Rhizosphere microbiome: Engineering bacterial competitiveness for enhancing crop production

The Role of Secretion Systems, Effectors, and Secondary Metabolites of Beneficial Rhizobacteria in Interactions With Plants and Microbes

“…Much research has been conducted regarding PGPR, BCA, and RNB and many effectors are known and are not mentioned in this review. Despite the knowledge of those secreted molecules, their functionality in planta remains unclear (Bai et al, 2020;Kumar and Dubey, 2020;Zhou et al, 2020). The importance of the RNB secretion system in nodule formation and symbiosis between rhizobia and legumes is known; however, direct interactions of effectors and plant proteins and the specific processes regulated by the effectors are not understood.…”

Phosphate-Solubilizing Fungi and Alkaline Phosphatase Trigger the P Solubilization During the Co-composting of Sorghum Straw Residues With Burkina Faso Phosphate Rock

“…Although the difference in available P was not significant between the two treatments, this result further supports that the release of available P in BPR-enriched composts is sustained better by the addition of rhizosphere soil during composting. The rhizosphere which is the narrow zone in the soil near roots (Kumar and Dubey, 2020) provides various ecosystem services, including the cycling of nutrients (Adle, 2016), and it is an enormous reservoir of microbial community and small soil-inhabiting animals (Malla et al, 2018;Dubey et al, 2019). However, the functionality of this rhizosphere microbiome depends on several factors such as the intrinsic natural abundance of microbes in the environment which also relates to the soil physicochemical properties, the type of plant since the nature of the released secondary molecules triggering microbial activities FIGURE 3 | Distribution of phoD, phnX, and aphA genes involved in P mineralization.…”

Catalyzing Holistic Agriculture Innovation Through Industrial Biotechnology

“…245,246 This ability has led to the expectation that we can engineer microbiomes for a whole spectrum of AABs. [247][248][249][250] Agricultural production systems are very dependent on a diverse set of microbiomes that populate plant and animal production systems. Plant and soil microbiomes play essential roles in support of plant growth, cycling of carbon and other nutrients, and maintenance of healthy soils.…”

“…Plant and soil microbiomes play essential roles in support of plant growth, cycling of carbon and other nutrients, and maintenance of healthy soils. 249,[250][251][252][253] Although metagenomic sequencing reveals microbial identities and functional gene information, many uncharacterized interactions and many unculturable organisms remain to be undersood. 245,247,254 Therefore, metagenomics is only predictive of community functional potential and does not enable a mechanistic, predictable, and controllable understanding of the highly coupled processes within microbomes.…”
