“…However, sophorose showed significant positive correlation with varietal resistance to FHB. In previous research [ 50 ], a negative significant correlation was found between heptadecanoic acid and Fusarium wilt incidence, where authors concluded that a positive r value may indicate that fatty acids had stimulatory effects on the growth and sporulation of cottonseed fungi, while a negative r value could be attributed to inhibitory activities of fatty acids. Thus, it can be concluded that in the current research, sophorose directly influenced varietal resistance to Fusarium , while heptadecanoic acid and 9-(Z)-hexadecenoic acid through lipid metabolism indirectly influenced resistance.…”

Fusarium head blight (FHB) is one of the most dangerous diseases of winter wheat, resulting in reduced grain yield and quality, and production of mycotoxins by the Fusarium fungi. In the present study, changes in the grain metabolomics of winter wheat samples infected with Fusarium spp. and corresponding non-infected samples from two locations in Croatia were investigated by GC-MS. A Mann–Whitney test revealed that 24 metabolites detected were significantly separated between Fusarium-inoculated and non-infected samples during the variety by treatment interactions. The results confirmed that in grains of six FHB-resistant varieties, ten metabolites were identified as possible resistance-related metabolites. These metabolites included heptadecanoic acid, 9-(Z)-hexadecenoic acid, sophorose, and secolaganin in grains of FHB-resistant varieties at the Osijek location, as well as 2-methylaminomethyltartronic acid, maleamic acid, 4-hydroxyphenylacetonitrile, 1,4-lactonearabinonic acid, secolaganin, and alanine in grains of FHB-resistant varieties at the Tovarnik location. Moreover, on the PCA bi-plot, FHB-susceptible wheat varieties were closer to glycyl proline, decanoic acid, and lactic acid dimer that could have affected other metabolites, and thus, suppressed resistance to FHB. Although defense reactions were genetically conditioned and variety specific, resulting metabolomics changes may give insight into defense-related pathways that could be manipulated to engineer plants with improved resistance to the pathogen.

Relationship between Fusarium Wilt Disease and Fatty Acids Content of Cottonseed

Abstract: Ten genotypes of cotton were evaluated for resistance to Fusarium wilt cause by Fusarium oxysporum f. sp. vasinfectum. The genotypes were divided into two groups based on their reactions to the disease. The first group included five susceptible genotypes (9
