“…EPB22 bacterial mixture treated banana plants stimulated the defensive enzymes, such as peroxidase (PO), polyphenol oxidase (PPO), and PAL, in addition to the phenolic substances, which reduced the BBTV incidence up to 80% [59]. Similar responses were also detected in the BBTV-infected banana plants [63], TSWV-infected S. lycopersicum plants [229], and Urdbean leaf crinkle virus (ULCV)-infected black gram [54].…”

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.

“…EPB22 resulted in the activation of peroxidase, polyphenol oxidase, and phenylalanine ammonia lyase (PAL), as well as the accumulation of phenolic compounds, which contributes to multiple decreases in BBTV incidence with a final efficiency of up to 80% [62]. Similar changes were observed in BBTV-infected banana [20], ULCV-infected black gram [45], and TSWV-infected tomato plants [91].…”

“…It should be noted that some strains are able to protect a broad spectrum of plant species, enabling the development of versatile biocontrol agents on the base of these strains. Thus, treatment of plants with P. fluorescens strain CHA0 induced resistance against TNV in tobacco [44] as well as against ULCV in black gram (Vigna mungo) [45] and Musa sp. [20].…”

Plant viruses are globally responsible for the significant crop losses of economically important plants. All common approaches are not able to eradicate viral infection. Many non-conventional strategies are currently used to control viral infection, but unfortunately, they are not always effective. Therefore, it is necessary to search for efficient and eco-friendly measures to prevent viral diseases. Since the genomic material of 90% higher plant viruses consists of single-stranded RNA, the best way to target the viral genome is to use ribonucleases (RNase), which can be effective against any viral disease of plants. Here, we show the importance of the search for endophytes with protease and RNase activity combined with the capacity to prime antiviral plant defense responses for their protection against viruses. This review discusses the possible mechanisms used to suppress a viral attack as well as the use of local endophytic bacteria for antiviral control in crops.

“…Increased activity of peroxidases has been elicited by fluorescent pseudomonads in plants such as rice [11], black gram [36], groundnut [37], sugarcane [38], chillies [35] cucumber [13] and mango [10]. Polyphenol oxidases (PPO) are enzymes which use molecular oxygen to catalyze the oxidation of monophenolic and ortho diphenolic compounds.…”

“…The present study revealed that the peroxidase (PO) and polyphenol oxidase (PPO) activity also increased significantly up to 3 days in all the treatments and there after declined. Similarly, soil and foliar application of P. fluorescens (Pf1) induced the accumulation of phenolics and enhanced the activities of peroxidase, phenylalanine ammonia lyase and polyphenol oxidase in black gram against Urdbean leaf crinkle virus (ULCV) in black gram [36]. Similarly, plants produce active oxygen species (AOS) such as superoxide anion (O 2 ), hydrogen peroxide (H 2 O 2 ) and hydroxyl radical (OH).…”

Rice blast caused by ascomycetes fungus Magnaporthe oryzae, is mostly considered the utmost significant disease of rice worldwide since its widespread dissemination and destructiveness under conducive conditions. Experiments were conducted in phylloplane of rice plants to study the induction of various defense enzymes and accumulation of phenol by three biocontrol agents viz., P. fluorescens talc (Pf1), liquid formulation with TNAU - Pf1 and Biocure - B under pot culture. The application of bioformulatons of P. flourescens triggered the activity of three defense related enzymes viz., peroxidase (PO), polyphenol oxidase (PPO) and phenylalanine ammonia lyase (PAL) and SOD were induced and the accumulation of phenol was also noticed in phylloplane rice plant upon challenge inoculation with Magnaporthe oryzae the causal agent for leaf blast disease in rice. The activities of defense enzymes reached a peak at three days after inoculation (DAI) with the pathogen. Native PAGE analysis revealed the expression of an additional isoforms of PO, PPO, SOD and catalase were observed in biocontrol agents treated seedlings due to induced systemic resistance (ISR) induction.
