Summary: Grafting enhances watermelon resistance against Fusarium oxysporum f.sp. niveum infection by upregulating pathogenesis-related proteases, inducing differential accumulation of proteins in leaves, and promoting the roles of protein biosynthesis and stress defense-related proteins. Signal transduction proteins positively regulate the defense process, while carbohydrate and energy metabolism contribute to energy production in grafted watermelon seedlings under infection. Enhanced scavenging capacity of reactive oxygen species (ROS) may also contribute to the disease resistance of grafted watermelon seedlings.

Summary: Watermelon is an important commercial crop, but its production is significantly limited by fusarium wilt caused by the fungus Fon. Management strategies include rotation, improved resistance, and chemical control, but accurate diagnostics are crucial. Molecular strategies for diagnostics greatly reduce the time needed for diagnosis.

Summary: The present study aimed to map the resistance to Fusarium oxysporum f. sp. niveum (Fon) race 2 in a highly resistant Citrullus lanatus accession (EC794421). Two statistically significant genomic regions were identified on chromosome 1 and chromosome 7, providing valuable information for marker-assisted introgression of Fon race 2 resistance into elite watermelon varieties without linkage drag.

Summary: This study aimed to identify QTL regions controlling ovary, fruit, and seed phenotypes in watermelon. Through whole genome sequencing and SNP analysis, a genetic map was constructed, and 33 QTLs were identified across the eight chromosomes of watermelon. These QTLs explained 5.32-25.99% of the phenotypic variance.

Summary: Ascochyta blight, caused by the fungal pathogen Ascochyta rabiei, is a significant threat to chickpea cultivation worldwide. This study identified four genomic regions associated with Ascochyta blight resistance, among which the LOC101507066 gene showed the most potential as a candidate gene.

Summary: Fusarium wilt of watermelon, caused by Fusarium oxysporum f. sp. niveum (FON), is a major constraint in watermelon production globally. This study developed a new PCR marker that could differentiate between the three races of FON, along with two previously published markers, improving race differentiation accuracy.

Summary: This study investigated the pathogen population structure of Fusarium wilt of watermelon in Florida using multilocus sequence analysis, showing that using highly conserved housekeeping genes and loci did not clearly group and delineate different Fon races. Additionally, there were significant variations in aggressiveness among different isolates, indicating the need for future whole genome sequencing efforts to provide higher resolution of genetic distinctions within the species.

Summary: Bacillus amyloliquefaciens strain NCPSJ7 exhibits potential fungicidal activities, and the active antifungal compound C14-iturin A is identified to inhibit the growth of fungi. Furthermore, LPs cause damage to fungal cell wall and membrane, leading to the inhibition of fungal development and reproduction.

Summary: Fon is the causative agent of Fusarium wilt disease of watermelon, causing significant yield losses worldwide. Initial symptoms include loss of turgor pressure and eventual necrosis, affecting proper water movement in the plant. Correct identification of the pathogen and use of molecular markers are crucial for disease control.
