Previously, algae were recognized as small prokaryotic and eukaryotic organisms found only in aquatic habitats. However, according to a recent paradigm shift, are considered ubiquitous organisms, occurring plant tissues well soil. Accumulating evidence suggests that represent member of the microbiome. New results indicate plants respond activate related downstream signaling pathways. Application has beneficial effects on health, such growth promotion disease control. Although accumulating secreted compounds cell wall components induce physiological structural changes protect against biotic abiotic stresses, knowledge underlying mechanisms algal determinants is limited. In this review, we discuss studies topic, highlight bioprotectant biostimulant roles new microbiome for crop improvement.

Microbes of the phytomicrobiome are associated with every plant tissue and, in combination form holobiont. Plants regulate composition and activity their bacterial community carefully. These microbes provide a wide range services benefits to plant; return, provides microbial reduced carbon other metabolites. Soils generally moist environment, rich which supports extensive soil communities. The rhizomicrobiome is great importance agriculture owing diversity root exudates cell debris that attract diverse unique patterns colonization. play key roles nutrient acquisition assimilation, improved texture, secreting modulating extracellular molecules such as hormones, secondary metabolites, antibiotics various signal compounds, all leading enhancement growth. compounds they secrete constitute valuable biostimulants pivotal stress responses. Research has demonstrated inoculating plants plant-growth promoting rhizobacteria (PGPR) or treating microbe-to-plant can be an effective strategy stimulate crop Furthermore, these strategies improve tolerance for abiotic stresses (egs. drought, heat, salinity) likely become more frequent climate change conditions continue develop. This discovery resulted multifunctional PGPR-based formulations commercial agriculture, minimize use synthetic fertilizers agrochemicals. review update about role PGPR from collection commercialization low-cost agricultural inputs.

Abstract Microbial composition and functions in the rhizosphere—an important microbial hotspot—are among most fascinating yet elusive topics ecology. We used 557 pairs of published 16S rDNA amplicon sequences from bulk soils rhizosphere different ecosystems around world to generalize bacterial characteristics with respect community diversity, composition, functions. The selects microorganisms soil function as a seed bank, reducing diversity. is enriched Bacteroidetes, Proteobacteria, other copiotrophs. Highly modular but unstable networks (common for r -strategists) reflect interactions adaptations dynamic conditions. Dormancy strategies are dominated by toxin–antitoxin systems, while sporulation common soils. Functional predictions showed that genes involved organic compound conversion, nitrogen fixation, denitrification were strongly (11–182%), nitrification depleted.

Modern intensive agricultural practices face numerous challenges that pose major threats to global food security. In order address the nutritional requirements of ever-increasing world population, chemical fertilizers and pesticides are applied on large scale increase crop production. However, injudicious use agrochemicals has resulted in environmental pollution leading public health hazards. Moreover, agriculture soils continuously losing their quality physical properties as well (imbalance nutrients) biological health. Plant-associated microbes with plant growth- promoting traits have enormous potential solve these play a crucial role enhancing biomass yield.
