“…Toxins produced by fungi are also important pathogenic factors. By destroying the cell membrane system, they affect the metabolism and energy synthesis of the host, resulting in physiological disorders and the occurrence of diseases (Barad et al ., 2014; Xue et al ., 2017). Environmental pH affected mycotoxins production (Zong et al ., 2015), indicating that PacC may be involved in the biosynthesis of mycotoxins.…”

pH is one of the important environmental factors that affect the growth, development and pathogenicity of postharvest pathogen. The transcription factor PacC dominates the pH signal pathway. PacC in Trichothecium roseum showed three typical conserved zinc finger domains and closest homology to Fusarium graminearum. T. roseum increased the environmental pH both in vitro and in vivo. Expression patterns of TrpacC under different pH showed that at increasing pH from 3 to 5, the wild-type (WT) strain induced the expression of TrPacC in parallel to increased fungal growth; however, TrPacC expression decline at higer pH than 5, while fungal growth continued to increase. Development of a ΔTrPacC mutant down-regulated the expression of TrbrlA, TrabaA and TrwetA, reduced sporulation and delayed spore germination, resulting in smaller spores and sparse hyphae. ΔTrPacC mutant was sensitive to ionic stress, oxidative stress and cell wall integrity stress compared to the WT strain, especially the ionic stress. In addition, ΔTrPacC mutant showed reduced pathogenicity to muskmelon and tomato fruits. Taken together, T. roseum is an alkalinizing fungus, and the acidic environment could induce TrPacC expression. TrPacC positively regulates fungal growth and development as well as pathogenicity showing effect on fungal response to different stresses.

“…Raigond et al [ 91 ] indicated that chitosan application significantly managed dry rot in potato, and he also found that a chitosan coating significantly reduced Fusarium incidence by inhibiting Fusarium growth. Xue et al [ 7 ] suggested that chitosan, sodium silicate and β-aminobutyric acid treatments markedly inhibited the expansion of lesion diameter in tubers infected with F. sulphureum . Interestingly, the trichothecene concentration was also decreased; the involved action mechanism was attributed to the up-regulation of enzyme activities involved in the defence response, and down-regulated genes were related to the trichothecene biosynthesis pathway.…”

“…Nevertheless, chemical synthetic fungicides are not a long-term solution due to the ecological environment and drug resistance. Currently, some eco-friendly control measures such as the use of some organic acids and salts [ 7 ], inorganic salts [ 8 , 9 ], chitosan [ 10 ], plant essential oil [ 11 , 12 ] and biological antagonists [ 13 , 14 ] for the management of post-harvest disease in potato tubers are being explored and developed. The present review focuses on dry rot occurrence (including the causal pathogens of dry rot, the symptoms of dry rot, and its pathogenesis), mycotoxin production (non-trichothecenes and trichothecenes), and management strategies.…”

Fusarium dry rot is one of the major potato diseases during storage after harvest, which not only results in quality degradation but also causes great economic losses. The disease can be elicited by some species of Fusarium, and the pathogenic fungi of Fusarium causing potato dry rot are considerably diverse in various countries and regions. The disease caused by Fusarium spp. is associated with mycotoxins accumulation, which has phytotoxic and mycotoxic effects on humans and animals. Chemical synthetic fungicide is considered the main control measure for the Fusarium dry rot of potato; nevertheless, it is unfortunate that persistent application inevitably results in the emergency of a resistant strain and environmental contamination. A comprehensive disease control strategy includes potato cultivar selection, appropriate cultural practices (crop rotation, cultivate pattern, fertilization, and irrigation), harvesting processes and postharvest treatments (harvesting, classification, packaging, wound healing), and storage conditions (environmental disinfection, temperature, humidity and gas composition) along with the application of fungicide pre-harvest or post-harvest. Recently, emerging studies have indicated that eco-friendly strategies include physical control, chemical methods (such as the application of generally-recognised-as-safe (GRAS) compounds or chemical (elicitors) and biological control have been introduced to combat the Fusarium dry rot of potato.

Fusarium dry rot is one of the major postharvest potato diseases of during storage after harvest, which not only results in quality degradation but also brings up huge economic losses. The dis-ease can be elicited by some species of Fusarium, the pathogenic fungi of Fusarium causing potato dry rot are considerably diverse in various countries and regions. Fusarium spp. infection is as-sociated with dry rot produce mycotoxins, which has phytotoxicity and mycotoxicoses on hu-mans and animals. Chemical synthetic fungicide is considered as the main control measure to Fusarium dry rot of potato, nevertheless, it is unfortunate that the persistent application inevitably results in the emergency of resistant strain and environmental contamination. A comprehensive disease control strategy includes potato cultivar selection, appropriate cultural practices (crop rotation, cultivate pattern, fertilization, and irrigation), harvesting process and postharvest treatment (harvesting, classification, packaging, wound healing), storage condition (environ-mental disinfection, temperature, humidity and gas composition) along with the application of fungicide pre-harvest or postharvest. Recently, emerging studies indicated that eco-friendly strategies include physical control, chemical methods (such as the application of generally rec-ognized as safe (GRAS) compounds or chemical (elicitors) and biological control have been in-troduced to combat Fusarium dry rot of potato.
