“…Similarly, Estrada-Bonilla et al (2021) reported that the inoculation of PSB enhances the availability and use efficiency of P in the sugarcane-soil system. Bargaz et al (2021) recently reviewed how the co-application of PSB and P in soil could enhance the efficient utilization of P for sustainable cropping systems and ensure the judicious use of mineral nutrients.…”

“…It plays important roles in energy transfer, respiration, enzyme activation/inactivation, photosynthesis, and root elongation (Elhaissoufi et al, 2020). Moreover, P has also been known to play a vital role during biological nitrogen fixation (BNF) in legumes, since 20% of total plant P being allocated to nodules (Bargaz et al, 2021;Farssi et al, 2021). P also represents the main constituent of plants cell including nucleic acids, membrane phospholipids, etc.…”

“…(Vance et al, 2003). However, although P concentration in most soils is typically high, the available P in the soil solution is less than 10 µM, which is below the plant requirements (Bargaz et al, 2021). Thus, in the most agricultural soils, farmers use chemical P fertilizers to increase the available P levels (Ekardt, 2016).…”

“…However, the major parts of the applied P are likely to lose due to various biochemical processes related to P cycle including sorption, fixation, and immobilization (Penn and Camberato, 2019). On the another hand, at high concentration, P may cause significant environmental risk from leaching, runoff, and erosion (Bargaz et al, 2021). Therefore, there is a need for developing strategies that can improve P use efficiency by plants without having any risks on the environment.…”

Silicon- and Phosphate-Solubilizing Pseudomonas alkylphenolica PF9 Alleviate Low Phosphorus Availability Stress in Alfalfa (Medicago sativa L.)

et al. 2022

Low phosphorus (P) availability is a major limiting factor facing current agriculture in several agricultural areas. Many P fertilizers are applied to enhance P availability; however, the major part is likely to lose due to various processes related to P cycle. Silicon (Si) treatment and P-solubilizing bacteria inoculation have been emerged as a promising way to improve plant P nutrition. This study aimed to investigate the synergistic effects of Si treatment and Pseudomonas alkylphenolica PF9 strain inoculation on plant growth, P nutrition, acid phosphatase (APase) activity, oxidative stress markers, and antioxidant metabolism in the Moroccan alfalfa population Oued Lmalah (OL) under low P availability. Results revealed a significant reduction in dry biomass, plant height, leaf number, and area under low P conditions. P deficiency also altered P nutrition and chlorophyll (Chl) content. However, P-deficient alfalfa plants treated with Si or inoculated with PF9 strain displayed higher plant growth, Chl content, and remarkably the effect was much higher when Si was applied together with PF9 strain. Moreover, the simultaneous application of Si and PF9 strain to the P-deficient alfalfa plants improved APase activity and as a result, P contents in both the shoots and roots. Results also showed that the application of both the Si and PF9 counteracted the low P availability stress-induced oxidative damage by lowering the accumulation of reactive oxygen species (ROS), electrolyte leakage, and lipid peroxidation. This seems to be related to the ability of both the Si and PF9 strain to modulate both the enzymatic and non-enzymatic antioxidant molecules including superoxide dismutase activity, total polyphenols, flavonoids, and proline contents. Our findings suggest that the combined application of Si and P. alkylphenolica PF9 strain could be a promising way for improving growth of alfalfa under low-P availability.

“…This activity is relevant because a large amount of the P contributed by phosphate fertilizers loses efficiency due to different biochemical processes such as sorption, fixation, and immobilization, which in turn causes high rates of P application in crops. The inefficient use of phosphate fertilizers can modify the state of the nutrients in the soil, the availability for the absorption of the crops, and the microbial communities [4]. Finally, phosphate solubilizing bacteria can be an alternative for increasing the phosphorus available to plants [5,6].…”

Currently, agricultural systems are inadequate to meet the demand of the population, coupled with the constant degradation of natural resources. Therefore, it is necessary to explore alternatives to increase the productivity and quality of crops with minimal environmental impact. The use of plant growth-promoting bacteria can provide solutions to some agri-environmental problems and replace or minimize conventional agricultural practices. In this study, a Bacillus pumilus strain with plant growth-promoting properties was isolated from mature compost. In vitro, the ability of Bacillus pumilus to solubilize phosphate, inhibit the growth of phytopathogenic fungi, and its effect on the germination of tomato and lettuce seeds was evaluated. In vivo, its effect on stem thickness, height, and the number of leaves of tomato and lettuce seedlings was studied. The results show that, in vitro, Bacillus pumilus solubilizes phosphate, inhibits the growth of the fungus Fusarium oxysporum, and increases the germination percentage of tomato seeds. The results, in vivo, demonstrate that the bacteria increases the stem thickness of tomato seedlings, while, in lettuce, it increases the stem thickness and the number of leaves. The outcome implies that Bacillus pumilus has properties as a plant growth promoter and can be used as a promising inoculant to enhance the growth of tomato and lettuce seedlings.
