Insights into plant endophytic microbes and their exploration in agriculture have provided opportunities for sustainable plant health and food safety. Notable endophytic Bacillus species with plant growth-promoting traits have been documented; nevertheless, information on genome analysis of B. cereus associated with the sunflower in South Africa has not been studied. Therefore, we present whole-genome sequence of agriculturally important B. cereus strain T4S isolated from sunflower plants. The NextSeq Illumina sequencing yielded 7,255,762 bp sequence reads, 151 bp average read length, 5,945,881 bp genome size, 56 tRNA, 63 rRNA, and G + C content of 34.8%. The phylogeny analysis of strain T4S was similar to B. cereus NJ-W. Secondary metabolites, such as petrobactin, bacillibactin, bacitracin, molybdenum factor, zwittermicin, and fengycin underlining bacterial biocontrol efficacy against phytopathogens were found in the T4S genome. The predicted novel genes in the bacterial genome mediating the complex metabolic pathways can provide a genetic basis in understanding endosphere biology and their multiple functions thereof in crop improvement. Interestingly, seed and root inoculation with strain T4S contributed to sunflower yield under greenhouse experiments. Hence, the detection of notable genes specific for plant growth promotion as validated under in vitro screening, promisingly, suggests the relevance of strain T4S in agricultural biotechnology.

The rhizosphere microbiota contributes immensely to nutrient sequestration, productivity and plant growth. Several studies have suggested that environmental factors and high nutrient composition of plant’s rhizosphere influence the structural diversity of proximal microorganisms. To verify this assertion, we compare the functional diversity of bacteria in maize rhizosphere and bulk soils using shotgun metagenomics and assess the influence of measured environmental variables on bacterial diversity. Our study showed that the bacterial community associated with each sampling site was distinct, with high community members shared among the samples. The bacterial community was dominated by Proteobacteria, Actinobacteria, Acidobacteria, Gemmatimonadetes, Bacteroidetes and Verrucomicrobia. In comparison, genera such as Gemmatimonas, Streptomyces, Conexibacter, Burkholderia, Bacillus, Gemmata, Mesorhizobium, Pseudomonas and Micromonospora were significantly (p ≤ 0.05) high in the rhizosphere soils compared to bulk soils. Diversity indices showed that the bacterial composition was significantly different across the sites. The forward selection of environmental factors predicted N-NO3 (p = 0.019) as the most influential factor controlling the variation in the bacterial community structure, while other factors such as pH (p = 1.00) and sulfate (p = 0.50) contributed insignificantly to the community structure of bacteria. Functional assessment of the sampling sites, considering important pathways viz. nitrogen metabolism, phosphorus metabolism, stress responses, and iron acquisition and metabolism could be represented as Ls > Rs > Rc > Lc. This revealed that functional hits are higher in the rhizosphere soil than their controls. Taken together, inference from this study shows that the sampling sites are hotspots for biotechnologically important microorganisms.

The genus Pseudomonas contains a variety of genomic robust strains and species, well known for their beneficial use in a variety of applications, hence the vast amount of research done on this organism to date. We report here the draft genome sequence of an anti-Fusarium rhizospheric Pseudomonas fulva HARBPS9.1 strain from South Africa. This genome analysis identified clusters of genes responsible for the synthesis of pyoverdin and rhizomide in HARBPS9.1; these compounds should confer a competitive advantage on the pseudomonad.

Plant rhizobiomes are responsible for major soil processes in the immediate plant environment, but our knowledge of the linkage between below-ground microbiota diversity and plant health is limited. We studied the bacterial and archaeal communities of sunflower rhizosphere organisms by comparing the composition of these communities to bulk soils at three farms in the North West province of South Africa. We evaluated and described a plethora of bacterial and archaeal taxa.

Many strains from the Bacillus thuringiensis spp. are known for their genomic robustness and antimicrobial potentials. As a result, the quest for their biotechnological applications especially in the agroindustry (e.g. as biopesticides) has increased over the years. This study documents the genome sequencing and probing of a Fusarium antagonist (B. thuringiensis strain - MORWBS1.1) with possible biopesticidal metabolite producing capacity from South Africa. Based on in vitro evaluation and in silico antiSMASH investigation, B. thuringiensis strain - MORWBS1.1 exhibited distinctive genomic properties that could be further exploited.

The northwest (NW) province of South Africa is a semi-arid area, often disturbed by soil extremes such as drought and intense temperature. However, many functions possessed by the rhizosphere microbiome are still required, especially those inhabiting arid and semi-arid soils. This study involves a metagenomic comparison of the major metabolic attributes of two maize rhizosphere soils and their surrounding soils. Here, we hypothesized that there is a considerable difference between the functional diversity of maize rhizosphere and bulk soils and that the rhizosphere soil has distinct functional traits of agricultural importance. A high-throughput sequencing approach was used to assess the metabolic profile of rhizosphere soil microbiota of maize collected from the Gauteng and NW provinces of South Africa. The relative abundance of 13 functional hit categories was significantly different between the sampling sites. The diversity indices showed a considerable difference between the rhizosphere and surrounding soils. The difference in the chemical properties of the sampling sites was responsible for the variation in the microbial functional composition. Nevertheless, the presence of a high relative abundance of functional categories with unknown functions in SEED subsystem-2 coupled with the large number of functional hits conferring a response to soil stressors viz. oxidative stress, heat shock, osmotic stress, and cold shock noticed in the rhizosphere samples may indicate the presence of novel genes at the sampling sites. Exploring the plant growth-promoting traits of microorganisms present at these sites could eliminate the constraint posed by soil stressors on sustainable agriculture.

The abundance of nutrient accumulation in rhizosphere soils has placed the rhizosphere as an “epicenter” of bacterial concentrations. Nonetheless, over the years, little attention has been given to bacterial inoculants and soil-like substrates. The reason is that many farmers and experiments have focused on chemical fertilizers as an approach to improve plant growth and yield. Therefore, we focused on assessing the application of rhizosphere soil and its associated bacteria for biotechnological applications. This review has been structured into major subunits: rhizosphere soil as a treasure trove for bacterial community concentration, biodegradation of lignocellulose for biofuel production, rhizosphere soil and its bacteria as soil amendments, and the role of rhizosphere soil and its bacteria for bioremediation and biofiltration. Hence, the efficient use of rhizosphere soil and its bacteria in an environmentally friendly way can contribute to healthy and sustainable environments.

In recent times, diverse agriculturally important endophytic bacteria colonizing plant endosphere have been identified. Harnessing the potential of Bacillus species from sunflower could reveal their biotechnological and agricultural importance. Here, we present genomic insights into B. cereus T4S isolated from sunflower sourced from Lichtenburg, South Africa. Genome analysis revealed a sequence read count of 7 255 762, a genome size of 5 945 881 bp, and G + C content of 34.8%. The genome contains various protein-coding genes involved in various metabolic pathways. The detection of genes involved in the metabolism of organic substrates and chemotaxis could enhance plant-microbe interactions in the synthesis of biological products with biotechnological and agricultural importance.

The characterization of microbial functional diversity proffers the opportunity to understand and manipulate them in various agricultural and biotechnological processes. This study analyzed the functional diversity and metabolic potentials of microbial communities in the rhizosphere of a former grassland and an intensively cultivated land using a shotgun metagenomic approach. We assumed that functional diversity will vary between the two maize fields and that each soil has an active metabolic profile that differentiates it from the other. Metagenomic DNA was extracted from the rhizosphere, and bulk soil samples from maize fields and sequencing was performed using the shotgun method. The results showed that 14 functional categories were dominant in the former grassland rhizosphere, while 12 functions predominated the intensively cultivated land. In the subsystems at level 2, potassium metabolism was the most abundant functional category with the highest relative abundance of 21.32% observed in GZ3. No significant difference was observed in the alpha diversity studies between the two fields, the Kruskal-Wallis test also revealed an insignificant difference (p = 0.99) in the diversity levels of samples, while 0.51 and 0.01 were obtained as the R- and p-values, respectively from the analysis of similarity (ANOSIM) performed. Nitrate nitrogen (N-NO3) was the most influential physicochemical parameter, with a p-value of 0.01 and a contribution % of 81.7%. Furthermore, the high abundance of unknown functions explains that the maize microbiome is still underexplored. Identifying the microbial communities with these functions will help in modeling them to harvest their unique functional benefits for agricultural productivity enhancement.

BACKGROUND The geographical diversification in chemical, biological and physical properties of plant's biosphere instigates heterogenicity in the proliferation of important soil microbiome. Controlling functions and structure of plant rhizosphere due to better understanding and prediction of plant's immediate environment will help assess plant‐microbe interplay, improve the productivity of plant ecosystems and improve plant response to adverse soil conditions. Here we characterized functional genes of the microbial community of maize rhizosphere using a culture‐independent method. RESULTS Our metadata showed microbial genes involved in nitrogen fixation, phosphate solubilization, quorum sensing molecules, trehalose, siderophore production, phenazine biosynthesis protein, daunorubicin resistance, acetoin, 1‐aminocyclopropane‐1‐carboxylate (ACC) deaminase, 4‐hydroxybenzoate, disease control and stress‐reducing genes (superoxidase dismutase, catalase, peroxidase etc.). Beta‐diversity showed that there is a high significant difference between most of the genes mined from rhizosphere soil samples and surrounding soils. CONCLUSION The high relative abundance of stress‐reducing genes mined from this study showed that the sampling sites harbor not only important plant‐beneficial organisms but also a hotspot for developing bio‐fertilizers. Nevertheless, since most of these organisms are unculturable, mapping‐out cultivation strategies for their growth could make them readily available as bio‐inoculants and possible biotechnological applications in the future.

Microorganisms that display unique biotechnological characteristics are usually selected for industrial applications. Bacillus cereus NWUAB01 was isolated from a mining soil and its heavy metal resistance was determined on Luria–Bertani agar. The biosurfactant production was determined by screening methods such as drop collapse, emulsification and surface tension measurement. The biosurfactant produced was evaluated for metal removal (100 mg/L of each metal) from contaminated soil. The genome of the organism was sequenced using Illumina Miseq platform. Strain NWUAB01 tolerated 200 mg/L of Cd and Cr, and was also tolerant to 1000 mg/L of Pb. The biosurfactant was characterised as a lipopeptide with a metal-complexing property. The biosurfactant had a surface tension of 39.5 mN/m with metal removal efficiency of 69%, 54% and 43% for Pb, Cd and Cr respectively. The genome revealed genes responsible for metal transport/resistance and biosynthetic gene clusters involved in the synthesis of various secondary metabolites. Putative genes for transport/resistance to cadmium, chromium, copper, arsenic, lead and zinc were present in the genome. Genes responsible for biopolymer synthesis were also present in the genome. This study highlights biosurfactant production and heavy metal removal of strain NWUAB01 that can be harnessed for biotechnological applications.

Arid and semi-arid soils are characterized by nutrient deficiency and water scarcity, declining soil quality and climate regimes that are unfavorable for crop production. These environments are also affected by other inherent abiotic and biotic factors that affect the structure and function of these ecosystems. Numerous factors influence nutrient availability, plant productivity in an arid and semi-arid environment. One influential factor is the soil rhizospheric microbial community, which is an integral part of the terrestrial ecosystem. With climate change already affecting crop yield in drylands, the potential role of these organisms in land restoration for enhancing plant productivity needs to be exploited. Maximizing the rhizospheric microbial functions in these agroecosystems is essential in the reclamation of arid and semi-arid lands for optimum productivity in a wide range of environmental perturbations. In this review, we present the applications of rhizospheric plant growth-promoting (PGP) archaea and bacteria in the solubilization of nutrients, production of growth regulators, carbon sequestration, competitive exclusions of pathogens, and remediation of arid and semi-arid soils.

The diversity of plant-associated microbes is enormous and complex. These microbiomes are structured and form complex interconnected microbial networks that are important in plant health and ecosystem functioning. Understanding the composition of the microbiome and their core function is important in unraveling their networking strategies and their potential influence on plant performance. The network is altered by the host plant species, which in turn influence the microbial interaction dynamics and co-evolution. We discuss the plant microbiome and the complex interplay among microbes and between their host plants. We provide an overview of how plant performance is influenced by the microbiome diversity and function.

This study compares, for the first time, the diversity and community structure of the endophytic archaea and fungi inhabiting the roots of maize plant cultivated using two different fertilizer regimes and the control field via shotgun metagenomics. This was used to verify our hypothesis that organic farming positively influences the diversity, beneficial effects, and abundance of plant endophytic communities as compared with conventional farming. Total DNA extraction was carried out using the roots of maize plants cultivated with organic fertilizer (FK), inorganic fertilizer (NK), and without any fertilizer (CK) at different farming sites in an experimental field and sequenced using shotgun metagenomics. In all, 3 archaea phyla, namely, Crenarchaeota, Euryarchaeota, and Thaumarchaeota, and 2 fungi phyla, namely, Ascomycota and Basidiomycota, were identified in the samples with higher abundance in samples from the FK site. Our diversity results revealed that the abundance of endophytic archaea and fungi species across the farming sites are in the order NK < CK < FK. The results indicate that organic farming enhances the abundance of endophytic archaea and fungi which might be a boost to sustainable agricultural practices. Furthermore, some new genera of endophytic archaea and fungi were identified from the maize roots. Future studies into how these novel endophytes can be cultured are important in a bid to explore their functions in sustainable agriculture as well as identify their biotechnological importance.

This study investigated the diversity, structure and nutrient pathways of the root-associated bacterial endophytes of maize plant cultivated using different fertilizers to verify the claim that inorganic fertilizers have some toxic effects on plant microbiome and not are ecofriendly. Whole DNA was extracted from the roots of maize plants cultivated with organic fertilizer, inorganic fertilizer and maize planted without any fertilizer at different planting sites in an experimental field and sequenced using shotgun metagenomics. Our results using the Subsystem database revealed a total of 28 phyla and different nutrient pathways in all the samples. The major phyla observed were Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria, Acidobacteria, Chloroflexi, Verrucomicrobia, Tenericutes, Planctomycetes, Cyanobacteria, and Chlorobi. Bacteroidetes dominated maize from organic fertilizer sites, Firmicutes dominated the no fertilizers site while Proteobacteria dominated Inorganic fertilizer. The diversity analysis showed that the abundance of endophytic bacteria in all the sites is in the order organic fertilizer (FK) > no fertilizer (CK) > inorganic fertilizer (NK). Furthermore, the major nutrient cycling pathways identified are linked with nitrogen and phosphorus metabolism which were higher in FK samples. Going by the results obtained, this study suggests that organic fertilizer could be a boost to sustainable agricultural practices and should be encouraged. Also, a lot of novel endophytic bacteria groups were identified in maize. Mapping out strategies to isolate and purify this novel endophytic bacteria could help in promoting sustainable agriculture alongside biotechnological applications in future.
