“…Chemical fungicides are widely used to control this disease, as no resistance resources have yet been discovered in available rice germplasm. Moreover, the species complex of R. solani is composed of various 14 anastomosis groups (AGs; AG1-13 and AG-B1), having wide genetic diversity, broad host compatibility, and ability to survive from one crop season to the next by forming dormant sclerotia made disease control even more difficult ( Patil and Solanki, 2016 ; Abbas et al, 2021 ). Furthermore, agriculture confronts enormous challenges in providing enough food in a sustainable manner for an ever-increasing worldwide population while simultaneously dealing with unpredictable global environmental changes.…”

Trichoderma spp. Genes Involved in the Biocontrol Activity Against Rhizoctonia solani

Rhizoctonia solani is a pathogen that causes considerable harm to plants worldwide. In the absence of hosts, R. solani survives in the soil by forming sclerotia, and management methods, such as cultivar breeding, crop rotations, and fungicide sprays, are insufficient and/or inefficient in controlling R. solani. One of the most challenging problems facing agriculture in the twenty-first century besides with the impact of global warming. Environmentally friendly techniques of crop production and improved agricultural practices are essential for long-term food security. Trichoderma spp. could serve as an excellent example of a model fungus to enhance crop productivity in a sustainable way. Among biocontrol mechanisms, mycoparasitism, competition, and antibiosis are the fundamental mechanisms by which Trichoderma spp. defend against R. solani, thereby preventing or obstructing its proliferation. Additionally, Trichoderma spp. induce a mixed induced systemic resistance (ISR) or systemic acquired resistance (SAR) in plants against R. solani, known as Trichoderma-ISR. Stimulation of every biocontrol mechanism involves Trichoderma spp. genes responsible for encoding secondary metabolites, siderophores, signaling molecules, enzymes for cell wall degradation, and plant growth regulators. Rhizoctonia solani biological control through genes of Trichoderma spp. is summarized in this paper. It also gives information on the Trichoderma-ISR in plants against R. solani. Nonetheless, fast-paced current research on Trichoderma spp. is required to properly utilize their true potential against diseases caused by R. solani.

“…R. solani attacks members of Poaceae , Rubiaceae , Fabaceae , Solanaceae , Moraceae , Malvaceae , Linaceae , Araceae , and Amaranthaceae families. Disease symptoms on different hosts are stem rot and canker, hypocotyl rot, black scurf, pod rot, blights, root rot, crown rot, pre, and post-emergence damping-off ( Patil and Solanki, 2016 ). Among the legumes, soybean ( Glycine max ) is affected by R. solani , which causes aerial and underground diseases.…”

“…In contrast, biochemical and molecular-based approaches detect and diagnose R. solani efficiently due to their high sensitivity and specificity. In recent years, next-generation sequencing (NGS) has been used for detecting and diagnosing R. solani ( Das et al, 2016 ; Patil and Solanki, 2016 ). With new knowledge of detecting and diagnosing R. solani , the dissemination and spread of infection of R. solani will be controlled, and consequently, the economy of the farming community will be improved ( Das et al, 2016 ; Patil and Solanki, 2016 ).…”

Global distribution, traditional and modern detection, diagnostic, and management approaches of Rhizoctonia solani associated with legume crops

Sustainable development relies heavily on a food system that is both safe and secure. Several approaches may lead to sustainability and food safety. An increase in the cultivation of legume crops is one of the approaches for enhancing agricultural viability and ensuring adequate food supply. Legumes may increase daily intake of fiber, folate, and protein as substitutes for meat and dairy. They are also crucial in various intercropping systems worldwide. However, legume production has been hampered by Rhizoctonia solani due to its destructive lifestyle. R. solani causes blights, damping off, and rotting diseases in legume crops. Our knowledge of the global distribution of R. solani associated with legume crops (alfalfa, soybean, chickpea, pea, lentil, common bean, and peanut), detection, diagnosis, and management of legume crops diseases caused by R. solani is limited. Traditional approaches rely on the incubation of R. solani, visual examination of symptoms on host legume crops, and microscopy identification. However, these approaches are time-consuming, require technical expertise, fail to detect a minimal amount of inoculum, and are unreliable. Biochemical and molecular-based approaches have been used with great success recently because of their excellent sensitivity and specificity. Along with conventional PCR, nested PCR, multiplex PCR, real-time PCR, magnetic-capture hybridization PCR, and loop-mediated isothermal amplification have been widely used to detect and diagnose R. solani. In the future, Next-generation sequencing will likely be used to a greater extent to detect R. solani. This review outlines global distribution, survival, infection and disease cycle, traditional, biochemical, molecular, and next-generation sequencing detection and diagnostic approaches, and an overview of the resistant resources and other management strategies to cope with R. solani.

“…The plant rhizosphere contains beneficial and pathogenic microbes competing for nutrients and space ( Raaijmakers et al, 2009 ; Adesemoye et al, 2009 ; Beans, 2017 ; Li et al, 2021 ). Tomato root rot caused by sclerotia forming fungus Rhizoctonia solani , is a highly destructive disease that severely affects crop development and yield ( Patil and Solanki, 2016b ). To control R. solani , chemical fungicides must be applied, creating many environmental problems ( Le Cointe et al, 2016 ).…”

Microbial interactions with plant roots play an imperial role in tomato plant growth and defense against the Rhizoctonia solani. This study performed a field experiment with two antagonistic bacteria (Pseudomonas and Bacillus) inoculated in healthy and Rhizoctonia solani treated soil in tomato rhizosphere to understand the metabolic pattern and microbial function during plant disease suppression. In the present study, we assessed soil and microbial enzymes, bacterial and fungal cell forming unit (CFU), and carbon utilization profiling through Bio-Eco plates of rhizoplane samples. Antagonist bacteria and pathogen interaction significantly (p < 0.05) influenced the bacterial count, soil enzymes (chitinase and glucanase), and bacterial function (siderophore and chitinase production). These results indicated that these variables had an imperial role in disease suppression during plant development. Furthermore, the metabolic profiling showed that carbon source utilization enhanced under fruit development and ripening stages. These results suggested that carbon sources were essential in plant/pathogen/antagonist interaction. Substrates like β-methyl-D-glucoside, D-mannitol, D-galacturonic acid, N-acetyl-D-glucosamine, and phenylethylamine strongly connect with the suppuration of root rot disease. These carbon sources may help to propagate a healthy microbial community to reduce the pathogen invasion in the plant root system, and these carbon sources can be stimulators of antagonists against pathogens in the future.
