Fusarium oxysporum is the most economically important and commonly encountered species of Fusarium. This soil-borne fungus is known to harbour both pathogenic (plant, animal and human) and non-pathogenic strains. However, in its current concept F. oxysporum is a species complex consisting of numerous cryptic species. Identification and naming these cryptic species is complicated by multiple subspecific classification systems and the lack of living ex-type material to serve as basic reference point for phylogenetic inference. Therefore, to advance and stabilise the taxonomic position of F. oxysporum as a species and allow naming of the multiple cryptic species recognised in this species complex, an epitype is designated for F. oxysporum. Using multi-locus phylogenetic inference and subtle morphological differences with the newly established epitype of F. oxysporum as reference point, 15 cryptic taxa are resolved in this study and described as species.

“…However, the phytopathogenic strains cause destructive vascular wilt disease and often limit the production of economically important crops (Servin et al, 2015, Shahzad et al, 2017). The species of Fo cause wilt disease in more than 150 hosts and range with specific formae speciales (Bertoldo et al, 2015).

Tomato (Lycopersicon esculentum) is one of the widely grown vegetables worldwide. Fusarium oxysporum f. sp. lycopersici (FOL) is the significant contributory pathogen of tomato vascular wilt. The initial symptoms of the disease appear in the lower leaves gradually, trail by wilting of the plants. It has been reported that FOL penetrates the tomato plant, colonizing and leaving the vascular tissue dark brown, and this discoloration extends to the apex, leading to the plants wilting, collapsing and dying. Therefore, it has been widely accepted that wilting caused by this fungus is the result of a combination of various physiological activities, including the accumulation of fungal mycelia in and around xylem, mycotoxin production, inactivation of host defense, and the production of tyloses; however, wilting symptoms are variable. Therefore, the selection of molecular markers may be a more effective means of screening tomato races. Several studies on the detection of FOL have been carried out and have suggested the potency of the technique for diagnosing FOL. This review focuses on biology and variability of FOL, understanding and presenting a holistic picture of the vascular wilt disease of tomato in relation to disease model, biology, virulence. We conclude that genomic and proteomic approachesare greater tools for identification of informative candidates involved in pathogenicity, which can be considered as one of the approaches in managing the disease.

“…However, Fusarium wilt disease on lisianthus, caused primarily by Fusarium oxysporum f. sp. eustomae , has become the most important threat to its production in China, Italy and Japan (Bertoldo, Gilardi, Spadaro, Gullino, & Garibaldi, ). Dazomet fumigation and various RSD treatments incorporated with different organic substrates were carried out on a soil planted continuously with lisianthus for 4 years.…”

Various soil management strategies that use disinfestation are important in the control of soil‐borne diseases before planting. However, only a few studies pay attention to preventing pathogen reinfestation during host plant cultivation, which is also important for the stable control of soil‐borne diseases. Here we used various pre‐planting management strategies to disinfest a field severely infested with Fusarium oxysporum, and then investigated changes in the potential pathogen and microbial communities during the 11 months of host plant cultivation. The soil microbial numbers, diversity, community structure and composition varied considerably across the soils treated by dazomet fumigation and reductive soil disinfestations (RSDs) using ethanol, bagasse and bean dregs. The Fusarium inoculum decreased to the same degree in the disinfested soils with the various methods. After the cultivation of lisianthus (Eustoma russellianum (Hook.) G. Don), microbial numbers, diversity and community structure tended to be similar and Fusarium increased markedly in these soils. Furthermore, the increase in relative abundance of Fusarium, especially in the RSD‐treated soils amended with bagasse, was significantly less than in the soils amended with non‐plant residues. Further analyses showed that the increases in microbial diversity and relative abundance of Zopfiella and Mycothermus were significantly and negatively correlated with the increase in Fusarium relative abundance. The additional sources of carbon supplied in the disinfested soil positively affected the development of the soil microbiota and prevented Fusarium reinfestation resulting from host plant cultivation, which should be considered for achieving stable disease suppression in the future. Highlights We studied Fusarium reinfestation resulting from host plant cultivation in various soil environments. Plant cultivation led to uniformity in the development of different soil microbiota. Fusarium reinfestation depended strongly on soil environment. Increased microbial diversity and specific microbial groups prevented Fusarium reinfestation.
