Summary: This review examines the progress of electrostatic spore-trapping research and the potential for practical application in powdery mildew control. Electric field screens generated by charging insulated conductor wires attract and trap pathogen spores, creating spore-free spaces for plant cultivation without the risk of airborne infection.

Summary: A novel strain of Amoebophrya sp. ex Alexandrium catenella was cultured from Osaka Bay, Japan, and found to infect not only Alexandrium but also Prorocentrum in culture, with confirmed infection in Tripos in a field sample. The parasite had a significant effect on the dynamics of A. catenella, particularly on the termination of the blooms, with a maximum prevalence of 73% during the Alexandrium bloom period in Osaka Bay.

Summary: This study compared differentially expressed genes (DEGs) between host plants inoculated with endophyte M7SB41 (Seimatosporium sp.) and endophyte-free plants in response to powdery mildew (PM) infection. The results showed that M7SB41 enhances PM resistance through Ca2+ signaling, salicylic acid (SA) signaling, and the phenylpropanoid biosynthesis pathway.

Summary: Spray-induced gene silencing (SIGS) is a promising tool for crop pest protection by utilizing exogenously applied double-stranded RNA to reduce pest target gene expression. This study optimized SIGS methods for powdery mildew fungi and identified important gene targets and processes for powdery mildew control. The efficacy of SIGS on powdery mildew makes it an exciting prospect for commercial powdery mildew control.

Summary: This review summarizes the efforts made in the past 50 plus years to identify resistant sources against powdery mildew and downy mildew in melon germplasm. A total of 239 melon accessions resistant to powdery mildew and 452 accessions resistant to downy mildew have been identified. Among these resistant sources, C. melo var. cantalupensis accessions PMR 45, PMR 5, PMR 6, and WMR 29, as well as C. melo var. momordica accessions PI 124111, PI 124112, and PI 414723, are considered as the most valuable germplasm. Genetic mapping has identified several dominant genes, recessive genes, and QTLs conferring resistance to both powdery mildew and downy mildew.

Summary: A recent taxonomic reassessment reclassified powdery mildew on Acalypha spp. into a separate genus Salmonomyces, reinstating the old genus name. Two sister species within Salmonomyces were discovered, one with both anamorph and teleomorph on Acalypha supera in South China, and the other known only by anamorph as Salmonomyces javanicus.

Summary: Powdery mildew of wheat is a highly destructive disease that poses a serious threat to crop yield and quality worldwide. Genetic research on powdery mildew (Pm) resistance has made significant progress, with the identification and cloning of many Pm genes from wheat and its wild and domesticated relatives. Moreover, modern breeding strategies, such as high-throughput sequencing and genome editing, are being developed to enhance intelligence and customization in breeding for powdery mildew resistance in wheat.

Summary: When comparing the requirements of diverse journals to publish microbial 'Genome Reports,' we found that some focus on universal single-copy orthologs scores as a quality measure, while paying less attention to excluding possible contaminating sequences and possible misidentification of target microbes. To address these issues, we suggest extracting widely accepted DNA barcodes for identification and including them in phylogenetic analyses to confirm microorganism identity before publishing Genome Reports. Additionally, contig similarity values, such as GC content, remapping coverage of WGS reads, and BLASTN searches against the NCBI nucleotide database, can also detect contamination issues. These recommendations are demonstrated through analysis and retraction of a draft genome published in Molecular Plant-Microbe Interactions due to contamination.

Summary: This study evaluated the effectiveness of hyperparasitic fungi in controlling powdery mildew. In a greenhouse, we spray-inoculated colonies of the melon PM-causing fungus with spores of the hyperparasitic fungus Ampelomyces sp. We collected and counted the conidia produced by the PM colonies and found that the hyperparasitic fungus suppressed the release of conidia. This study is the first to use electrostatic and digital microscopic techniques to assess the impact of fungal hyperparasitism on mycohost survival and quantitatively evaluate the suppression of conidial release from infected PM colonies.
