“…In fact, sequencing of the qPCR products allowed the identification of two main different species complexes: FOSC and FIESC. Despite F. oxysporum, especially FOL and FORL, being considered as the most frequent disease agents in tomato [12][13][14], additional Fusarium species have been reported as pathogenic to some vegetables including tomato [9][10][11]. For instance, our results support the previously described information about F. equiseti as an important pathogen of tomato crop [6].…”

Tomato is one of the most important horticultural crops in the world and is severely affected by Fusarium diseases. To successfully manage these diseases, new insights on the expression of plant–pathogen interaction genes involved in immunity responses to Fusarium spp. infection are required. The aim of this study was to assess the level of infection of Fusarium spp. in field tomato samples and to evaluate the differential expression of target genes involved in plant–pathogen interactions in groups presenting different infection levels. Our study was able to detect Fusarium spp. in 16 from a total of 20 samples, proving the effectiveness of the primer set designed in the ITS region for its detection, and allowed the identification of two main different species complexes: Fusarium oxysporum and Fusarium incarnatum-equiseti. Results demonstrated that the level of infection positively influenced the expression of the transcription factor WRKY41 and the CBEF (calcium-binding EF hand family protein) genes, involved in plant innate resistance to pathogens. To the best of our knowledge, this is the first time that the expression of tomato defense-related gene expression is studied in response to Fusarium infection under natural field conditions. We highlight the importance of these studies for the identification of candidate genes to incorporate new sources of resistance in tomato and achieve sustainable plant disease management.

“…Root and stem tissues were sampled from 10 symptomatic plants and washed with running tap water for about 30 min, then surface-sterilized with 75% (v/v) ethanol for 5 min, rinsed in sterilized water three times and dried with sterile filter paper. The discolored vascular tissues were cut into 5-mm-long segments and plated on potato dextrose agar (PDA) containing 0.1% w/v ampicillin to inhibit bacterial growth (Li et al 2017), then cultured in the dark at 25°C, and colony morphology, size, color and growth rate as differentiating variables, were monitored daily. Individual fungal colonies were purified by singlespore isolation, and spores were preserved and stored in 25% v/v glycerin at -80°C (Brady et al 2011).…”

Boxelder maple (Acer negundo L.) is widely grown as ornamental trees in China. In 2017 in Pizhou, Jiangsu Province, China, the boxelder maple trees suffered from a disease which caused wilting and yellowing leaves, rotted roots, and discolored xylem. The disease broke out from July to August. Seven fungal isolates were obtained from symptomatic tissue and tested for pathogenicity. Isolate An7 was isolated at high frequency from the discolored vascular tissues, which caused the wilt disease on healthy 2-year-old seedlings after inoculation and eventually killed all the seedlings. We conducted molecular analysis for An7, including the partial sequences of the rDNA internal transcribed spacer, calmodulin, RNA polymerase II second largest subunit and the translation elongation factor 1-a and evaluation of the variously sized conidia, chlamydospores and conidiophores and cultural traits. The pathogen was identified as Fusarium nirenbergiae, a member of the Fusarium oxysporum species complex. To our knowledge, this is the first report of F. nirenbergiae causing wilt on A. negundo in China.

“…Several studies have reported that Fusarium wilt (FW), caused by Fusarium spp., is the primary soil-borne disease in substrate vegetables production due to the continuous use of substrates. FW occurs in cucumbers, tomatoes, watermelons, eggplants, peppers, lettuce, and carnations, which are mainly infected with Fusarium oxysporum [4][5][6][7][8]. Currently, FW limits the production of vegetables in soilless media [6].…”

Application of 6-Pentyl-α-Pyrone in the Nutrient Solution Used in Tomato Soilless Cultivation to Inhibit Fusarium oxysporum HF-26 Growth and Development

Soilless cultivation has increased in China. Like vegetables or ornamental plants, tomatoes can be cultivated in soilless culture systems. Fusarium wilt (FW) is an economic tomato disease. The nature and amount of volatile organic compounds in Trichoderma asperellum PT-15 were investigated, and 6-pentyl-α-pyrone (6-PP) was detected. Furthermore, the effect of 6-PP on Fusarium oxysporum HF-26 was evaluated. Results revealed that 25 mg/L 6-PP was the optimal concentration inhibiting F. oxysporum HF-26 and that the content of fusaric acid decreased considerably compared to that of the control. FUB1, FUB4, and FUB10 toxin synthesis and transport genes were downregulated. Additionally, VelA, velB, and LaeA genes were downregulated, reducing F. oxysporum mycelial growth and hyphae formation. 6-PP was added to the soilless culture solution in a greenhouse experiment. The results showed that an antifungal–nutrient solution containing 25 mg/L 6-PP significantly suppressed FW with 70.71% efficacy and a 27.23% disease index (DI), which were higher efficacy and lower DI than that of the control. Furthermore, treatment with an antifungal–nutrient solution containing 6-PP increased the levels of defence enzymes 24 h post-inoculation (hpi) compared with those at other time periods. The relative expression levels of the PR1, NPR1, PR2, and PR5 genes were considerably upregulated at 24 hpi.
