Summary: This study identified two genes responsible for resistance against the azuki bean weevil in TN67 and identified candidate genes for this resistance. Comparative genomics confirmed the presence of two tandemly duplicated genes, VacPGIP1 and VacPGIP2, which are likely key players in conferring resistance.

Summary: This study analyzed and detected the pathogenicity of Fusarium andiyazi, a member of the Fusarium fujikuroi species complex, on rice plants in Turkey. The results showed that F. andiyazi can cause Bakanae disease in rice, leading to inhibited seed germination and abnormal plant elongation.

Summary: This study investigated the symptoms and pathogens diversity of corn Fusarium sheath rot in 21 county-level regions in 12 prefecture-level districts of Sichuan Province from 2015 to 2018. The main pathogens identified were F. verticillioides and F. proliferatum, with a high rate of mixed infection of multiple Fusarium species. Pathogenicity tests showed that F. proliferatum and F. fujikuroi exhibited the highest virulence among the identified pathogens.

Summary: In this bioprospection survey, a pectinolytic fungal strain, Fusarium proliferatum, was isolated from agro-industrial residues, showing polygalacturonase (PGAse) activity with optimal activity at pH 3.6 and 43.4 degrees C. Endo-PGAse produced by F. proliferatum P6 could be valuable for industries such as wine production and fruit and vegetable processing.

Summary: This review summarizes recent research activities on the antifungal and anti-mycotoxigenic activity of natural phenolic compounds against Fusarium, including their mechanisms of action, structure-activity interaction, and combined effects with other natural products or conventional fungicides. The role of high-throughput analysis tools and sustainable formulations to enhance inhibitors' efficacy are also discussed.

Summary: The Snf1 kinase plays an important role in the virulence, nutrition and conidiation of the necrotrophic fungus Botrytis cinerea. The deletion of the Bcsnf1 gene reduces the pathogenicity and growth rate of the fungus, as well as the secretion of xylanase activities. The mutants also show defects in pH regulation, asexual sporulation and macroconidia production.

Summary: The negative impact of conventional fungicides has led to an increased interest in safer alternatives such as plant secondary metabolites. Plant cell culture technology can provide homogeneous biomasses with specific chemical characteristics. A phytocomplex from a selected cell line of Salvia officinalis demonstrated high effectiveness against the grapevine downy mildew pathogen.

Summary: Synthesized water-soluble peptide analogs show promising potential as an effective control measure against grapevine downy mildew. These peptides demonstrated high efficacy in preventing infection and reducing disease severity in field trials without showing any phytotoxic effects. Further investigation is warranted to explore their potential as a broad-spectrum fungicide.

Summary: The commercial and sanitary qualities of cereals determine the final application and destination of the grain. The cultivation area of sorghum has been increasing in Italy and is often adjacent to maize fields, leading to the risk of sharing mycotoxigenic fungi such as Fusarium verticillioides. This study explores the commonalities and differences in fungal physiology and plant growth parameters between F. verticillioides strains from maize and sorghum.

Summary: This study investigated the effectiveness of the fungicide Sedaxane as a seed treatment for oilseed rape. The results showed that all fungicide treatments, especially Thiram, greatly reduced the presence of Rhizoctonia DNA. Seedlings treated with Sedaxane exhibited significant root biostimulation in the presence of Rhizoctonia.

Summary: Black rot, caused by Xanthomonas campestris pv. campestris (Xcc), is a destructive disease affecting crucifers. Copper-based products, despite their potential negative effects, are currently used to manage the pathogen. Trichoderma spp. has been used as a biocontrol agent against various phytopathogens. In this study, synthetic analogs of the peptaibol trichogin GA IV were tested for their antimicrobial activity against Xcc and other bacteria, and one of the peptides (4r) showed effectiveness in reducing black rot symptoms on cauliflower plants. The cytotoxic activity of peptide 4r on tobacco cells was also evaluated.

Summary: This study successfully expressed MoAA16 heterologously in Pichia pastoris and revealed its cellulose-active PMO properties. MoAA16 can break down cellulose through oxidation and enhance cellulase hydrolysis, resulting in the production of more monosaccharide products. These findings highlight the potential of MoAA16 for applications in biofuel production and chemical synthesis.
