“…Most bacterial endophytes enter plants as rhizobacteria where they perform various plant growth-promoting functions ( Pimentel et al, 2011 ; Nair and Padmavathy, 2014 ). Gram-positive and gram-negative bacteria, including Achromobacter , Acinetobacter , Agrobacterium , Bacillus , Brevibacterium , Microbacterium , Pseudomonas , Xanthomonas , were identified from the endosphere ( Sun et al, 2013 ). Various plant growth-promoting bacterial endophytes have been isolated from plants as shown in Table 2 .…”

Globally, food security has become a critical concern due to the rise in human population and the current climate change crisis. Usage of conventional agrochemicals to maximize crop yields has resulted in the degradation of fertile soil, environmental pollution as well as human and agroecosystem health risks. Nanotechnology in agriculture is a fast-emerging and new area of research explored to improve crop productivity and nutrient-use efficiency using nano-sized agrochemicals at lower doses than conventional agrochemicals. Nanoparticles in agriculture are applied as nanofertilizers and/or nanopesticides. Positive results have been observed in terms of plant growth when using nano-based agricultural amendments. However, their continuous application may have adverse effects on plant-associated rhizospheric and endospheric microorganisms which often play a crucial role in plant growth, nutrient uptake, and disease prevention. While research shows that the application of nanoparticles has the potential to improve plant growth and yield, their effect on the diversity and function of plant-associated microorganisms remains under-explored. This review provides an overview of plant-associated microorganisms and their functions. Additionally, it highlights the response of plant-associated microorganisms to nanoparticle application and provides insight into areas of research required to promote sustainable and precision agricultural practices that incorporate nanofertilizers and nanopesticides.

“…P. cuspidatum produces polydatin, a glycosylated derivative of resveratrol. These endophytic bacteria isolated from P. cuspidatum have inhibitory activity against Aspergillus niger , Aspergillus fumigatus , B. subtilis , Gibberella fujikuroi , K. pneumoniae , and S. aureus [ 55 ]. From the roots and leaves of Radish ( Raphanus sativus L.) at Jinju, Korea, Proteobacteria , Bacillus, and Bacteroidetes spp.…”

“…Pusa Bold (DIR-50), a Ni-tolerant B. subtilis strain SJ-101 was isolated and identified. It was found that the strain SJ-101 produced indole acetic acid and solubilized inorganic phosphate [ 55 ]. Endophytic bacteria isolate from P. hydropiper contains plant growth promotion traits including indole acetic acid, siderophores, and phosphate-solubilization among others [ 156 ].…”

Bacterial endophytes reside within the tissues of living plant species without causing any harm or disease to their hosts. These endophytes can be isolated, identified, characterized, and used as biofertilizers. Moreover, bacterial endophytes increase the plants’ resistance against diseases, pests, and parasites, and are a promising source of pharmaceutically important bioactives. For instance, the production of antibiotics, auxins, biosurfactants, cytokinin’s, ethylene, enzymes, gibberellins, nitric oxide organic acids, osmolytes, and siderophores is accredited to the existence of various bacterial strains. Thus, this manuscript intends to review the sustainable applications of endophytic bacteria to promote the growth, development, and chemical integrity of medicinal and herbal plants, as well as their role in plant physiology. The study of the importance of bacterial endophytes in the suppression of diseases in medicinal and herbal plants is crucial and a promising area of future investigation.

Endophytic bacteria live in plant tissues which utilized in plant protection against phytopathogens. This study aims to investigate the diversity of endophytic bacteria from the leaves of traditional medicinal plants that has anti-phytopathogens properties. Isolation of endophytic bacteria was done by spread plate method. The bacteria were characterised by Gram staining and the 16S rRNA gene analysis. Further screening of anti-phytopathogen activity used disc diffusion method for Ralstonia solanacearum, Xanthomonas campestris, Fusarium oxysporum, and Sclerotium rolfsii. All togethers, sixteen isolates of endophytic bacteria from the leaves of eight medicinal plants species were obtained. Fourteen isolates had an anti-phytopathogen (with eight isolates against R. solanacearum, seven isolates against X. campestris, nine isolates against F. oxysporum, and five isolates against S. rolfsii). From the 14 isolates identified, phylum Firmicutes were dominant (64.3%), followed by Proteobacteria (28.6%), and Actinobacteria (7.1%). Phylum Firmicutes consists of Bacillus indicus (BJF1, TCF1, and MCF2), Bacillus pumilus (CAF4), Bacillus sp. (CAF1), Bacillus subtilis (AAF2, MCF1, CAF3, and MCF3); phylum Proteobacteria consists of Pantoea agglomerans (CAF2), Pantoea stewartii (AAF4), Pseudomonas oryzihabitans (AAF3), and Pseudomonas psychrotolerans (AAF1); and phylum Actinobacteria consists of Kocuria kristinae (CSF1).
