“…Thus, actual comparisons between the 2 experiments are difficult to make. Present results also conflict with our previous report, in which the same plant species (Phaseolus vulgaris L. 'Guangzhouyuan') was used to investigate the effect of elevated O 3 on mycorrhizal colonization (Wang et al 2011). Results showed that overall mycorrhizal colonization was slightly decreased by 80 and 120 nL/L O 3 , but the proportional frequency of hypha significantly decreased and the proportional frequency of spores and vesicles significantly increased with elevated O 3 .…”

“…BGCBJ07), purchased from Beijing Academy of Agricultural and Forestry Sciences (Beijing, China), was propagated by the host plant of broomcorn (Sorghum vulgare). Glomus aggregatum was proved to have a good symbiotic relationship with snap bean (Phaseolus vulgaris L.) in a previous experiment (Wang et al 2011). AM inoculum was a mixture of spores, mycelium, sandy soil, and root fragments.…”

“…However, most of the above results are based on experiments in an ambient O 3 environment; few studies have addressed the influence of AM on rhizosphere microorganisms under elevated O 3 . Presently, only some studies provide assessment of the impacts of elevated O 3 on mycorrhizal colonization and structure (e.g., Brewer and Heagle 1983;McCool and Menge 1984;Miller et al 1997) and the effects of AM inoculation on plant growth and nutrition status (Duckmanton and Widden 1994;Fangmeier et al 2002;Wang et al 2011;Cui et al 2013). Other studies on AM under elevated O 3 are few.…”

“…In China, snap bean is a promising legume for local consumption, and planting area is more than 1.21 × 10 6 hm 2 . Effects of elevated O 3 on snap bean have attracted much attention (Leitao et al 2003;Guidi and Degl'Innocenti 2008;Flowers et al 2007;Wang et al 2011). In this study, we selected 2 snap bean genotypes with different O 3 sensitivity (R123, an O 3 -tolerant plant; S156, an O 3 -sensitive plant) as host plant to investigate the effects of elevated O 3 on microbial biomass and community structure in the rhizosphere after AM inoculation.…”

Elevated ozone (O₃) generally affects microbial biomass and community structure in rhizosphere, but these effects are unclear in mycorrhizal plants because arbuscular mycorrhizal (AM) fungi often benefit microbial growth in the rhizosphere. Here, we investigate the effects of elevated O₃ on microbial biomass and community structure in the rhizosphere of mycorrhizal snap bean (Phaseolus vulgaris L.) with different O₃ sensitivity (R123: O₃-tolerant plant; S156: O₃-sensitive plant) based on the phospholipid fatty acids (PLFAs) method. Compared with ambient O₃, elevated O₃ significantly decreased mycorrhizal colonization rates in the 2 genotypes, especially in S156 plants. The wet masses of shoot and root were decreased by elevated O₃ in the 2 genotypes independent of AM inoculation, but they were higher in the mycorrhizal plant than in the nonmycorrhizal plant independent of O₃ concentration. Elevated O₃ significantly decreased the relative proportion of specific fungal PLFAs in the nonmycorrhizal plant, but this effect disappeared in the mycorrhizal plant. The relative proportions of specific PLFAs of other microbial groups (Gram-positive, Gram-negative, and actinomycete) in the rhizosphere and all specific PLFAs in the hyphosphere were not affected by elevated O₃ independent of AM inoculation. In the rhizosphere of the 2 genotypes, microbial community structure was changed by AM inoculation and elevated O₃ as well as by their interaction; in the hyphosphere, however, microbial community structure was changed by elevated O₃ only in R123 plants. It is concluded that AM inoculation can offset negative effect of elevated O₃ on fungal biomass but seems to enhance shift of microbial community structure in rhizosphere under elevated O₃.

“…However, recently, the approach of soil microbial inoculation to ameliorate salinity stress in plants [19] has gained more attention. Microbial inoculants, such as arbuscular mycorrhizal fungi (AMF) and Rhizobium, have been previously studied as they are ubiquitous in soil and provide a low-cost natural means of improving nutrient acquisition in stressed soil under adverse environmental conditions [20][21][22][23]. Specifically, soil inoculation with AMF and Rhizobium can potentially reduce environmental pollution by lowering the application of synthetic fertilizers in the soil [24,25].…”

Effect of Salinity Stress and Microbial Inoculations on Glomalin Production and Plant Growth Parameters of Snap Bean (Phaseolus vulgaris)

et al. 2019

Salinity is a major abiotic stress that can adversely affect plant growth, yield, other physiological parameters, and soil health. Salinity stress on biomass production of salt-sensitive crops, like snap bean (Phaseolus vulgaris), is a serious problem, and specifically in South Florida, USA, where saline soils can be found in major agricultural lands. Research studies focused on the ‘snap bean–Rhizobium–arbuscular mycorrhizal fungi (AMF)’ relationship under salinity stress are limited, and fewer studies have evaluated how this tripartite symbiosis affects glomalin production (GRSP), a glycoprotein released by AMF. A shade house experiment was conducted to elucidate the effects of three microbial inoculations (IC = inoculation control; IT1 = AMF and IT2 = AMF + Rhizobium) on three salinity treatments (SC = salinity control 0.6 dS m−1, S1 = 1.0 dS m−1, and S2 = 2.0 dS m−1) on snap bean growth and yield. Our results indicate that S2 reduced 20% bean biomass production, 11% plant height, 13% root weight, and 23% AMF root colonization. However, microbial inoculations increased 26% bean yield over different salinity treatments. Maximum salinity stress (S2) increased 6% and 18% GRSP production than S1 and SC, respectively, indicating the relative advantage of abiotic stress on AMF’s role in soil. Dual inoculation (IT2) demonstrated a beneficial role on all physiological parameters, biomass production, and GRSP synthesis compared to single inoculation (IT1) treatment with all three salinity levels.

BACKGROUND: Chemical seed treatment is an established practice in agriculture to protect crops from soil-borne pathogens and pests. Arbuscular mycorrhizal fungi (AMF) benefit plants by extending soil exploration as well as water and nutrient uptake. The objective of this work was to analyze the effects of combinations of seed treatments with doses of inoculant containing Rhizoglomus intraradices on vegetative development, root colonization and nutrition of Phaseolus vulgaris plants and soil microbiota.RESULTS: Seed treatment benefited the vegetative development and nutrition of beans, with the treatments metalaxyl + fludioxonil + tiabendazole and pyraclostrobin + thiophanate methyl + fipronil standing out regarding the contents of nitrogen (N), phosphorus (P), iron (Fe) and zinc (Zn) of the aerial parts. Mycorrhizal inoculation linearly increased dehydrogenase activity, root biomass and total plant biomass, with increments reaching 27%. There was an interaction between seed treatment and inoculation dose for aboveground biomass and the contents of potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), manganese (Mn) and root colonization, with expressive results for the combination of the two highest doses of inoculant with metalaxyl + fludioxonil + tiabendazole or pyraclostrobin + methylthiophanate + fipronil in the seeds.CONCLUSION: Chemical seed treatment and mycorrhizal inoculation benefited bean plants and their nutritional status. The best combinations for the bean crop were metalaxyl + fludioxonil + tiabendazole with 41.4 mg of the inoculant per 100 seeds and pyraclostrobin + thiophanate methyl + fipronil with 62.1 mg of the inoculant per 100 seeds.
