Aims The current study was aimed to evaluate the beneficial effects and bioremediation potential of a Cd‐tolerant bacterial strain, Serratia sp. CP‐13, on the physiological and biochemical functions of Linum usitatissimum L., under Cd stress. Methods and Results The bacterial strain was isolated from the wastewater collection point of Chakera, Faisalabad, Pakistan, as this place contains industrial wastewater of the Faisalabad region. The Serratia sp. CP‐13, identified through 16S rRNA gene sequence analysis, exhibited a significant phyto‐beneficial potential in terms of in vitro inorganic phosphate solubilization, indole‐3‐acetic acid production and 1‐aminocyclopropane‐1‐carboxylic acid deaminase activity. Effects of Serratia sp. CP‐13 inoculation on L. usitatissimum were evaluated by growing the plants in CdCl2 (0, 5 or 10 mg kg−1 dry soil)‐spiked soil. Without inoculation of Serratia sp. CP‐13, Cd stress significantly reduced the plant biomass as well as the quantity of proteins and photosynthetic pigments due to enhanced H2O2, malondialdehyde (MDA) contents and impaired nutrient homeostasis. Subsequently, Serratia sp. CP‐13 increased the plant fresh and dry biomass, plant antioxidation capacity, whereas it decreased the lipid peroxidation under Cd stress. In parallel, Serratia sp. inoculation assisted the Cd‐stressed plants to maintain an optimum level of nutrients (K, Ca, P, Mg, Fe and Mn). Conclusions The isolated bacterial strain (Serratia sp. CP‐13) when applied to Cd‐stressed L. usitatissimum inhibited the Cd uptake, reduced Cd‐induced lipid peroxidation, maintained the optimum level of nutrients and thereby, enhanced L. usitatissimum growth. The analysis of bio‐concentration and translocation factor revealed that L. usitatissimum with Serratia sp. CP‐13 inoculation sequestered Cd in plant rhizospheric zone. Significance and Impact of the Study Serratia sp. CP‐13 inoculation is a potential candidate for the development of low Cd‐accumulating linseed and could be used for phytostabilization of Cd‐contaminated rhizosphere/soil colloids.

“…Knowledge of detailed interactions between bacteria and plant is limited, even for many commercially available PGP bioformulations (Calvo et al 2014). Most studies have been conducted on annual crop plants, such as radish, lettuce and sunflower (Berger et al 2015;Sahin et al 2015;Shahid et al 2015), leaving the interaction between PGP bacteria and perennial arboreal plants poorly explored (Magnin-Robert et al 2007;Magnin-Robert et al 2013;Bashan et al 2014;Gómez-Lama Cabanás et al 2014;Aziz et al 2015).…”

Root-associated bacteria promote grapevine growth: from the laboratory to the field

Background and Aims Laboratory and greenhouse experiments have shown that root-associated bacteria have beneficial effects on grapevine growth; however, these effects have not been tested in the field. Here, we aimed to demonstrate whether bacteria of different geographical origins derived from different crop plants can colonize grapevine to gain a beneficial outcome for the plant leading to promote growth at the field scale. Methods To link the ecological functions of bacteria to the promotion of plant growth, we sorted fifteen bacterial strains from a larger isolate collection to study in vitro Plant Growth Promoting (PGP) traits. We analysed the ability of these strains to colonise the root tissues of grapevine and Arabidopsis using greenfluorescent-protein-labelled strain derivatives and a cultivation independent approach. We assessed the ability of two subsets randomly chosen from the 15 selected strains to promote grapevine growth in two field-scale experiments in north and central Italy over two years. Parameters of plant vigour were measured during the vegetative season in de novo grafted vine cuttings and adult productive plants inoculated with the bacterial strains. Results Beneficial bacteria rapidly and intimately colonized the rhizoplane and the root system of grapevine. In the field, plants inoculated with bacteria isolated from grapevine roots out-performed untreated plants. In both the tested vineyards, bacteria-promotion effects largely rely in the formation of an extended epigeal system endowed of longer shoots with larger diameters and more nodes than non-inoculated plants.Conclusions PGP bacteria isolated in the laboratory can be successfully used to promote growth of grapevines in the field. The resulting larger canopy potentially increased the photosynthetic surface of the grapevine, promoting growth.
