“…The treatment of plants with bacteria 6CH2 in addition to herbicides initiated some positive consequences: stimulation of growth, production of chlorophyll, no need to accumulate a lot of proline. Similar effects from exposure to bacteria were observed under stresses induced by herbicides paraquat (Agafonova et al, 2016), fusilad (Osman et al, 2016), and glyphosate (Shahid and Khan, 2018). In the case of herbicides of the synthetic auxins group, it should be noted that the ability to degrade 2,4-D may be one of the factors providing a favourable effect of PGPR bacteria on plants (Jacobsen, 1997, Han et al, 2015.…”

The aim of this work was to study a new strain of microorganisms resistant to herbicides of different chemical structure and its impact on herbicidal stress in wheat (Triticum aestivum L.). Herbicides with synthetic auxins 2,4-D (2-ethylhexyl ether), dicamba (Octapon, Chistalan) and metsulfuron-methyl (Nanomet) had a phytotoxic (stress) effect on wheat plants, decreasing their weight up to 11%, reducing the amount of chlorophylls up to 10% and increasing the proline quantity by 2.5-5.7 times in leaves. The Pseudomonas avellanae strain 6CH2 was isolated from chemical factory soil and had a number of useful properties: suppression of phytopathogenic Fusarium, herbicide-resistance, synthesis auxins and molecular nitrogen fixation. Its special features did not disappear under the influence of herbicides. Because of these properties, P. avellanae strain 6CH2 had an anti-stress effect on wheat plants if they were jointly treated with herbicides and bacteria. Spraying with herbicides increased the concentration of proline in wheat leaves by 1.7-2.8 times, while bacterial addition made it at least the same as in the control group. Inoculation with bacteria P. avellanae strain 6CH2 increased the total chlorophyll amount by 1.19-1.26 times against the background of herbicidal stress. Thus, bacteria P. avellanae strain 6CH2 can be used as an anti-stress agent when spraying wheat crops with herbicides.

“…Rhodanobacter bacteria have been proved to be highly positively correlated with available nitrogen in soil . It has been suggested that Methylophilu, Sphingomonas, and Rhizomicrobium could promote plant growth (Agafonova et al 2016;Asaf et al 2018;Wei et al 2019). We speculated that these bacteria might promote the colonization of Rhizobium and affect the nodule formation of pea roots.…”

Background and aims Endophytic bacteria from legume roots and nodules play important roles in regulating plant growth and health. However, little is known about how the endophytic bacteria community changes and how it interacts with each other throughout the plant life cycle. Methods We collected twenty pea cultivars to study the composition and structure of endophytic bacterial community during the whole developmental period using Illumina sequencing of 16S rRNA gene. Results Here we show that the development period significantly affected the structure of root endophytic bacterial community and peas recruit different root microbes during different developmental stages. The complexity of microbial community first increased and then decreased with the growth of pea. Rhizobium began to accumulate in pea seedling roots, and the content peaked at flowering stage and remained at high levels during the mature stage. In the flowering and mature stage, the relative abundance of Pseudomonas increased. Conclusions These findings can deepen the overall understanding of the community structure and interaction network of endophytic bacteria from pea root and nodules, and provide a detail for the establishment of root endophytic bacteria throughout the plant life cycle.
