“…The results are well in agreement with our previous finding wherein a similar pattern of enzyme activity was observed irrespective of PGPF treatment and enzyme accumulation in pearl millet and cucumber [15,18]. The pattern of accumulation in enzyme activities may be attributed to the growth-promoting properties produced by the PGPF (like PGP traits), which exhibits the same set of defense-related activities during the host-pathogen interaction [16,19,51].…”

“…The obtained results were in corroboration with other studies, wherein antagonistic studies were regarded as the primary criteria to select the positive isolates for their evaluation against disease resistance during host-pathogen interaction in many crop plants [10,49,50]. Further, the antagonistic nature exhibited by PGPF is attributed to hyper parasitism, antibiosis (synthesis of antibiotics), production of lytic enzymes or competition for space and nutrients, which directly help in the management of invading pathogens [12,15,[49][50][51]. The qualitative analysis on the production of PGP traits confirmed that all the selected antagonistic isolates were positive for IAA, except NBP-44 and NBP-65, which were found negative for all the other traits evaluated.…”

“…The quantitative analysis of PGP traits was in line with the qualitative results. Similarly, Vinayarani et al [51] reported that rhizospheric fungi of turmeric were positive for PGP traits apart from possessing antagonistic activity against the invading pathogen and it is well attributed that the PGP-producing ability of the rhizosphere fungi is correlated to their non-pathogenic nature and disease suppression abilities [12,19].…”

“…Likewise, Jogaiah et al [16] have reported that the rhizosphere fungi that produced PGP traits were also non-pathogenic to host plants with very few offering pathogenicity. The antagonistic property of the rhizosphere fungi is asserted towards the offensive root colonization and defensive retention of rhizosphere niches that facilitate the production of siderophore, IAA and HCN, along with cell-wall degrading enzymes (cellulase and hemicellulase) that are reported to help in the improvement of plant growth and also induce resistance [13,14,49,[51][52][53].…”

In the current study, a total of 70 fungi were isolated from the rhizosphere soil of chilli collected from six different districts of south Karnataka, India. All the rhizospheric fungi were evaluated for its antagonistic nature against Colletotrichum capsici—the causal agent of anthracnose disease—and eight isolates were found positive. The antagonistic fungi were further characterized for the production of plant growth-promoting traits wherein five isolates were recorded positive for all the traits tested and were also positive for root colonization. All five plant growth-promoting fungi (PGPF) were subjected to molecular characterization for identification up to the species level and the accession numbers were obtained from NCBI. The five isolates, namely NBP-08, NBP-45, NBP-61, NBP-66 and NBP-67, were further experimented with on susceptible seeds to evaluate its efficacy on seed and plant growth parameters along with induction of resistance against the anthracnose disease. The evaluated PGPF offered significant enhancement in seed and plant growth parameters with maximum improvement observed in seeds treated with NBP-61. Among the PGPF isolates, NBP-61 showed the maximum protection of 78.75%, while all the other isolates also showed significant protection against anthracnose disease compared to untreated plants. The higher accumulation of lignin and callose deposition along with enhanced defense enzyme activities in the PGPF-treated challenge-inoculated seedlings authenticated the protection offered by PGPF. The study evidenced the immense ability of PGPF in eliciting disease protection and enhancement of plant growth in chilli, which may act as a possible substitute for harmful chemicals.

“…[ 50 ], Pseudomonas sp. [ 51 ], Trichoderma [ 52 , 53 ] and Mortierella [ 54 ] are applied as biofungicides and biofertilizers to agricultural soils to enhance crop growth. Therefore, changing the abundances of the genera of beneficial microorganisms in the rhizosphere may be one of the reasons why strain NCD-2 promotes the growth of crops.…”

Bacillus subtilis strain NCD-2 is a promising biocontrol agent for soil-borne plant diseases and shows potential for promoting the growth of some crops. The purposes of this study were to analyze the colonization ability of strain NCD-2 in different crops and reveal the plant growth promotion mechanism of strain NCD-2 by rhizosphere microbiome analysis. qRT-PCR was used to determine the populations of strain NCD-2, and microbial communities’ structures were analyzed through amplicon sequencing after application of strain NCD-2. Results demonstrated that strain NCD-2 had a good growth promotion effect on tomato, eggplant and pepper, and it was the most abundant in eggplant rhizosphere soil. There were significantly differences in the types of beneficial microorganisms recruited for different crops after application of strain NCD-2. PICRUSt analysis showed that the relative abundances of functional genes for amino acid transport and metabolism, coenzyme transport and metabolism, lipid transport and metabolism, inorganic ion transport and metabolism, and defense mechanisms were enriched in the rhizospheres of pepper and eggplant more than in the rhizospheres of cotton, tomato and maize after application of strain NCD-2. In summary, the colonization ability of strain NCD-2 for five plants was different. There were differences in microbial communities’ structure in rhizosphere of different plants after application of strain NCD-2. Based on the results obtained in this study, it was concluded that the growth promoting ability of strain NCD-2 were correlated with its colonization quantity and the microbial species it recruited.
