“…These isolates might be secondary pathogens or might require specific environmental factors that were not reproduced in the laboratory to cause infection. Less abundant but definitely pathogenic were F. sambucinum, F. avenaceum, F. culmorum and F. graminearum, and these results are in accordance with those of earlier reports (Peters et al 2008b;Du et al 2012). In our study, statistical analysis performed on the four of pathogenic Fusarium spp.…”

“…isolates of F. sambucinum have caused significantly larger lesions than the isolates of other tested species (Gachango et al 2012). In potato dry rot samples, Fusarium isolates that are non-pathogenic to potato in the laboratory assessment are frequently identified (Peters et al 2008a;Peters et al 2008b). Therefore, it is interesting to know which species are present in potato tubers regardless of their role, so the risk of possible mycotoxin contamination can be estimated.…”

Fusarium spp. belong to the division Ascomycota and cause important plant diseases; these fungi may contaminate food products with mycotoxins, endangering human and animal health. Several Fusarium spp. have been associated with potato dry rot. The most frequent and devastating of these species are F. sambucinum, F. solani and F. oxysporum, depending on the geographic location and the season. Samples of potato tubers with dry rot symptoms were collected, and their putative fungal isolates were identified as Fusarium species using partial nucleotide sequences of the internal transcribed spacer, translation elongation factor 1-α and β-tubulin genes. Among 149 isolates, 12 species were identified. F. oxysporum was the most frequent (45 % of the isolates), followed by F. avenaceum (12.1 %), F. solani (10.7 %) and F. sambucinum (7.4 %). Phylogenetic analyses confirmed the species identifications and revealed a high diversity of F. solani and a low diversity of F. oxysporum. Potential producers of zearalenone and trichothecenes were identified within the obtained isolates using PCR markers. Isolates that were pathogenic to potatoes in laboratory tests were found in four species: F. sambucinum, F. avenaceum, F. culmorum, and F. graminearum. The effects of increased temperature and mixed inoculum on the pathogenicities of chosen species were evaluated. This study adds 434 potato-derived Fusarium sequences to the NCBI GenBank database and demonstrates that the list of Fusarium species and mycotoxins present in potato tubers may be richer than previously believed, regardless of whether these species cause dry rot or live as saprophytes.

“…F. sambucinum was identified as the most prevalent species causing dry rot in Gansu Province of China. These results were confirmed by Li et al (2007), while F. solani has frequently been identified as one of the most common dry rot causing species (Hanson et al 1996;Choiseul et al 2007;Peters et al 2008a;Peters et al 2008b). It was, however, not present in the present survey.…”

Dry rot is a serious potato disease and causes significant losses in China. Research efforts on potato dry rot have been very limited as well as the attempts to characterize the pathogen in the major potato production regions of China. A total of 260 Fusarium isolates were identified in 698 potato tubers collected in six important potato production regions of northern China, out of which five different Fusarium species, Fusarium sambucinum, F. avenaceum, F. oxysporum, F. equiseti, and F. acuminatum, were isolated. The identification of each species was confirmed by sequencing analysis of ∼700 bp DNA fragment derived from the translation elongation factor-1 alpha gene. F. sambucinum was found to be the predominant species accounting for 56% of the isolates. Different pathogenicity was found to be associated with five most common Fusarium species. Sixty-seven clones used in China were identified as susceptible to F. sambucinum, indicating little scope for developing resistant cultivars using the currently available potato germplasm.

Phylogeny and pathogenicity of Fusarium solani species complex (FSSC) associated with potato tubers

et al. 2021

Potato (Solanum tuberosum L.) is one of the known five crops cultivated throughout the world after corn, barley, cereals, rice, and wheat, due to its content of high carbohydrates. In developing countries, potatoes are especially had valuable contents as a rich source of starch, vitamins C and B6, and essential amino acids. Fusarium solani species complex (FSSC) is one of the prevalent pathogens of potato, causing dry rot in Upper Egypt. In this study, FSSC were isolated and identified from potato tubers based on the morphological and molecular characteristics. F. solani isolates (187) were isolated from infected and noninfected potato tubers collected from various markets in Upper Egypt. Based on the morphology observations, sequence data from amplifying β‐tubulin, and specific translation elongation factor (TEF‐1α) genes, all of the chosen 88 FSSC isolates were grouped into three major groups (F. keratoplasticum, F. falciforme, and F. solani). All the tested FSSC were able to produce amylases. The selected isolates were examined for their pathogenic ability on healthy potato tubers, which exhibited pathogenic effects; with lesions sizes were quite variable. F. solani SVUFs73 showed a highly virulent effect.
