“…The endophyte Serendipita indica has the potential to enhance phosphorus uptake and plant growth by mobilizing inorganic phosphorus and stimulating phosphatase enzyme activ-ity [63,64]. Indeed, enhanced phosphorus levels have a significant impact on not just plant growth but also nodulation and biological nitrogen fixation [65,66]. Thus, the inoculation with R. tropici CIAT 899, either alone or with Serendipita indica or Rhizophagus irregularis, increased nitrogen content (Figure 4) compared with the control.…”

The overuse of chemical pesticides and fertilizers in crop farming has led to a decrease in crop quality and negative impacts on soil and the environment. It is crucial to adopt alternative strategies to maintain soil and environmental quality while enhancing crop growth and yield. To explore this, a study was conducted under greenhouse conditions to investigate the effect of Rhizobium tropici CIAT 899 alone, as well as in association with mycorrhizae (Rhizophagus irregularis) and endophytic fungus (Serendipita indica), on the growth, yield, and nutrient status of snap bean plants. At harvest, the rhizobial strain CIAT 899 demonstrated the highest effectiveness. It significantly increased the number of nodules in both Contender and Garrafal Enana varieties by 6.97% and 14.81%, respectively, compared with the control without inoculation. Furthermore, the results indicated that co-inoculation of Rhizobium and symbiotic fungi had positive effects on nitrogen content, phosphorus availability, and overall plant growth. Regardless of the variety, plants inoculated with R. tropici CIAT 899 and Serendipita indica exhibited the highest values for plant growth parameters. This combination resulted in 168% and 135% increases in root dry biomass, as well as 140% and 225% increases in the number of pods for Contender and Garrafal Enana, respectively, compared with the control at harvest. Additionally, this study highlights the potential benefits of combining R. tropici with either Serendipita indica or Rhizophagus irregularis in terms of nitrogen and phosphorus uptake. These symbiotic microorganisms demonstrated synergistic interactions with snap bean plants, leading to improved mineral nutrition and enhanced growth. Overall, these findings suggest that utilizing these symbiotic microorganisms can effectively enhance the mineral nutrition and growth of snap bean plants.

“…Therefore, the development of P assimilation may also be due to capacity regulation of signals sent by plants in relation to their P deficiency. Phosphorus is stored in fungal structures in the form of polyphosphates before being transmitted to the plant at the level of the arbuscular interface [10]. Moreover, phosphorus plays an important role in various metabolic processes in plants, such as protein synthesis, photosynthesis, cell division, respiration, energy storage and nutrient transport in plants.…”

Biofertilizers management for sustainable agriculture is a challenge to improve farmers ‘food security today and correct nutrient deficiencies (potassium, phosphorus and nitrogen) in plant. As biofertilizers, mycorrhizal symbiosis plays an important role in nutrient uptake and the productivity of plants. The aim of this study was the Rhizobium and mycorrhizal inoculations effect on plant growth and mineral nutrition of snap bean variety "Contender" in greenhouse condition. The experiment was a randomized block design with four treatments: a control non-inoculated, dual inoculation with Serendipita indica (S.indica) and Rhizobium tropici Ciat 899 strain (Ciat 899), dual inoculation with Rhizophagus irregularis (R. irregularis) and Ciat 899, and combined inoculation with R. irregularis, S.indica and Ciat 899 ; using eight replicates per treatment. Ciat 899 associated with S.indica or R. irregularis significantly increased plant growth parameters, and shoots and root phosphorus concentrations. It shows higher biomass production, pod number, nodule number and phosphorus content than plants inoculated with triple strains and non-mycorrhizal plants. Thus, the colonization rate exceeds 80%. The results of this study show that dual inoculation with Rhizobium and mycorrhizal fungi enhance significantly productivity in common bean.

“…Co-inoculation of A. chroococcum along with P. indica in wheat under zinc deficiency has been shown to result in higher root and shoot biomass [ 31 ], while in Artemesia annua , the co-inoculants demonstrated significant increases in plant growth, photosynthetic pigments, total soluble sugar, soluble proteins, and flavonoids content [ 32 ]. Additionally, P. indica and A. chroococcum have been reported to increase growth and productivity, as well as improving mineral nutrition in various crop plants [ 20 , 33 , 34 ]. However, reports studying the underlying mechanism as well as the effect of co-inoculation at molecular level are still limited.…”

The soil microbiome contributes to nutrient acquisition and plant adaptation to numerous biotic and abiotic stresses. Numerous studies have been conducted over the past decade showing that plants take up nutrients better when associated with fungi and additional beneficial bacteria that promote plant growth, but the mechanisms by which the plant host benefits from this tripartite association are not yet fully understood. In this article, we report on a synergistic interaction between rice (Oryza sativa), Piriformospora indica (an endophytic fungus colonizing the rice roots), and Azotobacter chroococcum strain W5, a free-living nitrogen-fixing bacterium. On the basis of mRNA expression analysis and enzymatic activity, we found that co-inoculation of plant roots with the fungus and the rhizobacterium leads to enhanced plant growth and improved nutrient uptake compared to inoculation with either of the two microbes individually. Proteome analysis of O. sativa further revealed that proteins involved in nitrogen and phosphorus metabolism are upregulated and improve nitrogen and phosphate uptake. Our results also show that A. chroococcum supports colonization of rice roots by P. indica, and consequentially, the plants are more resistant to biotic stress upon co-colonization. Our research provides detailed insights into the mechanisms by which microbial partners synergistically promote each other in the interaction while being associated with the host plant.
