Special Issue Information

Dear Colleagues,

Disease of horticultural products, including fruit, vegetables, flowers, spice plants, and medicinal plants, is an important factor that leads to severe postharvest product decay, huge economic losses, and mycotoxin contamination. Horticultural products are susceptible to pathogenic fungi during the growth and storage period. Various pathogens that adapt to the local environment can infect different horticultural products, and they vary greatly. Therefore, the isolation and identification of pathogens causing horticultural product disease are highly necessary to control plant disease and develop specific fungicides for these different pathogens. In addition, chemical fungicides are the main strategy to manage horticultural product disease; however, a series of problems such as environmental pollution, fungicide residue, and pathogens developing resistance to fungicides are becoming more and more prominent. Induced resistance by various biotic inducers and abiotic stresses is considered a sustainable strategy to control the postharvest decay of horticultural products, which has gained increasing attention in recent years.

Therefore, we encourage manuscripts on the following topics: 1. Isolation and identification of pathogenic fungi in pre-harvest or post-harvest horticultural products; 2. New diagnosis and detection technology of pathogenic fungi in horticultural products; 3. Prevention and control methods of pathogenic fungi in horticultural products; 4. Detection and control technologies related to pathogenic mycotoxins of horticultural products; 5. Pathogenic mechanism of pathogenic fungi on horticultural products.

Fresh wet vermicelli is highly susceptible to microbial contamination during storage as a result of its high moisture content and rich nutrients, which leads to spoilage and deterioration. In addition to exerting a great impact on the quality of the product, this results in significant economic losses and potential food safety risks. This work aimed to identify spoilage microorganisms via traditional culturing methods and molecular biology techniques. The effects of environmental factors such as temperature and pH on the growth and development of the dominant spoilage fungi were investigated, and the inhibitory effects of both chemical (potassium sorbate) and natural antimicrobial agents (chitooligosaccharides, chitosan, tea polyphenols, citric acid, and ε-polylysine hydrochloride) were evaluated. The results indicated that Penicillium crustosum was the major spoilage microorganism in fresh wet vermicelli, whose optimal growth temperature and pH was 28 °C and 7, respectively. While conidial germination began at 7 h, hyphal formation was only observed after 12 h. Moreover, the findings suggest that both natural and chemical antimicrobial agents can effectively inhibit the growth of P. crustosum, with ε-polylysine hydrochloride being the strongest antimicrobial agent. Overall, the findings of this study provide a scientific foundation for improving the preservation of fresh wet vermicelli, which is of great significance for extending its shelf life and enhancing food safety.

DNA methylation is a crucial epigenetic marker linked to plant defense responses, but its significance in fungal infection of postharvest fruits remains poorly understood. This study indicated that Trichothecium roseum inoculation increased ROS production, enhanced phenylpropanoid metabolism-related enzyme activity, and promoted lignin accumulation in harvested muskmelon fruits (Cucumis melo cv. Yujinxiang) within 24 h post-inoculation (hpi). In addition, whole-genome bisulfite sequencing showed that genomic DNA methylation levels of muskmelon decreased by 6.15% at 24 hpi. Notably, CG sites exhibited a higher methylation level and the largest number of differentially methylated regions (DMRs). Moreover, 176 DMR-associated genes (DMGs) involved in the defense response, 134 DMGs in the ROS metabolic pathway, and 41 DMGs in phenylpropanoid metabolism were identified. The differentially expressed genes harboring differential methylation were mainly influenced by hypomethylation and exhibited elevated transcript levels, involved in phenylpropanoid biosynthesis and biosynthesis of secondary metabolites.

Penicillium griseofulvum CF3 is a fungus isolated from healthy strawberry soil, with the potential to promote the growth of plants and enhance their resistance to diseases. However, the genome sequence of P. griseofulvum CF3 remains unclear. Therefore, we performed the whole-genome CCS sequencing of P. griseofulvum CF3 using the PacBio Sequel II platform. The assembled genome comprised 104 contigs, with a total length of 37,564,657 bp, encoding 13,252 protein-coding genes. Comprehensive functional annotation was performed using various BLAST databases, including the non-redundant (Nr) protein sequence database, Gene Ontology (GO), the Kyoto Encyclopedia of Genes and Genomes (KEGG), EuKaryotic Orthologous Groups (KOG), and the Carbohydrate-Active enZymes (CAZy) database, to identify and predict protein-coding genes, tRNAs, and rRNAs. The Antibiotics and Secondary Metabolites Analysis Shell (Antismash) analysis identified 50 biosynthetic gene clusters involved in secondary metabolite production within the P. griseofulvum CF3 genome. The whole-genome sequencing of P. griseofulvum CF3 helps us to understand its potential mechanisms in promoting plant growth and enhancing disease resistance, paving the way for the application of the CF3 strain in sustainable crop production.

This study was conducted in order to explore the pathogens that cause stem rot of fresh onions during postharvest storage, identify the incidence of stem rot, investigate the influence of pathogen infection on the active components of onion, and provide a theoretical basis for disease control during the postharvest storage of fresh onions. The pathogens were isolated and purified from the junction between the rotten and healthy tissues of onion stem rot that occurred naturally during storage at room temperature by tissue separation; then, the pathogens were identified by morphological and molecular biological techniques, the biological characteristics of the pathogens were analyzed, and finally, the influence of pathogen infection on the active ingredients of onion was studied. The results suggested that the main pathogens causing stem rot of fresh onions during postharvest storage were Talaromyces pinophilus, Trichoderma simmonsii, and Talaromyces minioluteus. The optimum colony growth conditions for T. pinophilus were as follows: a temperature of 30 °C, a pH of 7, light for 24 h, maltose as a carbon source, and peptone as a nitrogen source; the lethal temperature was 65 °C for 15 min. For T. simmonsii, the lethal temperature was 60 °C for 15 min, and the optimum sporulation conditions were a temperature of 25 °C, a pH of 5–7, light for 24 h, a carbon source of sucrose, and a nitrogen source of yeast powder. For T. minioluteus, the lethal condition was 65 °C for 15 min; the optimum colony growth conditions were a temperature of 25 °C, a pH of 8–9, 24 h of darkness, a carbon source of maltose, and a nitrogen source of peptone. The relative content of sulfur compounds, as the active components of onions, was much lower in the infected onions than in the healthy onions due to infection by the pathogens T. pinophilus, T.simmonsii, and T.minioluteus. This study will provide a theoretical basis for further effective control of the occurrence of postharvest stem rot diseases of onions. Full article
