“…As a result, it can decrease the intensity of root injury, cause stomata to close and reduce transpiration tension, and interfere with the ability of the plant body to absorb water, which inhibits its physiological activity and causes a decrease in the photosynthetic rate [ 59 ]. Eventually, the photosynthetic organs of plants are destroyed, and the photosynthetic rate is reduced [ 60 ]. Reduced Na + contents and a higher K + /Na + ratio leading to stress alleviation were also observed by Yasin et al [ 39 ] in PGPR-inoculated Capsicum annum growing under salt stress.…”

Certain plant growth-promoting bacteria (PGPB) reduce salt stress damage in plants. Bacillus subtilis HG-15 is a halotolerant bacterium (able to withstand NaCl concentrations as high as 30%) isolated from the wheat rhizoplane in the Yellow River delta. A qualitative and quantitative investigation of the plant growth-promoting characteristics of this strain confirmed nitrogen fixation, potassium dissolution, ammonia, plant hormone, ACC deaminase, and proline production abilities. B. subtilis HG-15 colonization of wheat roots, stems, and leaves was examined via scanning electron microscopy, rep-PCR, and double antibiotic screening. After inoculation with the B. subtilis HG-15 strain, the pH (1.08–2.69%), electrical conductivity (3.17–11.48%), and Na+ (12.98–15.55%) concentrations of rhizosphere soil significantly decreased ( p < 0.05 ). Under no-salt stress (0.15% NaCl), low-salt stress (0.25% NaCl), and high-salt stress (0.35% NaCl) conditions, this strain also significantly increased ( p < 0.05 ) the dry weight (17.76%, 24.46%, and 9.31%), fresh weight (12.80%, 20.48%, and 7.43%), plant height (7.79%, 5.86%, and 13.13%), and root length (10.28%, 17.87%, and 48.95%). Our results indicated that B. subtilis HG-15 can effectively improve the growth of wheat and elicit induced systemic tolerance in these plants, thus showing its potential as a microbial inoculant that can protect wheat under salt stress conditions.

Eventually, the photosynthetic organs of plants are destroyed and photosynthetic rate is reduced [51,52]. It is well known that sodium ions can interact with negatively charged plasma membranes, resulting in depolarization of transmembrane potentials and changes in H + -ATPase activity, which in turn interfere with the uptake of cations such as Mg 2+ and affect chlorophyll biosynthesis [53].…”

Background : Certain plant growth-promoting bacteria (PGPB) reduce salt stress damage in plants. Bacillus subtilis HG-15 is a halotolerant bacterium (able to withstand NaCl concentrations as high as 30%) isolated from the wheat rhizoplane in the Yellow River delta. A qualitative and quantitative investigation of the plant growth-promoting characteristics of this strain confirmed nitrogen fixation, potassium dissolution, and ammonia, plant hormone, 1-aminocyclopropane-1-carboxylic acid deaminase, and proline production abilities. B. subtilis HG-15 colonization of wheat roots, stems, and leaves was examined via scanning electron microscopy , rep-PCR, and double antibiotic screening.Results : Compared with a no B. subtilis HG-15 treatment control, in rhizosphere soil inoculated with the HG-15 strain, the pH (1.08–2.69%), electrical conductivity (3.17–11.48%), and Na + (12.98–15.55%) concentrations significantly decreased ( p < 0.05). Inoculation with the HG-15 strain increased the total N, available N, organic matter, K + , Ca 2+ , and Mg 2+ concentrations in the rhizosphere soil of wheat. Under non-salt stress (0.15% NaCl), low-salt stress (0.25% NaCl), and high-salt stress (0.35% NaCl) conditions, respectively, this strain also significantly increased ( p < 0.05) the dry weight (17.76%, 24.46%, 9.31%), fresh weight (12.80%, 20.48%, 7.43%), plant height (7.79%, 5.86%, 13.13%), root length (10.28%, 17.87%, 48.95%), and other wheat parameters. Through redundancy analysis and Pearson correlation analyses, photosynthesis, biomass accumulation, and osmotic regulation by the wheat plants showed a significant negative correlation with pH, EC, and Na + concentrations in rhizosphere soil.Conclusions : Our results indicated that B . subtilis HG-15 can effectively improve the growth of wheat and elicit induced systemic tolerance in these plant, thus, showing its potential as a microbial inoculant that can protect wheat in salt stress conditions. Furthermore, we determined that the rhizoplane of saline-alkali land plants is an important reservoir for salt-tolerant PGPB.

“…In Mediterranean countries, drought and salt have been considered as the most important environmental stresses limiting the growth, development and production of crop plants. In general, drought and salt challenge cause a decrease in photosynthetic performance and consequently lead to marked reductions in biomass and yield (Valifard et al 2015). Indeed, drought and salt induce a range of morphological, physiological and biochemical responses in plants such as reduction in leaf area and rate of cell expansion, stomatal closure, loss of turgor, reduction in leaf water potential, osmotic adjustment and increase in antioxidant enzyme activities (Srivastava & Srivastava 2014;Ghahfarokhi et al 2015;Le Gall et al 2015).…”

Identification and characterization of two faba bean (Vicia faba L.) WRKY transcription factors and their expression analysis during salt and drought stress

SUMMARYDrought and salinity are two major environmental factors limiting faba bean growth, leading to considerable reduction in their productivity. The WRKY gene family act as major transcription factors that might play an important role in abiotic stress tolerance. In the present study, two partial sequences sharing significant homology with known WRKY genes were isolated from faba bean by polymerase chain reaction (PCR) amplification using degenerate primers targeting the well-conserved WRKY domain. The isolated WRKY gene fragments were designated as VfWRKY1 and VfWRKY2 showing 62% similarity between them. Sequence and phylogenetic analyses revealed that VfWRKY1 and VfWRKY2 belong to WRKY group I and could be grouped with their orthologues from other plant species. The gene expression profile of VfWRKY1 and VfWRKY2 in faba bean showed that they are significantly accumulated in various plant organs. Further, quantitative real-time PCR analysis showed that both transcripts were responsive to drought and salt stress, and also they are genotype dependent, meaning that different faba bean cultivars respond in a different way to drought and salt challenge. The expression patterns obtained suggest the important roles of VfWRKY1 and VfWRKY2 in drought and salt stress response and tolerance. This knowledge might be helpful in the identification of drought-tolerant cultivars and provide potential candidate markers for faba bean breeding in order to develop osmotic-stress-tolerant cultivars.
