“…Another Actinomycete was reported to promote the growth of a halophyte using irrigation with seawater. Some biofilm-forming strains of Bacillus have been shown to enhance the growth of maize in saline conditions [82,83]. Another example is Bacillus subtilis (GB03), which was identified as a rhizosphere bacterium that stimulates growth of white clover under saline conditions [84], and which has since been renamed Bacillus amyloliquifaciens GB03 [85,86].…”

The salinization of soils is a growing agricultural concern worldwide. Irrigation practices, drought, and climate change are leading to elevated salinity levels in many regions, resulting in reduced crop yields. However, there is potential for a solution in the microbiome of halophytes, which are naturally salt-tolerant plants. These plants harbor a salt-tolerant microbiome in their rhizosphere (around roots) and endosphere (within plant tissue). These bacteria may play a significant role in conferring salt tolerance to the host plants. This leads to the possibility of transferring these beneficial bacteria, known as salt-tolerant plant-growth-promoting bacteria (ST-PGPB), to salt-sensitive plants, enabling them to grow in salt-affected areas to improve crop productivity. In this review, the background of salt-tolerant microbiomes is discussed and their potential use as ST-PGPB inocula is explored. We focus on two Gram-negative bacterial genera, Halomonas and Kushneria, which are commonly found in highly saline environments. These genera have been found to be associated with some halophytes, suggesting their potential for facilitating ST-PGPB activity. The study of salt-tolerant microbiomes and their use as PGPB holds promise for addressing the challenges posed by soil salinity in the context of efforts to improve crop growth in salt-affected areas.

“…Solubilization and translocation of ions such as phosphate and iron (by siderophores) to the plant. Phosphate and iron are critical to the plant but are often in low abundance or present only in inorganic forms that must be solubilized for use by plants ( [82,83], Table 1). The plants were inoculated with the bacteria and grown under NaCl-alkali regimes.…”

“…For instance, gyrB reveals highly similar bacterial community structure within Proteobacteria and Actinobacteria when compared with 16S, but it has merely 21.5% consistency in Firmicutes [34]. Therefore, amplicon sequence tools have been already developed for few genera that enable species-level resolution, such as rpoD amplicon methods for Pseudomonas and tuf-based methodology for Staphylococcus genus [29,37].…”

“…Another study combined pulse field gel electrophoresis with tuf identification to successfully genotype Bacillus isolates from various environments [27]. Altogether, these studies suggested tuf as a potential phylogenetic marker among Bacillus species, and this gene has moreover been used for similar purposes in other genera [29].…”

Bacillus species are ubiquitous in nature and have tremendous application potential in agriculture, medicine, and industry. However, the individual species of this genus vary widely in both ecological niches and functional phenotypes, which, hence, requires accurate classification of these bacteria when selecting them for specific purposes. Although analysis of the 16S gene has been widely used to disseminate the taxonomy of most bacterial species, this gene fails proper classification of Bacillus species. To circumvent this restriction, we designed novel primers and optimized them to allow exact species resolution of Bacillus species in both synthetic and natural communities using high-throughput amplicon sequencing. The primers designed for the tuf gene were not only specific for the Bacillus genus but also sufficiently discriminated species both in silico and in vitro in a mixture of 11 distinct Bacillus species. Investigating the primers using a natural soil sample, 13 dominant species were detected including Bacillus badius, Bacillus velezensis, and Bacillus mycoides as primary members, neither of which could be distinguished with 16S sequencing. In conclusion, a set of high-throughput primers were developed which allows unprecedented species-level identification of Bacillus species, including agriculturally important species.

“…Diverse members of Bacillus are involved in ecosystem functions including the degradation of soil organic matter, nitrogen cycle, carbon cycle, phosphorus solubilization, and eco-remediation of pollutants [ 8 ]. They also jointly function as plant growth promoters to alleviate abiotic stress or suppress plant pathogens [ 30 – 32 ]. In such scenarios, merely identifying individual taxa as Bacillus rather than individual species be insufficient for both basic science and potential microbiome engineering.…”
