“…We employed scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to analyze the conidiophores and subcellular organelles of the N1 and ∆ PdStuA strains. As mentioned earlier [ 4 ], 100 μL of the spore suspension was coated on the PDA plates. The mycelia were collected on Days 2 and 4.…”

“…Based on previous methods [ 4 , 29 ], hyphae from N1 and Δ PdStuA mutants were gathered and frozen in liquid nitrogen after incubation for 2 d. TRIzol was used to isolate P. digitatum RNA. qPCR SYBR Green Master Mix (Vazyme, Nanjing, China) was used to prepare the reaction.…”

“…However, citrus fruit is prone to decay due to infection during harvesting, transportation, and storage [ 3 ]. Infectious pathogens (such as Penicillium digitatum , Geotrichum citri-aurantii , P. italicum , and Colletotrichum gloeosporioides ) have had a significant negative impact on the development of the citrus industry [ 2 , 4 ]. Under severe conditions, it might exceed 50% and cause significant economic losses as well as have an impact on the market supply and export sales [ 1 , 5 ].…”

Penicillium digitatum has become one of the main pathogens in citrus due to its high spore production and easy spread. In this study, the function of the APSES transcription factor StuA in P. digitatum was characterized, and the results indicated that it was involved in conidium and conidiophore development. No conidiophores were observed in the mycelium of the ∆PdStuA mutant that had grown for two days, while an abnormal conidiophore was found after another two days of incubation, and only small thin phialides as well as a very small number of spores were formed at the top of the hyphae. Moreover, it was observed that the ∆PdStuA mutant showed various defects, such as reduced hydrophobicity and decreased tolerance to cell wall inhibitors and H2O2. Compared to the original P. digitatum, the colony diameter of the ∆PdStuA mutant was not significantly affected, but the growth of aerial hyphae was obviously induced. In in vivo experiments, the spore production of the ∆PdStuA mutant grown on citrus fruit was remarkably decreased; however, there was no significant difference in the lesion diameter between the mutant and original strain. It could be inferred that less spore production might result in reduced spread in citrus, thereby reducing the green mold infection in citrus fruit during storage. This study provided a gene, PdStuA, which played key role in the sporulation of P. digitatum, and the results might provide a reference for the molecular mechanisms of sporulation in P. digitatum.

“…Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses were performed as described in previous studies (Du, Sun, Tian, Cheng, & Long, 2023;Gani et al, 2016;Songsamoe, Khunjan, & Matan, 2021). The mold cultured at 28 °C for 5 days in the PDA medium was prepared in a small piece (2 mm × 2 mm), sputtered with a layer of gold, and examined by SEM (Merlin-type, Carl Zeiss, Germany).…”

In order to solve the problem of infestation of fresh fruit after making them into candied fruit and the quality degradation caused by the infestation, a combined ozone-microwave sterilization method was used to treat four candied fruit molds.Response surface optimization analysis showed that when the ozone infusion time was at 10 min and with 560 W microwave power for 20 s, the inhibition rates of the four candied fruit molds S1, S2, X1, and H1 were 100%, 94.28%, 100%, and 100%, respectively. Moreover, according to the characterization of morphology, DNA electrophoretic profiles, and nucleic acid/protein leakage test, the integrity of the mold cell membrane was destroyed after the combined ozone-microwave treatment because of the thermal and nonthermal effects of microwave and the strongly oxidizing properties of ozone. The molds were dead because of the efflux of intracellular nucleic acid and protein and the degradation of DNA, which influenced normal cellular metabolism. Quality identification showed a better expected quality of candied fruit.
