Bottom Line: Some classes of lipids actively determine the fate of the interactions.Host cuticle/cell wall/membrane components such as sphingolipids and oxylipins may contribute to determining the fate of host-pathogen interactions.Therefore, the question-"Does fumonisin alter plant lipidome or does plant lipidome modulate fumonisin accumulation?"-is still open.

ABSTRACT
Lipid molecules are increasingly recognized as signals exchanged by organisms interacting in pathogenic and/or symbiotic ways. Some classes of lipids actively determine the fate of the interactions. Host cuticle/cell wall/membrane components such as sphingolipids and oxylipins may contribute to determining the fate of host-pathogen interactions. In the present field study, we considered the relationship between specific sphingolipids and oxylipins of different hybrids of Zea mays and fumonisin by F. verticillioides, sampling ears at different growth stages from early dough to fully ripe. The amount of total and free fumonisin differed significantly between hybrids and increased significantly with maize ripening. Oxylipins and phytoceramides changed significantly within the hybrids and decreased with kernel maturation, starting from physiological maturity. Although the correlation between fumonisin accumulation and plant lipid profile is certain, the data collected so far cannot define a cause-effect relationship but open up new perspectives. Therefore, the question-"Does fumonisin alter plant lipidome or does plant lipidome modulate fumonisin accumulation?"-is still open.

Fusarium spp. incidence (%) in naturally contaminated maize kernels from four commercial hybrids (17–20) harvested at four different growth stages: at early dough maturity (GS1), dough stage (GS2), physiological maturity (GS3) and fully ripe (GS4) in three locations in Italy. Results represent the mean of n = 9 incidence values deriving from the three different locations (biological replicates) in three technical replicates ± SE.

Results represent the mean of n = 9 incidence values deriving from the three different locations (biological replicates) in three technical replicates ± SE.

Mentions: The incidence of kernels infected by Fusarium spp. significantly increased during the four growth stages (p < 0.001; Table 1). Notably, at GS4, hybrid 17 was found to be by far the most contaminated and hybrid 18 the least contaminated by Fusarium spp. (Mann Whitney Test; p < 0.01) (Figure 1).
