“…Как правило, все они имеют необильный воздушный мицелий и типичную кремовую -нежно-персиковую окраску при выращивании на КСА. Однако известно, что в пределах одного и того же вида F. sambucinum sensu stricto встречаются культуры красной, розовой или желтой окраски (Nirenberg, 1995;Logrieco et al, 1995;Baturo-Ciesniewska et al, 2015) (Peters et al, 2008;Gachango et al, 2012;Stefańczyk et al, 2016;Azil et al, 2021;Tiwari et al, 2023).

Among the 140 isolates collected from symptomatic potato tubers in four different European regions of Russia in 2021–2022, as many as 37.8 % isolates were identified as Fusarium sambucinum. Randomly selected isolates (n=19) of F. sambucinum were identified with DNA sequence data of the TEF locus and morphological characteristics on nutrient media. The growth rate of strains on potato-sucrose agar was assessed in the temperature range of 5–35 °C. The temperature optimum for growth of all strains was set at 25 °C, the average growth rate of strains was 13.68 ± 0.67 mm/day. The upper critical temperature completely arresting growth of strains was 35 °C, while at the temperature of 5 °C the strains were still able to grow at an average rate of 0.85 ± 0.27 mm/day. Fusarium sambucinum strains were characterized by their ability to produce symptoms of rot in potato tubers after inoculation and further incubation at 5 and 23 °C. Most strains caused extensive necrosis at the higher temperature, but there were strains whose aggressiveness was not affected by temperature. There is no clearly defined relationship between the origin of F. sambucinum strains and their aggressiveness.

Conventional methods of quantifying the chemical content of potatoes at different storage temperatures are time-consuming and expensive. This research studied the Visible and Near Infrared (Vis-NIR) spectroscopy for possible rapid and nondestructive methods. In this study, healthy and Fusarium spp. Potato seeds of Granola L varieties were infected artificially through the process of inoculation of fungi, and healthy potatoes were stored in various post-harvest storage conditions, namely temperatures 12°C, 25°C and a combination of temperatures 12°C and 25°C. VIS-NIR spectral data from seeds are observed periodically during the storage period. The study results showed that Vis-NIR predicted sucrose content in potatoes. The best-developed PLSR calibration model for potatoes stored at 25°C and a combination of 12°C and 25°C show R2c of 0.87 and 0.83 and RMSEC of 0.26 and 0.28. The models also successfully predicted the sugar content of potato stored at 25°C and a combination of temperatures 12°C and 25°C with R2p 0.75 and 0.78, RMSEP of 0.36 and 0.32, and RPD of 1.99 and 2.81 for sucrose. The developed model of sucrose content or potato storage temperatures of 12°C is not recommended for monitoring and detection due to the low RPD < 1.9 even though the R2c values are 0.65 – 0.9. the results of this investigation indicate that VIS-NIR spectroscopy could potentially serve as a tool for quantifying the chemical composition of potatoes during post-harvest storage.

“…The plant pathogen Fusarium spp., which causes host plant wilt in the field and Fusarium dry rot during storage, has become a global threat to crop growth, transportation, and storage ( Tiwari et al, 2021a ; Tiwari et al, 2021b ; Tiwari et al, 2023 ). However, the control methods for Fusarium spp.…”

Tomato wilt is a widespread soilborne disease of tomato that has caused significant yield losses in many tomato growing regions of the world. Previously, it was reported that tomato wilt can be caused by many pathogens, such as Fusarium oxysporum, Ralstonia solanacearum, Ralstonia pseudosolanacearum, Fusarium acuminatum, and Plectosphaerella cucumerina. In addition, we have already reported that Fusarium brachygibbosum caused symptomatic disease of tomato wilt for the first time in China. The symptoms of tomato wilt caused by these pathogens are similar, making it difficult to distinguish them in the field. However, F. brachygibbosum specific identification method has not been reported. Therefore, it is of great importance to develop a rapid and reliable diagnostic method for Fusarium brachygibbosum to establish a more effective plan to control the disease. In this study, we designed F. brachygibbosum-specific forward primers and reverse primers with a fragment size of 283bp located in the gene encoding carbamoyl phosphate synthase arginine-specific large chain by whole genome sequence comparison analysis of the genomes of eight Fusarium spp.. We then tested different dNTP, Mg2+ concentrations, and annealing temperatures to determine the optimal parameters for the PCR system. We evaluated the specificity, sensitivity and stability of the PCR system based on the optimized reaction system and conditions. The PCR system can specifically identify the target pathogens from different fungal pathogens, and the lower detection limit of the target pathogens is at concentrations of 10 pg/uL. In addition, we can accurately identify F. brachygibbosum in tomato samples using the optimized PCR method. These results prove that the PCR method developed in this study can accurately identify and diagnose F. brachygibbosum.
