“…Multiple metagenomic analyses have been carried out for investigating the genes related to plant growth-promoting traits of bacterial community from soil samples of oil field at Wietze ( Eze et al, 2021 ), from maize rhizosphere in the South Africa ( Molefe et al, 2021 ), associated with the root of sugar beet ( Tsurumaru et al, 2015 ), and the endophytes of Emilia sonchifolia (Linn.) DC ( Urumbil and Anilkumar 2021 ). These metagenomic analyses showed structural and functional diversity of plant microbiomes and allowed identification of genes and taxa putatively related to plant growth promotion.…”

The application of plant growth-promoting bacteria (PGPB) is vital for sustainable agriculture with continuous world population growth and an increase in soil salinity. Salinity is one of the severe abiotic stresses which lessens the productivity of agricultural lands. Plant growth-promoting bacteria are key players in solving this problem and can mitigate salinity stress. The highest of reported halotolerant Plant growth-promoting bacteria belonged to Firmicutes (approximately 50%), Proteobacteria (40%), and Actinobacteria (10%), respectively. The most dominant genera of halotolerant plant growth-promoting bacteria are Bacillus and Pseudomonas. Currently, the identification of new plant growth-promoting bacteria with special beneficial properties is increasingly needed. Moreover, for the effective use of plant growth-promoting bacteria in agriculture, the unknown molecular aspects of their function and interaction with plants must be defined. Omics and meta-omics studies can unreveal these unknown genes and pathways. However, more accurate omics studies need a detailed understanding of so far known molecular mechanisms of plant stress protection by plant growth-promoting bacteria. In this review, the molecular basis of salinity stress mitigation by plant growth-promoting bacteria is presented, the identified genes in the genomes of 20 halotolerant plant growth-promoting bacteria are assessed, and the prevalence of their involved genes is highlighted. The genes related to the synthesis of indole acetic acid (IAA) (70%), siderophores (60%), osmoprotectants (80%), chaperons (40%), 1-aminocyclopropane-1-carboxylate (ACC) deaminase (50%), and antioxidants (50%), phosphate solubilization (60%), and ion homeostasis (80%) were the most common detected genes in the genomes of evaluated halotolerant plant growth-promoting and salinity stress-alleviating bacteria. The most prevalent genes can be applied as candidates for designing molecular markers for screening of new halotolerant plant growth-promoting bacteria.

Plants select microorganisms from the surrounding bulk soil, which act as a reservoir of microbial diversity and enrich a rhizosphere microbiome that helps in growth and stress alleviation. Plants use organic compounds that are released through root exudates to shape the rhizosphere microbiome. These organic compounds are of various spectrums and technically gear the interplay between plants and the microbial world. Although plants naturally produce organic compounds that influence the microbial world, numerous efforts have been made to boost the efficiency of the microbiome through the addition of organic compounds. Despite further crucial investigations, synergistic effects from organic compounds and beneficial bacteria combinations have been reported. In this review, we examine the relationship between organic compounds and beneficial bacteria in determining plant growth and biotic and abiotic stress alleviation. We investigate the molecular mechanism and biochemical responses of bacteria to organic compounds, and we discuss the plant growth modifications and stress alleviation done with the help of beneficial bacteria. We then exhibit the synergistic effects of both components to highlight future research directions to dwell on how microbial engineering and metagenomic approaches could be utilized to enhance the use of beneficial microbes and organic compounds.

AimsVegetation type is one of the most important factors contributing to the changes in soil properties during the rehabilitation process in mining areas. There is still insu cient awareness of the relationship between soil properties and the function of soil microbes in the carbon and nitrogen cycles under different revegetation type in uences. MethodsSeven reclaimed vegetation plots which has been restored for over 30 years in the Pingshuo opencast coal mine, China were established (RP: Robinia pseudoacacia, UP: Ulmus pumila, LG: Larix gmelinii, PC: Populus simonii Carr., PT: Pinus tabuliformis, PA: Picea asperata, and PS: Pinus sylvestris). The soil properties and enzyme activity were detected, while the metagenomic approach was used to analyze the potential mechanisms of soil microorganisms work in carbon and nitrogen metabolism. ResultsTotal N was obviously highest in the PC habitat (2.347 ± 0.017%), followed by RP (2.188 ± 0.059 %). The major facilitator Superfamily COG0477 and dehydrogenase the COG2133 were signi cantly enriched in the PR habitat. The acetolactate synthase COG0028 was signi cantly enriched in RP, followed by LG and PC (P < 0.05). β-glucosidase (EC3.2.1.21) were dominated in soil microbial communities among 7 vegetation types, and signi cantly richer in RP and LG, followed by PC and PT (P < 0.05). GTs and GHswere signi cantly richer in UP and LG, respectively. ConclusionRobinia pseudoacacia and Larix gmelinii may be good species choice for improving the productivity and stability of the soil ecosystem in mining areas. Highlights• The revegetation species affect soil nutrient conditions and enzyme activities.• COG0477, COG2133 and COG0028 are abundant in R. pseudoacacia habits.• β-glucosidase genes dominate among all of the revegetation habits.• R. pseudoacacia and L. gmelinii are excellent species for reclamation in mining area.
