“…Root dipping and foliar spray have been recommended for ohyamycin and blasticidin S against PVX, and tomato leaf curl may be effectively handled with DPB [149,150], and this antibiotic also helps in yield increase in S. lycopersicum. The bacterial bioagent Bacillus amyloliquefaciens (VB7) proficiently reduced the expression of GBNV disease symptom up to 84% through the transient expression of MAMP genes, triggered immune reaction, and decreased virus titer [151].…”

Plant viral diseases are major constraints causing significant yield losses worldwide in agricultural and horticultural crops. The commonly used methods cannot eliminate viral load in infected plants. Many unconventional methods are presently being employed to prevent viral infection; however, every time, these methods are not found promising. As a result, it is critical to identify the most promising and sustainable management strategies for economically important plant viral diseases. The genetic makeup of 90 percent of viral diseases constitutes a single-stranded RNA; the most promising way for management of any RNA viruses is through use ribonucleases. The scope of involving beneficial microbial organisms in the integrated management of viral diseases is of the utmost importance and is highly imperative. This review highlights the importance of prokaryotic plant growth-promoting rhizobacteria/endophytic bacteria, actinomycetes, and fungal organisms, as well as their possible mechanisms for suppressing viral infection in plants via cross-protection, ISR, and the accumulation of defensive enzymes, phenolic compounds, lipopeptides, protease, and RNase activity against plant virus infection.

“…Two flagellin genes and elongation factor of Bacillus amyloliquefaciens VB7 were involved in triggering the induction of plant defense against groundnut bud necrosis virus in tomato [249]. Secondary metabolites effectively suppressed symptoms in the indicator host plant (cowpea) up to 84%, compared with untreated control.…”

Plant growth promotion has been found associated with plants on the surface (epiphytic), inside (endophytic), or close to the plant roots (rhizospheric). Endophytic bacteria mainly have been researched for their beneficial activities in terms of nutrient availability, plant growth hormones, and control of soil‐borne and systemic pathogens. Molecular communications leading to these interactions between plants and endophytic bacteria are now being unrevealed using multidisciplinary approaches with advanced techniques such as metagenomics, metaproteomics, metatranscriptomics, metaproteogenomic, microRNAs, microarray, chips as well as the comparison of complete genome sequences. More than 400 genes in both the genomes of host plant and bacterial endophyte are up‐ or downregulated for the establishment of endophytism and plant growth‐promoting activity. The involvement of more than 20 genes for endophytism, about 50 genes for direct plant growth promotion, about 25 genes for biocontrol activity, and about 10 genes for mitigation of different stresses has been identified in various bacterial endophytes. This review summarizes the progress that has been made in recent years by these modern techniques and approaches.

“…While EIX/LeEIX2 recognition system is formed by an RLP-type PRR that recognize a fungal endo-xylanase, secreted by diverse fungi such as Trichoderma viridea and Botrytis cinerea [9][10][11][12]. In Arabidopsis and tomato exposure to flg22 confers resistance to the bacteria Pseudomonas sp, fungus Fusarium sp, and even against the virus GBNV [13][14][15]. While exposure to EIX-like endo-xylanase enhances resistance against B. cinerea and the virus TMV in tobacco [16].…”
