Summary: In this study, ASM treatment increased H2O2 content and reduced antioxidant contents in apples, while EGTA + ASM treatment had the opposite effect. ASM treatment enhanced the activities of multiple enzymes but inhibited catalase activity, while EGTA + ASM treatment suppressed the activities of these enzymes. CDPKs play a crucial role in regulating ROS metabolism and inducing resistance in apples through ASM treatment.

Summary: This study found that 1.0 g L-1 ferulic acid has significant induced resistance against blue mold of apples. It reduces lesion diameter and colony diameter, and enhances the activities and gene expressions of key enzymes involved in phenylpropanoid pathway and reactive oxygen species metabolism. This leads to the synthesis of antioxidants and secondary metabolites, thereby increasing disease resistance of apples.

Summary: In this study, a genome-wide comprehensive analysis of WOX genes in nine Rosaceae species was conducted, and their potential roles in Malus were investigated. The results revealed significant collinearity in Prunus. domestica among the Rosaceae species. The study also categorized the cis-elements in the WOX gene family into three categories and found that overexpression of MdWOX13-1 increased callus weight and enhanced ROS scavenging against drought stress by directly binding to the MdMnSOD promoter.

Summary: Apple production is significantly affected by apple scab disease caused by the fungus Venturia inaequalis. Breeding for polyploid cultivars could enhance resistance of apple cultivars against different V. inaequalis isolates. The role of polyploidy in conferring resistance to biotic challenges is plant-pathogen-specific.

Summary: The study investigated the potential role of MAPK in light-induced anthocyanin accumulation in apple peels, finding that MdMPK4 proteins phosphorylate MdMYB1 to increase its stability under light conditions. Light-induced anthocyanin accumulation relies on MdMPK4 kinase activity, which is essential for maximizing MdMYB1 activity. Based on the results, a potential biotechnological strategy for increasing fruit anthocyanin content via light induction is suggested.

Summary: This communication addresses the issue of discrepant ssID information for 78 SNPs on the 8K IRSC apple SNP array and reports the correct NCBI ssIDs for these SNPs in order to accurately aggregate historical SNP data and prevent the perpetuation of misassigned sslDs in further publications.

Summary: The study investigated the distribution of streptomycin-resistant Erwinia amylovora strains in major apple production regions of New York over the past 6 years, revealing a few cosmopolitan strains and novel CRISPR profile diversity across regions. Streptomycin-resistant E. amylovora was detected in a small area and associated with specific CRISPR profile, suggesting the original strain was not fully eradicated and went undetected due to low disease pressure.

Summary: A simple strategy was provided to regulate the morphology and microstructure of (5-MnO2 via the hydrothermal reaction temperature, which improved the reactivity and lifetime of catalysts in the catalytic ozonation of toluene. The optimized MnO2-260 catalyst showed high catalytic activity and excellent stability at the approximately ambient temperature of 40 degrees C. Surface oxygen vacancy clusters, especially surface oxygen dimer vacancies, were found to be critical in ozone activation.

Summary: Biofumigation with thyme, savoury, and basil essential oils effectively inhibits the development of grey mould rot in apples caused by Botrytis cinerea. Thyme and savoury oils at 1% concentration significantly reduce the incidence of grey mould rot after 60 days of storage. Biofumigation also alters the species and abundance of microorganisms on the apple surface and inside the fruit.

Summary: This study identifies the first QTL associated with resistance to Neonectria ditissima in apple scion germplasm. The results show that the QTL present in commonly used apple breeding germplasm have a low to medium effect on resistance to N. ditissima. Therefore, multiple QTL need to be considered to improve resistance through breeding.

Summary: The study found that foliar silicon treatment does not reduce decay incidence in 'Galaxy' apples after cold storage, and in some cases, it may even increase decay incidence. The treatment also does not increase physiological disorders in the fruit, but it may enhance ripening metabolism in certain periods.

Summary: The butanol fraction of apple leaves (BLE) exhibited gastro-protective and healing effects against indomethacin-induced gastric ulcers in rats. It reduced oxidative stress, inflammatory cytokines, and COX-2 expression and increased mucoglycoproteins and HSP70 expression. These effects are likely due to the presence of phytoconstituents.

Summary: The study investigated the potential interaction between genetic and induced resistance in apple against scab and fire blight diseases. They found that ASM was effective in reducing both diseases, and that resistance QTLs and ASM-induced resistance complementarily reduced symptoms by 85% to 100%.
