“…Examples of both synergistic and antagonistic types of interactions have been reported in natural and agricultural plant systems 19,20 . Potato (Solanum tuberosum) crops are subject to numerous diseases induced by various types of microorganisms, including viruses, bacteria, fungi, and oomycetes, and are therefore also prone to co-infection [21][22][23] . Among the s e e m a n u s c r i p t D O I f o r d e t a i l s W I T H D R A W N most common potato diseases, late blight and common scab can be considered as radically different in terms of severity of damage and impact on plant viability.…”

How do pathogens colonizing the same host interact with each other? We evaluated here the types of interactions taking place between Streptomyces scabiei and Phytophthora infestans, the causative agents of common scab and late blight diseases on potato crops, respectively. Under most conditions tested S. scabiei impaired or completely inhibited the growth of P. infestans by producing either soluble and/or volatile compounds. Media component analysis revealed that increasing peptone levels correlated with increased inhibition of P. infestans. Comparative metabolomics showed that production of S. scabiei siderophores (desferrioxamines, pyochelin, scabichelin and turgichelin) increased with the quantity of peptone thereby suggesting that they participate in the inhibition of the oomycete growth. Mass spectrometry imaging further uncovered that the zones of secreted siderophores and of P. infestans growth inhibition coincided. Moreover, either the repression of siderophore production or the neutralization of the iron-chelating activity of siderophores both led to a resumption of P. infestans growth. Importantly, replacement of peptone by natural nitrogen sources such as sodium nitrate, ammonium sulfate, and urea also triggered siderophore production in S. scabiei. Overall, our work further emphasizes the importance of competition for iron between microorganisms that colonize the same niche. As common scab never alters the biological function of tubers, we propose that S. scabiei, under certain conditions, could play a protective role for its hosts against much more destructive pathogens through exploitative iron competition and volatile compound production.

“…Our results tally with the data published in the literature. F. oxysporum was confirmed as the most common potato wilt-associated pathogen in the Mid-Volga region of Russia [ 33 ], Algeria [ 36 ], China [ 37 ], and Tunisia [ 38 ]. This species was also ranked the leading cause of dry rot in seed potato tubers in Michigan, USA [ 39 ].…”

Induced Expression of CYP51a and HK1 Genes Associated with Penconazole and Fludioxonil Resistance in the Potato Pathogen Fusarium oxysporum

et al. 2023

Preventing antifungal resistance development and identifying pathogens with high, medium, and low risk of resistance development to a particular fungicide or fungicide class is crucial in the fight against phytopathogens. We characterized the sensitivity of potato wilt-associated Fusarium oxysporum isolates to fludioxonil and penconazole and assessed the effect of these fungicides on the expression of fungal sterol-14-α-demethylase (CYP51a) and histidine kinase (HK1) genes. Penconazole stunted the growth of F. oxysporum strains at all concentrations used. While all isolates were susceptible to this fungicide, concentrations of up to 1.0 μg/mL were insufficient to cause a 50% inhibition. At low concentrations (0.63 and 1.25 μg/mL), fludioxonil stimulated growth in F. oxysporum. With an increase in the concentration of fludioxonil, only one strain (F. oxysporum S95) exhibited moderate sensitivity to the fungicide. Interaction of F. oxysporum with penconazole and fludioxonil leads to respective elevated expressions of the CYP51a and HK1 genes, which upsurge with increasing concentration of the fungicides. The data obtained indicate that fludioxonil may no longer be suitable for potato protection and its continuous use could only lead to an increased resistance with time.

“…Potato (Solanum tuberosum L.; family: Solanaceae) is an annual herbaceous plant and the fourth largest food crop in the world, providing various nutrients, such as vitamins, to humans [1]. Potato is the main food crop in China given their high consumption value, with a planting area of 4.915 million hm 2 and producing 91.881 million t, accounting for 28.3% of the global total planted area and 24.8% of the total production, respectively, in 2019 [2,3]. China currently has the largest potato planting area, yield, and harvest globally [4].…”

Potato Fusarium Wilt is a soil-borne fungal disease that can seriously harm potatoes throughout their growth period and occurs at different degrees in major potato-producing areas in China. To reduce the use of chemical agents and improve the effect of biocontrol agents, the inhibitory effects of the fermentation broth of Bacillus subtilis ZWZ-19 (B) and Trichoderma asperellum PT-29 (T) on Fusarium oxysporum were compared under single-culture and co-culture conditions. Furthermore, metabolomic analysis of the fermentation broths was conducted. The results showed that the inhibitory effect of the co-culture fermentation broth with an inoculation ratio of 1:1 (B1T1) was better than that of the separately cultured fermentation broths and had the best control effect in a potted experiment. Using LC-MS analysis, 134 metabolites were determined and classified into different types of amino acids. Furthermore, 10 metabolic pathways had the most significant variations, and 12 were related to amino acid metabolism in the KEGG analysis. A correlation analysis of the 79 differential metabolites generated through the comprehensive comparison between B, T, and B1T1 was conducted, and the results showed that highly abundant amino acids in B1T1 were correlated with amino acids in B, but not in T.
