“…These endogenous compounds present in plant tissues are considered to be signals to coordinate plant development (Kudo et al, 2010). This is consistent with previous reports that many Flavobacteriaceae produce auxin and play an important role in promoting plant growth (Elena et al, 2007;Kaul et al, 2018;Vukanti, 2020;Kalyanasundaram et al, 2021). Various phosphatases in the strain not only improve the phosphorus absorption capacity of plant, but also coordinate the transformation of insoluble, inorganic and organic forms of phosphorus into bioavailable forms of phosphate in the growing environment.…”

Green algae are photosynthetic organisms and play an important role in coastal environment. The microbial community on the surface of green algae has an effect on the health and nutrition of the host. However, few species of epiphytic microbiota have been reported to play a role in promoting the growth of algae. In this study, 16S rDNA sequencing was used to study the changes of microbial composition on the surface of Ulva fasciata at different growth stages. Some growth promoting bacteria were identified. The possible growth-promoting behavior of the strains were verified by co-culture of pure bacteria obtained from the surface of U. fasciata with its sterile host. Among the identified species, a new bacterial species, Hyunsoonleella sp. HU1-3 (belonging to the family Flavobacteriaceae) significantly promoted the growth of U. fasciata. The results also showed that there were many genes involved in the synthesis of growth hormone and cytokinin in the genome of Hyunsoonleella sp. HU1-3. This study identified the bacterium Hyunsoonleella sp. HU1-3 for the first time, in which this bacterium has strong growth-promoting effects on U. fasciata. Our findings not only provide insights on the establishment of the surface microbiota of U. fasciata, but also indicate that Hyunsoonleella sp. HU1-3 is one of the important species to promote the growth of U. fasciata.

“…Targeted manipulations of soil community composition are used to mitigate the negative environmental impact of agrochemicals and improve crop nutrient use efficiency, thereby reducing the need for some fertilizers, and leading to both enhanced crop yield and increased plant resilience to environmental stress [ 15 ].…”

“…In regards to food safety, research has focused on the role of microbes in reducing food contamination from heavy metals, agrochemicals, industrial and urban waste, as well as soil-borne pathogens. Beneficial microorganisms like PGPB/R and AMF are now used in agriculture to replenish the use of agrochemicals, minimize the negative impact on the environment, and increase the quantity, quality and safety of farm products with subsequent benefits on human health [ 15 , 93 , 105 ]. Contaminants can reach the soil by atmospheric deposition, waste disposal, industrial effluents and direct application, and afterwards, groundwater, streams and sea through soil washing [ 125 , 146 ].…”

“…Soils characterized by active microbes and close interactions between fauna and plants bolster efficient nutrient cycling, pathogen resistance and overall crop health, and enhance long-term ecosystem stability given the future global change conditions [ 12 ]. In particular, soil microbes are the main organisms that sustain plant biomass production and plant health [ 14 , 15 ]. Several studies have shown that both direct and indirect manipulation of plant root and soil microbial communities appear to be a propitious strategy to enhance food crop yield, its nutritional quality and safety with beneficial effects for human and environmental health [ 16 , 17 ].…”

Soil is one of the key elements for supporting life on Earth. It delivers multiple ecosystem services, which are provided by soil processes and functions performed by soil biodiversity. In particular, soil microbiome is one of the fundamental components in the sustainment of plant biomass production and plant health. Both targeted and untargeted management of soil microbial communities appear to be promising in the sustainable improvement of food crop yield, its nutritional quality and safety. –Omics approaches, which allow the assessment of microbial phylogenetic diversity and functional information, have increasingly been used in recent years to study changes in soil microbial diversity caused by agronomic practices and environmental factors. The application of these high-throughput technologies to the study of soil microbial diversity, plant health and the quality of derived raw materials will help strengthen the link between soil well-being, food quality, food safety and human health.

“…Edaphic factors such as pH, soil type, indigenous microflora, oxygen, nutrient, and light availability (Hacquard et al, 2015;Kaul et al, 2018) exert considerable impact on the developmental stage and physiological status of the host plant (Hacquard et al, 2015). A recent plant phytometer study with six plant species, across diverse edaphic conditions and land use gradient, indicates that indigenous soil microflora were the direct drivers of active bacterial communities (Vieira et al, 2020).…”

Modern agriculture faces several challenges due to climate change, limited resources, and land degradation. Plant-associated soil microbes harbor beneficial plant growth-promoting (PGP) traits that can be used to address some of these challenges. These microbes are often formulated as inoculants for many crops. However, inconsistent productivity can be a problem since the performance of individual inoculants/microbes vary with environmental conditions. Over the past decade, the ability to utilize Next Generation Sequencing (NGS) approaches with soil microbes has led to an explosion of information regarding plant associated microbiomes. Although this type of work has been predominantly sequence-based and often descriptive in nature, increasingly it is moving towards microbiome functionality. The synthetic microbial communities (SynCom) approach is an emerging technique that involves co-culturing multiple taxa under well-defined conditions to mimic the structure and function of a microbiome. The SynCom approach hopes to increase microbial community stability through synergistic interactions between its members. This review will focus on plant-soil-microbiome interactions and how they have the potential to improve crop production. Current approaches in the formulation of synthetic microbial communities will be discussed, and its practical application in agriculture will be considered.
