Rhizospheric Fungi to Plant Growth Promotion: A Review

Abstract

The rhizosphere is the region that has direct influence from the roots. This is the place where most of the interactions between microorganisms and plants occur. Studies involving the ecology of microbial communities from the rhizosphere became more frequent after the first reports of biological interactions of microorganisms with plants that influence physically and chemically modify the soil surrounding. According to these hypotheses, the rhizosphere mycobiota provides the development of plants through various mechanisms, direct and indirect. Thus, the objective of this review was to explain the aspects that provide characterizing these microorganisms as beneficial to plants in view of their applicability to agro-ecosystems. Therefore, it is stated that rhizospheric fungi have the solubilization of phosphorus (P), assimilating this nutrient for plants, promoting growth through the production or stimulation of the production of growth regulators such as 3-indole acetic acid, and control of phytopathogenic agents such as other filamentous fungi, and also phytonemamatodes. Therefore, it is possible to observe the importance of the constant observance of the action of these microorganisms in terms of their ecological role due to the agro-ecosystem.

The role of plant-associated rhizobacteria in plant growth, biocontrol and abiotic stress management

“…Microflora found in the rhizosphere is dominated by bacteria, followed by fungi, protozoa, algae and actinomycetes (Kour et al, 2019;Poria et al, 2021). Various studies confirm the role of the microbial population in enhancing plant growth (da Silva et al, 2021;Fincheira et al, 2021). Kloepper et al, (1980) referred to such advantageous rhizobacteria as growth-enhancing rhizobacteria (PGPR) (Kloepper et al, 1980).…”

Influence and Role of Fungi, Bacteria, and Mixed Microbial Populations on Phosphorus Acquisition in Plants

“…Research findings underscore the pivotal role of AMF in facilitating plants' access to as much as 80% of inorganic phosphorus through a specialized "mycorrhizal phosphate uptake" (MPU) pathway, beside complementing the direct phosphorus uptake by the plants' own root epidermal cortical cells [57]. This symbiotic relationship not only augments nutrient absorption in plants, but also exerts profound effects on their growth and development [58][59][60][61]. The examination of the symbiotic interaction between the fungus Botrytis cinerea goes and the economic crop cotton has unveiled the consequential impact of Botrytis cinerea goes on cotton growth, fiber maturation, and yield, along with augmentations in the phosphorus contents in the roots, stems, and leaves of the plant.…”

Improving Soybean Production Using Light Supplementation at Field-Scale: A Case Study

“…3 potential (Orr et al, 2017;van Iersel, 2017;Nowicka et al, 2018;Kaiser et al, 2019;Batista-Silva et al, 2020;Singer et al, 2020). This can be done using different strategies including genetic techniques like the use of genetically modified organisms (Simkin et al, 2019), management of soil microbiota (Silva et al, 2021), or the addition of yield factors such as light (Goto, 2003;Gupta, 2017).…”
