“…Bacillus velezensis 5B6 could elicit ISR in pepper plants against cucumber mosaic virus through upregulation of pathogenicity‐related (PR) genes (Lee and Ryu ). Similarly, Guo et al () reported that B . velezensis Ba13 could show ISR in tomato against tomato yellow leaf curl virus by enhancing the expression of PR genes ( PR1 , PR2 , PR3 ) and defence‐related enzymes.…”

Bacillusspecies in soil as a natural resource for plant health and nutrition

The genus Bacillus is one of the predominant bacterial genera found in soil, and several species of this genus have been reported from diverse ecological niches. Endowed with tremendous genetic and metabolic diversity, Bacillus spp. serve multiple ecological functions in soil ecosystem from nutrient cycling to conferring stress tolerance to plants. Members of the genus Bacillus are known to have multiple beneficial traits which help the plants directly or indirectly through acquisition of nutrients, overall improvement in growth by production of phytohormones, protection from pathogens and other abiotic stressors. This functionally versatile genus is one of the most commercially exploited bacteria in the agro-biotechnology industry. Still its potential has not been realized sufficiently and requires an emphasis towards translating the relevant technologies from laboratory to land for the benefit of mankind.

“…Plant growth-promoting rhizobacteria (PGPR) may affect plant growth, development, and disease suppression by one or more direct or indirect mechanisms. Bacterial genera such as Bacillus and Pseudomonas have been extensively studied and utilized as biocontrol agents, biofertilizers, and also have been shown to trigger induced systemic resistance (ISR) [18][19][20][21][22][23][24]. In this review, we discuss the importance, functions, and effects of root-derived organic molecules secreted in the rhizosphere and their interactions with plant growth-promoting rhizobacteria (PGPR) for enhancing plant growth and biological control of plant pathogens.…”

The Interactions of Rhizodeposits with Plant Growth-Promoting Rhizobacteria in the Rhizosphere: A Review

2019

View full text Add to dashboard Cite

Rhizodeposits, root exudates, and root border cells are vital components of the rhizosphere that significantly affect root colonization capacity and multiplication of rhizosphere microbes, as well as secretion of organic bioactive compounds. The rhizosphere is an ecological niche, in which beneficial bacteria compete with other microbiota for organic carbon compounds and interact with plants through root colonization activity to the soil. Some of these root-colonizing beneficial rhizobacteria also colonize endophytically and multiply inside plant roots. In the rhizosphere, these components contribute to complex physiological processes, including cell growth, cell differentiation, and suppression of plant pathogenic microbes. Understanding how rhizodeposits, root exudates, and root border cells interact in the rhizosphere in the presence of rhizobacterial populations is necessary to decipher their synergistic role for the improvement of plant health. This review highlights the diversity of plant growth-promoting rhizobacteria (PGPR) genera, their functions, and the interactions with rhizodeposits in the rhizosphere.Agriculture 2019, 9, 142 2 of 13 in the rhizosphere [12,13], and these interactions that influence plant growth and crop yields [14] can be root-root, root-insect, and root-microbe interactions [15]. The role of the rhizosphere is pivotal for plant growth-promotion, nutrition, and crop quality [16] because of the importance of plant-microbe interactions in the rhizosphere carbon sequestration, nutrient cycling, and ecosystem functioning [17]. In addition, the rhizosphere is where plant roots communicate with beneficial rhizobacteria for energy and nutrition. Plant growth-promoting rhizobacteria (PGPR) may affect plant growth, development, and disease suppression by one or more direct or indirect mechanisms. Bacterial genera such as Bacillus and Pseudomonas have been extensively studied and utilized as biocontrol agents, biofertilizers, and also have been shown to trigger induced systemic resistance (ISR) [18][19][20][21][22][23][24]. In this review, we discuss the importance, functions, and effects of root-derived organic molecules secreted in the rhizosphere and their interactions with plant growth-promoting rhizobacteria (PGPR) for enhancing plant growth and biological control of plant pathogens. PGPR Diversity in the RhizosphereThe plant rhizosphere contains diverse rhizobacterial species with the potential to enhance plant growth and biological control activity. PGPR genera present in the rhizosphere include Agrobacterium,

“…Bacillus amyloliquefaciens has considerable potential for biological control of plant diseases (Chen et al 2014;Xiong et al 2015;Li et al 2017). This effect is the result of multiple mechanisms, including antagonism, competition, growth promotion and induction resistance (De Silva et al 2019;Guo et al 2019;Zhou et al 2020). Generally, the antagonistic activity of antimicrobial substances is the most direct and effective mechanism to inhibit the infection and growth of pathogens.…”

Aims: We aimed to purify an antimicrobial protein from Bacillus amyloliquefaciens FS6 culture supernatant, verify its antimicrobial activity against Fusarium solani and evaluate its biocontrol potential for ginseng root rot. Methods and Results: The antimicrobial protein was purified from FS6 culture supernatant using ammonium sulphate precipitation, anion exchange and gel chromatography. Based on mass spectrometry results, the purified protein was identified as an antimicrobial protein of the LCI family and was designated APC 2. The APC 2 recombinant protein expressed in Escherichia coli (BL21) significantly inhibited F. solani and decreased the infection and spread of F. solani in ginseng root. An overexpressing APC 2 strain FS6-APC 2 was constructed and shown to have enhanced antimicrobial activity compared to the wild-type strain FS6. Conclusions: The APC 2 protein shows strong antimicrobial activity against F. solani, reduces the incidence and severity of ginseng root rot caused by F. solani and exhibits a great biocontrol potential. Significance and Impact of the Study: This study reports the inhibitory activity of APC 2 protein (LCI family) against F. solani and its protective efficacy on ginseng root rot. These findings provide a scientific basis for future research on the biocontrol mechanism, as well as the development and application of FS6. 1996; Haas and D efago 2005; Nicolopoulou-Stamati et al. 2016). Biological control is environmentally friendly and less toxic to humans and animals. The application of biocontrol agents can minimize the progression towards pathogen resistance and represent the future of ginseng disease
