“…Induction of PAL by fluorescent pseudomonads was also reported in rice against blast (Magnaporthe oryzae; Suguna et al, 2020), tomato against wilt (F. oxysporum f. sp. lycopersici; Ramamoorthy et al, 2002), and mango against stem-end rot (Lasiodiplodia theobromae; Seethapathy et al, 2016).…”

The tomato, one of the world’s most extensively cultivated and consumed vegetable crops is negatively impacted by various pathogens. This study aimed to observe the differentially expressed proteins in tomato samples in plant–pathogen-biocontrol interactions. The fungal pathogen associated with wilted plants were isolated and identified based on its morphological and molecular characteristics. Fourteen strains of Pseudomonas fluorescens from agricultural soils were identified and described using biochemical assays, molecular analyses, and screening for antagonistic ability against the Fusarium wilt pathogen. Results demonstrated that the potential of P. fluorescens (TPf12) positively influenced the expression of antagonism against tomato wilt disease. A total of 14 proteins expressed differently were revealed in the 2D-PAGE-MS investigation. Proteins such as nucleoside diphosphate kinase, phenylalanine ammonia-lyase, protein kinase family protein, Ser/Thr protein kinase-like are unchanged in FOL pathogen interaction, but up-regulated in FOL + TPf12 treated roots, and lipid transfer-like protein, and phenylalanine ammonia-lyase were down-regulated in FOL infested roots and upregulated in FOL + TPf12 treated tomato roots. Phenylalanine ammonia-lyase protein expression is commonly found in TPf12 bioenriched roots, and FOL + TPf12 treated roots, indicating its role in response to the application of TPf12 in tomato. A GC–MS analysis was performed to detect the bioactive metabolites synthesized by TPf12. Molecular docking investigations were conducted using the maestro’s GLIDE docking module of the Schrodinger Software program. Among the secondary metabolites, Cyclohexanepropanoic acid, 2-oxo-, methyl ester (CAS), and 3-o-(4-o-Beta-D-Galactopyranosyl-Beta-D-Galactopyraosyl)-2-Acetylamino-2-Deoxy-D-Galactose were shown to be top-ranked with a least docking score against each differently expressed proteins. The profiled molecules expressed differently due to plant-pathogen-biocontrol interactions may be directly or incidentally involved in the wilt disease resistance of tomato plants.

“…It significantly triggered the activity of defense related enzymes viz: peroxidase (PO), polyphenol oxidase (PPO) and phenylalanine ammonia lyase (PAL). This result was observed due to induced systemic resistance (ISR) (Suguna et al 2020). Moreover, induced resistance was also observed against plant viruses.…”

The phyllosphere refers to the entire aerial habitat of plants while phylloplane describes the entire leaf surface. The phylloplane provides a niche for diversified microbial communities and as such it is an important ecosystem both ecologically and economically. For many years, phylloplane dwellers have been studied as bio protectants and enhancers of growth in host plants. Plants and phylloplane-microbial-interactions result in increased fitness and productivity of agricultural crops. In this study, an attempt was made to compile previous studies in order to better understand the role of phylloplane microbiota in influencing the physiology of flora. We also proposed possible further research to explore molecular aspects of signaling mechanisms established by the phylloplane microbial community with their hosts which impact the latter's physiology.

“…Overexpression of these genes triggers the production of defense-related proteins [68]. The increase in chitinases, B-1,3-glucanases, peroxidases, lipoxygenases, superoxide dismutases, phenylalanine lyases, and polyphenol oxidase phytoalexins, as well as the formation of protective biopolymers such as lignin, callose, and hydroxyproline, are among the defense mechanisms expressed following ISR [68,70]. ISR has been highlighted in several studies as the primary mechanism responsible for biocontrol activity against S. sclerotiorum, as summarized in Table 2.…”

The fungal pathogen Sclerotinia sclerotiorum (Helotiales: Sclerotiniaceae) causes white mold, a disease that leads to substantial losses on a wide variety of hosts throughout the world. This economically important fungus affects yield and seed quality, and its control mostly relies on the use of environmentally damaging fungicides. This review aimed to present the latest discoveries on microorganisms and the biocontrol mechanisms used against white mold. A special focus is put on the identification of biocontrol desirable traits required for efficient disease control. A better understanding of the mechanisms involved and the conditions required for their action is also essential to ensure a successful implementation of biocontrol under commercial field conditions. In this review, a brief introduction on the pathogen, its disease cycle, and its main pathogenicity factors is presented, followed by a thorough description of the microorganisms that have so far demonstrated biocontrol potential against white mold and the mechanisms they use to achieve control. Antibiosis, induced systemic resistance, mycoparasitism, and hypovirulence are discussed. Finally, based on our actual knowledge, the best control strategies against S. sclerotiorum that are likely to succeed commercially are discussed, including combining biocontrol desirable traits of particular interest.
