“…In general, beneficial bacteria such as Bacillaceae (Bacillus and Priestia strains) can improve plant growth and development. In accordance with the growth stimulatory effects of B. velezensis GA1 on tomato, similar growth stimulatory effects were reported when B. velezensis JB0319 was applied on lettuce under salt stress (Bai et al, 2023). Moreover, it has been shown that tomato, eggplant and pepper treated by B. subtilis NCD-2 have significantly enhanced the plant height and biomass.…”

Boosting plant immunity by priming agents can lower agrochemical dependency in plant production. Levan and levan‐derived oligosaccharides (LOS) act as priming agents against biotic stress in several crops. Additionally, beneficial microbes can promote plant growth and protect against fungal diseases. This study assessed possible synergistic effects caused by levan, LOS and five levan‐ and LOS‐metabolizing Bacillaceae (Bacillus and Priestia) strains in tomato and wheat. Leaf and seed defense priming assays were conducted in non‐soil (semi‐sterile substrate) and soil‐based systems, focusing on tomato‐Botrytis cinerea and wheat‐Magnaporthe oryzae Triticum (MoT) pathosystems. In the non‐soil system, seed defense priming with levan, the strains (especially Bacillus velezensis GA1), or their combination significantly promoted tomato growth and protection against B. cinerea. While no growth stimulatory effects were observed for wheat, disease protective effects were also observed in the wheat‐MoT pathosystem. When grown in soil and subjected to leaf defense priming, tomato plants co‐applied with levan and the bacterial strains showed increased resistance to B. cinerea compared with plants treated with levan or single strains, and these effects were synergistic in some cases. For seed defense priming in soil, more synergistic effects on disease tolerance were observed in a non‐fertilized soil as compared to a fertilized soil, suggesting that potential prebiotic effects of levan are more prominent in poor soils. The potential of using combinations of Bacilliaceae and levan in sustainable agriculture is discussed.

“…Several studies have documented that a single inoculation with beneficial bacteria or fungi can improve the health, growth, and production of vegetable crops [ 79 , 80 , 81 , 82 ]. Each species can present genetic determinants in its genome that involve different direct plant promotion mechanisms, such as the solubilization of phosphates and volatile organic compounds, production of siderophores (iron chelating agents), and synthesis of phytohormones (e.g., auxins, goberellins, and cytokinins) and ACC deaminase activity.…”

“…Recently, it was proposed that plant microbiome engineering may occur through host-mediated and multiple generations for microbiome selection [ 99 , 100 ]. Therefore, any change in the microbiome can be caused by a single inoculation with a strain [ 79 ]. In addition, the inoculation of a single strain can have multiple effects not only on the metabolism or physiology of the host but also on the associated microbiome and the rhizosphere, endosphere, or phyllosphere.…”

The growing human population has a greater demand for food; however, the care and preservation of nature as well as its resources must be considered when fulfilling this demand. An alternative employed in recent decades is the use and application of microbial inoculants, either individually or in consortium. The transplantation of rhizospheric microbiomes (rhizobiome) recently emerged as an additional proposal to protect crops from pathogens. In this review, rhizobiome transplantation was analyzed as an ecological alternative for increasing plant protection and crop production. The differences between single-strain/species inoculation and dual or consortium application were compared. Furthermore, the feasibility of the transplantation of other associated micro-communities, including phyllosphere and endosphere microbiomes, were evaluated. The current and future challenges surrounding rhizobiome transplantation were additionally discussed. In conclusion, rhizobiome transplantation emerges as an attractive alternative that goes beyond single/group inoculation of microbial agents; however, there is still a long way ahead before it can be applied in large-scale agriculture.

Salt stress has detrimental effects on wheat plants at several physiological, biochemical, and molecular levels. This stress leads to suppressed growth, reduced grain yield, and poor quality of harvested grains. However, two approaches have shown promise for improving wheat salt tolerance: using a synthetic strigolactone analog called GR24 and applying plant growth-promoting rhizobacteria (PGPR). GR24 plays a vital role in regulating plant growth and development and in defense against various stresses. Conversely, PGPR are beneficial bacteria that colonize the rhizosphere of plants and promote their growth through multiple mechanisms. In our study, we investigated the effects of salinity on the growth and yield traits of two different wheat cultivars and explored the combined role of PGPR and GR24 in mitigating the impact of salt stress. We created three different salinity levels using NaCl in pots (original, 5 dS m−1, and 10 dS m−1) and inoculated wheat seeds with a salt-tolerant Bacillus velezensis UTB96 strain. In addition, we applied 10 μM GR24 via foliar application during the pollination stage. Our observations showed that salt stress negatively affected wheat’s growth, yield, and phytochemical properties compared to the control. However, both single and combined applications of PGPR and GR24 mitigated the adverse effects of salinity. The combined treatment had a more substantial impact than either alone in inducing and improving biochemical and ionic characteristics. These included decreasing Na+ content in both leaves and roots, and EL, H2O2, and MDA content in leaves while increasing K+ content in both leaves and roots, growth and yield-related traits, RWC, chlorophyll pigments, total protein, soluble sugar, starch, proline, GB, and antioxidant enzyme activity (APX, POX, and CAT) of leaves. In conclusion, integrating PGPR and GR24 can efficiently induce salt tolerance and improve plant growth under stressed conditions. This combined approach has the potential for broad applicability in supporting plant growth in the presence of salt stress.
