“…The isolates of pathogenic fungi Rhizoctonia solani, Fusarium solani and Macrophomina phaseolina were isolated from the root and soil of wheat plant according to Abass et al (2021). In addition, the two fungi Trichoderma koningii and Chaetomium globosum were obtained from the Laboratories of the Prevention Department/College of Agriculture/University of Basrah.…”

Abstract. Madhi QH, Abass MH, Matrood AAA. 2021. The efficiency of some bioagent fungi in reduction of wheat seed decay and seedling damping-off disease with heavy metals interaction. Biodiversitas 22: 3984-3993. Biological control is an ecofriendly efficient measurement for disease control and heavy metals reduction in soils. The use of bioagent fungi such as Trichoderma koningii and Chaetomum globosum reduced the negative effect of pathogenic fungi that cause seed decay and the seedlings damping off wheat alone or by interaction with the concentrations of lead or cadmium, which increases the germination percentage of wheat seeds and reducing seedling damping off. It also reduced the severity index of wheat with pathogenic fungi and reduced the negative effect of interaction between heavy metals and pathogenic fungi on the severity index of the wheat. Results showed that T. koningii and C. globosum reduced the effect of the interaction of R. solani with 200 mg/kg lead to 57.7 and 55.4%, respectively and R. solani and cadmium 3 mg/kg with 60 and 61.6%, respectively. T. koningii and C. globosum also reduced the effect of the interaction F.solani with lead 200 mg/kg to 45.4 and 48.5%, respectively and F. solani and cadmium 3 mg/kg to 46.8 and 52.5% respectively. The bioagent fungi also increased the fresh and dry weight of shoot and root system, T. koningii significantly increased the fresh and dry weight of shoot in the presence of R. solani. The results also indicated that there was a high significant difference in the use of C. globosum in increasing the fresh and dry weight of shoot and root system. T. koningii and C. globosum significantly reduced the effect of interaction between the pathogenic fungi and low concentrations of lead and cadmium leading to an increase in the fresh and dry weight of shoot and root system. They also increased the plant height in the presence of pathogenic fungi as well as reducing the negative effect of the interaction between heavy metals and pathogenic fungi in the height of wheat plants. No significant interaction was observed between the low concentrations of lead and cadmium and pathogenic fungi in the presence of bioagent fungi. The results exhibited that bioagent fungi can reduce the negative effect of interaction of pathogenic fungi with lead and cadmium on the total phenols content of wheat leaves, and no significant difference was recorded in the treatment of low concentrations with the pathogenic fungi. Results showed that bioagent fungi can reduce the negative effect of the interaction of pathogenic fungi with lead and cadmium on the total phenols content of wheat plant leaves. No significant differences were recorded in the treatment of low concentrations with the pathogenic fungi in the presence of bioagent fungi. The two bioagent fungi increased the concentration of chlorophyll a and b, total chlorophyll and carotenoids reduced anthocyanin in leaves, and increased chlorophyll stability index compared to the control treatment.

“…Moreover, downstream processing of the secretome requires less purification steps. It has also been reported that M. phaseolina also infects wheat seeds ( Abass et al, 2021 ). Thus, the putative virulence factors that were identified in the present study may help to deduce the infection mechanisms involved in other susceptible host plants.…”

“…Plant pathogenic fungi have the largest proportion of secreted proteins. M. phaseolina also infects wheat seeds ( Abass et al, 2021 ). In order to isolate the secretome of M. phaseolina , the fungal spore suspension was inoculated in a wheat bran matrix maintaining optimum temperature and relative humidity.…”

Secretome Analysis of Macrophomina phaseolina Identifies an Array of Putative Virulence Factors Responsible for Charcoal Rot Disease in Plants

Macrophomina phaseolina is a global devastating necrotrophic fungal pathogen. It causes charcoal rot disease in more than 500 host plants including major food crops, pulse crops, fiber crops, and oil crops. Despite having the whole-genome sequence of M. phaseolina, understanding the M. phaseolina genome-based plant–pathogen interactions is limited in the absence of direct experimental proof of secretion. Thus, it is essential to understand the host–microbe interaction and the disease pathogenesis, which can ensure global agricultural crop production and security. An in silico–predicted secretome of M. phaseolina is unable to represent the actual secretome. We could identify 117 proteins present in the secretome of M. phaseolina using liquid chromatography–electrospray ionization–tandem mass spectrometry. Data are available via ProteomeXchange with identifier PXD032749. An array of putative virulence factors of M. phaseolina were identified in the present study using solid-state culture. Similar virulence factors have been reported in other plant pathogenic fungi also. Among the secretory fungal proteins with positive economic impacts, lignocellulolytic enzymes are of prime importance. Further, we validated our results by detecting the cell wall–degrading enzymes xylanase, endoglucanase, and amylase in the secretome of M. phaseolina. The present study may provide a better understanding about the necrotrophic fungi M. phaseolina, which modulate the host plant defense barriers using secretory proteins.

“…Considering the longevity of M. phaseolina sclerotia and an almost 60-year-long four-crop (sugar beet, sunflower, corn, and wheat) agricultural system in Rimski Šančevi, with all listed crops having been reported as hosts of this pathogen, it is likely that the experimental field is highly contaminated with the sclerotia of M. phaseolina (Jacobsen, 2006;Babu et al, 2007;Abass et al, 2021;Marquez et al, 2021). The crop rotation practice applied in the experimental field is similarly applied in the wider area of Serbia, producing an environment that contributes to the problem.…”

A biotroph sets the stage for a necrotroph to play: ‘Candidatus Phytoplasma solani’ infection of sugar beet facilitated Macrophomina phaseolina root rot

et al. 2023

‘Candidatus Phytoplasma solani’ (stolbur phytoplasma) is associated with rubbery taproot disease (RTD) of sugar beet (Beta vulgaris L.), while Macrophomina phaseolina is considered the most important root rot pathogen of this plant in Serbia. The high prevalence of M. phaseolina root rot reported on sugar beet in Serbia, unmatched elsewhere in the world, coupled with the notorious tendency of RTD-affected sugar beet to rot, has prompted research into the relationship between the two diseases. This study investigates the correlation between the occurrence of sugar beet RTD and the presence of root rot fungal pathogens in a semi-field ‘Ca. P. solani’ transmission experiment with the cixiid vector Reptalus quinquecostatus (Dufour), in addition to naturally infected sugar beet in the open field. Our results showed that: (i) Reptalus quinquecostatus transmitted ‘Ca. P. solani’ to sugar beet which induced typical RTD root symptoms; (ii) Macrophomina phaseolina root rot was exclusively present in ‘Ca. P. solani’-infected sugar beet in both the semi-field experiment and naturally infected sugar beet; and that (iii) even under environmental conditions favorable to the pathogen, M. phaseolina did not infect sugar beet, unless the plants had been previously infected with phytoplasma.
