“…Biocontrol activity is not a peculiar measure for the initiation of resistance. As a result, other PGPF found in the rhizosphere soil do not possess antagonistic properties that induce resistance in plants against phytopathogenic diseases [ 21 , 22 ]. As a result, there are other features, unlike antagonism, that can carry out various roles in the resistance against phytopathogen invasion.…”

“…Various studies reported the following PGPF genera ( Gliocladium , Penicillium , Phoma , Phytophthora , Rhizoctonia , Talaromyces , Trichoderma ) to improve tomato [ 15 ], orange [ 10 ], apple [ 17 ], pear [ 18 ], cucumber [ 19 ], carrot [ 20 ], and other plants’ growth and further promote the plants’ innate immunity and the production of various necessary secondary metabolites by the plants. PGPF perform the following functions in plants: antagonistic or biocontrol potential by competing for space and nutrients [ 10 ], growth hormone production [ 21 ], mineral solubilization, mycoparasitic and saprophytic resistance, root colonization, and induced systemic resistance (ISR) in plants [ 22 ]. Aside from the above roles mentioned, PGPF suppress the invasion of phytopathogens on tomato plants as well as other crop plants, they contribute to the improvement of nutrients in the soil, and they produce 1-aminocyclopropane-1-carboxylate (ACC) deaminase and other phytohormones to reduce the production of ethylene in the plants [ 23 ].…”

The fungi species dwelling in the rhizosphere of crop plants, revealing functions that endeavor sustainability of the plants, are commonly referred to as ‘plant-growth-promoting fungi’ (PGPF). They are biotic inducers that provide benefits and carry out important functions in agricultural sustainability. The problem encountered in the agricultural system nowadays is how to meet population demand based on crop yield and protection without putting the environment and human and animal health at risk based on crop production. PGPF including Trichoderma spp., Gliocladium virens, Penicillium digitatum, Aspergillus flavus, Actinomucor elegans, Podospora bulbillosa, Arbuscular mycorrhizal fungi, etc., have proven their ecofriendly nature to ameliorate the production of crops by improving the growth of the shoots and roots of crop plants, the germination of seeds, the production of chlorophyll for photosynthesis, and the abundant production of crops. PGPF’s potential mode of action is as follows: the mineralization of the major and minor elements required to support plants’ growth and productivity. In addition, PGPF produce phytohormones, induced resistance, and defense-related enzymes to inhibit or eradicate the invasion of pathogenic microbes, in other words, to help the plants while encountering stress. This review portrays the potential of PGPF as an effective bioagent to facilitate and promote crop production, plant growth, resistance to disease invasion, and various abiotic stresses.

“…Other priming techniques such as osmopriming, hydropriming, halopriming and nutripriming, etc., also impart stress tolerance in plants; however, priming with biological agents is beneficial to a greater extent because it efficiently manages several seed‐ and soil‐borne diseases along with improving overall soil health 16‐18 .

Chemicals are extensively used in agriculture to increase crop production to meet the nutritional needs of an expanding world population. However, their injudicious application adversely affects soil's physical, chemical, and biological properties, subsequently posing a substantial threat to human health and global food security. Beneficial microorganisms improve plant health and productivity with minimal impact on the environment; however, their efficacy greatly relies on the application technique. Biopriming is an advantageous technique that involves the treatment of seeds with beneficial biological agents. It exhibits immense potential in improving the physiological functioning of seeds, thereby playing a pivotal role in their uniform germination and vigor. Biopriming mediated molecular and metabolic reprogramming imparts stress tolerance to plants, improves plant health, and enhances crop productivity. Besides, it is also associated with rehabilitating degraded land, improving soil fertility, health, and nutrient cycling. Although biopriming has vast applications in the agricultural system, its commercialization and utilization by farmers is still in their infancy. This review aims to critically analyze the recent studies based on biopriming‐mediated stress mitigation by alteration in physiological, metabolic, and molecular processes in plants. Additionally, considering the necessity of popularizing this technique, major challenges and prospects linked to the commercialization and utilization of this technique in agricultural systems have also been discussed.This article is protected by copyright.

“…However, the studies also showed that B. velezensis strains seemingly differ in their abilities to control certain rice diseases, which might be insufficient to meet the requirements of high efficiency and low-carbon in green rice production. The broad-spectrum B. velezensis strains with versatility in antagonistic, host immunity inducing, and plant-growth-promoting, are urgently needed to protect paddies from the attacks of an armada of diseases simultaneously ( Shasmita et al, 2022 ).…”

Biological control is an effective measure in the green control of rice diseases. To search for biocontrol agents with broad-spectrum and high efficiency against rice diseases, in this study, a strain of antagonistic bacterium BR-01 with strong inhibitory effect against various rice diseases was isolated from Bolbostemmatis Rhizoma by plate confrontation method. The strain was identified as Bacillus velezensis by morphological observation, physiological and biochemical identification, and molecular characterization by 16S rDNA and gyrB gene sequencing analysis. The confrontation test (dual culture) and Oxford cup assays demonstrated that B. velezensis BR-01 had strong antagonistic effects on Magnaporthe oryzae, Ustilaginoidea virens, Fusarium fujikuroi, Xanthomonas oryzae pv. Oryzicola, and Xanthomonas oryzae pv. oryzae, the major rice pathogens. The genes encoding antimicrobial peptides (ituA, ituD, bmyB, bmyC, srfAA, fenB, fenD, bacA, and bacD) were found in B. velezensis BR-01 by PCR amplification with specific primers. B. velezensis BR-01 could produce protease, cellulase, β-1,3-glucanase, chitinase, indoleacetic acid, siderophore, and 1-aminocyclopropane-1-carboxylate (ACC) deaminase, and might produce three lipopeptide antibiotics, surfactin, iturin, and fengycin based on Liquid chromatography–mass spectrometry (LC-MS) results. Furthermore, the plant assays showed that B. velezensis BR-01 had significant control effects on rice bacterial blight and bacterial leaf streak by pot experiments in greenhouse. In conclusion, B. velezensis BR-01 is a broad-spectrum antagonistic bacterium and has the potential as the ideal biocontrol agent in controlling multiple rice diseases with high efficiency.
