“…Durum (wheat) under non-stress conditions, reported an increase in plant length and weight, as well as the biovolume index, compared to inoculations of a single bacterial strain at a time. Similarly, Robles Montoya et al [84] reported that the use of a Bacillus consortium composed of B. paralicheniformis, B. subtilis, B. megaterium, and B. cabrialesii with wheat showed a significant increase (compared to un-inoculated seedlings) in the length of the aerial part of the plant, root length, total length, stem diameter, circumference, dry weight of the aerial part of the plant, and the biovolume index.…”

Plant-associated microorganisms play an important role in agricultural production. Although various studies have shown that single microorganisms can exert beneficial effects on plants, it is increasingly evident that when a microbial consortium—two or more interacting microorganisms—is involved, additive or synergistic results can be expected. This occurs, in part, due to the fact that multiple species can perform a variety of tasks in an ecosystem like the rhizosphere. Therefore, the beneficial mechanisms of plant growth stimulation (i.e., enhanced nutrient availability, phytohormone modulation, biocontrol, biotic and abiotic stress tolerance) exerted by different microbial players within the rhizosphere, such as plant-growth-promoting bacteria (PGPB) and fungi (such as Trichoderma and Mycorrhizae), are reviewed. In addition, their interaction and beneficial activity are highlighted when they act as part of a consortium, mainly as mixtures of different species of PGPB, PGPB–Mycorrhizae, and PGPB–Trichoderma, under normal and diverse stress conditions. Finally, we propose the expansion of the use of different microbial consortia, as well as an increase in research on different mixtures of microorganisms that facilitate the best and most consistent results in the field.

“…Bacillus megaterium TRQ8, B. cabrialesii TE3 T , and B. paralicheniformis TRQ65 were obtained from the microbial collection named Coleccion de Microorganismos Edáficos y Endófitos Nativos (COLMENA, , accessed on 11 February 2019) [ 8 , 59 ]. These strains were isolated from wheat crop rhizosphere in commercial fields located in the Yaqui Valley (27°00′ and 28°00′ N and 109°30′ and 110°37′ W) and have been previously characterized for their PGP traits (at a genomic, metabolic, and functional level) [ 8 , 11 , 12 , 15 , 16 , 32 , 33 , 34 , 60 ].…”

Bio-formulation technologies have a limited impact on agricultural productivity in developing countries, especially those based on plant growth-promoting rhizobacteria. Thus, calcium alginate microbeads were synthesized and used for the protection and delivery of three beneficial Bacillus strains for agricultural applications. The process of encapsulation had a high yield per gram for all bacteria and the microbeads protected the Bacillus strains, allowing their survival, after 12 months of storage at room temperature. Microbead analysis was carried out by observing the rate of swelling and biodegradation of the beads and the released-establishment of bacteria in the soil. These results showed that there is an increase of around 75% in bead swelling on average, which allows for larger pores, and the effective release and subsequent establishment of the bacteria in the soil. Biodegradation of microbeads in the soil was gradual: in the first week, they increased their weight (75%), which consistently results in the swelling ratio. The co-inoculation of the encapsulated strain TRQ8 with the other two encapsulated strains showed plant growth promotion. TRQ8 + TRQ65 and TRQ8 + TE3T bacteria showed increases in different biometric parameters of wheat plants, such as stem height, root length, dry weight, and chlorophyll content. Thus, here we demonstrated that the application of alginate microbeads containing the studied strains showed a positive effect on wheat plants.

“…Obregon, Sonora, México [43]. Wheat seeds were surface sterilized according to Robles Montoya et al (2020) [44] using 0.1% sodium hypochlorite (30 s), washed twice with sterilized distilled water (30 s), and incubated for five days at room temperature (25 • C) until germination. Subsequently, the seedlings were placed in sterilized and hermetic containers (washed with ethanol at 70% v/v and treatment with ultraviolet light for 1.5 h) with 130 g of an autoclaved substrate (30 min, 121 • C, 15 lbs in three 24 h intervals) (soil (40%): perlite (60%)) [45].…”

The Yaqui Valley, Mexico, has been historically considered as an experimental field for semiarid regions worldwide since temperature is an important constraint affecting durum wheat cultivation. Here, we studied the transcriptional and morphometrical response of durum wheat at an increased temperature (+2 °C) for deciphering molecular mechanisms involved in the thermal adaptation by this crop. The morphometrical assay showed a significant decrease in almost all the evaluated traits (shoot/root length, biovolume index, and dry/shoot weight) except in the dry root weight and the root:shoot ratio. At the transcriptional level, 283 differentially expressed genes (DEGs) were obtained (False Discovery Rate (FDR) ≤ 0.05 and |log2 fold change| ≥ 1.3). From these, functional annotation with MapMan4 and a gene ontology (GO) enrichment analysis with GOSeq were carried out to obtain 27 GO terms significantly enriched (overrepresented FDR ≤ 0.05). Overrepresented and functionally annotated genes belonged to ontologies associated with photosynthetic acclimation, respiration, changes in carbon balance, lipid biosynthesis, the regulation of reactive oxygen species, and the acceleration of physiological progression. These findings are the first insight into the regulation of the mechanism influenced by a temperature increase in durum wheat.
