the potential for degradation or alteration of catabolic pathways, either to protect the host plant against phytotoxicity or to improve the overall efficiency of phytoremediation in planta, a situation especially suitable when hydrophilic compounds fail to be degraded by rhizospheric microbes due to the rapid uptake by plants. This is followed by discussion on kinetic parameters controlling phytoremediation. Conclusions It is hypothesized that transgenic approach can result in synergistic and effective plant-endophyte partnerships for wider-range and enhanced capabilities of degrading and/or detoxifying contaminants.
