“…Within a plant's physiological system, nitrogen-fixing endophytes help convert atmospheric dinitrogen gas (N 2 ) into nitrogen compounds that are accessible to plants, such as ammonium [46,47]. In a study using finger millet, two fungal endophytes, Aspergillus terreus, and Lecanicillium sp., and two bacterial endophytic isolates Pseudomonas bijieensis and Priestia megaterium were identified, which showed strong promotive effects on NPK contents in grains [48], further supporting the role of endophyte in nutrient enhancement in the host.…”

Plant phenotype is a complex entity largely controlled by the genotype and various environmental factors. Importantly, co-evolution has allowed plants to coexist with the biotic factors in their surroundings. Recently, plant endophytes as an external plant phenotype, forming part of the complex plethora of the plant microbial assemblage, have gained immense attention from plant scientists. Functionally, endophytes impact the plant in many ways, including increasing nutrient availability, enhancing the ability of plants to cope with both abiotic and biotic stress, and enhancing the accumulation of important plant secondary metabolites. The current state of research has been devoted to evaluating the phenotypic impacts of endophytes on host plants, including their direct influence on plant metabolite accumulation and stress response. However, there is a knowledge gap in how genetic factors influence the interaction of endophytes with host plants, pathogens, and other plant microbial communities, eventually controlling the extended microbial plant phenotype. This review will summarize how host genetic factors can impact the abundance and functional diversity of the endophytic microbial community, how endophytes influence host gene expression, and the host–endophyte–pathogen disease triangle. This information will provide novel insights into how breeders could specifically target the plant–endophyte extended phenotype for crop improvement.

“…The endophytes contribute to plant growth by solubilizing inorganic phosphorus which is insoluble and making it available to plants. This trait is common amongst many microbial communities' associate with various crop plants including wheat, rice, maize and legumes [2,3,24] . Several endophytes have been reported to have plant growth promoting properties such as members of the Burkholderia, Enterobacter, Halolamina, Pantoea, Pseudomonas, Citrobacter and Azotobacter [2,5,25] .…”

“…The practice of maintaining mineral nutrients in soil and plant systems is known as nutrient management. This strategy derives from integrated nutrient management (INM), which concentrates on the nutrients nitrogen (N), phosphorus (P), and potassium (K) by combining agrochemicals with efficient microorganisms (EM) [3,4] . Endophytes have been utilized to expand the range of soil fertility and mineralization or immobilization of various trace elements, such as N, P, K, Zn, Fe, Cu, Mg, and S, according to the principles of mineral nutrient management (MiNuM).…”

The diverse community of endophyte is a critical resource in enhancing plant growth. The endophytic bacteria belong to a larger group of microorganisms that have their life-cycle partly or entirely inside the plant and are located in intra and inter-cellular spaces or in the vascular tissue. Increasing nutritional content in staple crops either through agronomic biofortification or through conventional plant-breeding strategies continue to be a huge task for scientists around the globe. The microbial world of endophytes having the ability of nutrient mineralization has been proved a boon to mitigate hunger of the global population. This study aims to determine plant growth-promoting properties of total fourteen bacterial endophytes isolates from Wedelia urticifolia. WUR4 strain shows the best results out of all other isolates and shows the best plant growth-promoting activities. These includes potential to fix the nitrogen (+), solubilize phosphate (3.2 mm, 0.4636±0.0183 mg/ml), solubilize potassium (6.8 mm, 0.1438±0.0066 mg/ml) and siderophore production (zone +++, 69.9033±1.1509 SU). Our findings indicate that this isolate WUR4 have potential for future agricultural biotechnological applications through development for sustainable crop improvement and to formulate bio inoculant as well as can be used as biofertilizers.

“…Endophytic strains of Aspergillus terreus , Lecanicillium sp. Pseudomonas bijieensis , and Priestia megaterium have also been shown to induce improved Zinc concentration and NPK content in inoculated plants [ 114 ]. Fungal endophyte inoculation also helps to improve the growth and grain yield of plants growing under nutrient starvation conditions [ 115 ].…”

The negative impacts of climate change on native forest ecosystems have created challenging conditions for the sustainability of natural forest regeneration. These challenges arise primarily from abiotic stresses that affect the early stages of forest tree development. While there is extensive evidence on the diversity of juvenile microbial symbioses in agricultural and fruit crops, there is a notable lack of reports on native forest plants. This review aims to summarize the critical studies conducted on the diversity of juvenile plant–microbe interactions in forest plants and to highlight the main benefits of beneficial microorganisms in overcoming environmental stresses such as drought, high and low temperatures, metal(loid) toxicity, nutrient deficiency, and salinity. The reviewed studies have consistently demonstrated the positive effects of juvenile plant–microbiota interactions and have highlighted the potential beneficial attributes to improve plantlet development. In addition, this review discusses the beneficial attributes of managing juvenile plant–microbiota symbiosis in the context of native forest restoration, including its impact on plant responses to phytopathogens, promotion of nutrient uptake, facilitation of seedling adaptation, resource exchange through shared hyphal networks, stimulation of native soil microbial communities, and modulation of gene and protein expression to enhance adaptation to adverse environmental conditions.
