“…Phenyl, aryl, aliphatic rings, and aliphatic chain, often containing hydroxylated functionalities, can be bound to the parent phenolic ring (Figure 3). They contribute to various traits, such as pigmentation and resistance to pathogens in plants [132][133][134], and are generally present in food, spices, or food preservatives or belong to the list of generally recognized as safe (GRAS) compounds [135].…”

Fusarium spp. are ubiquitous fungi able to cause Fusarium head blight and Fusarium foot and root rot on wheat. Among relevant pathogenic species, Fusarium graminearum and Fusarium culmorum cause significant yield and quality loss and result in contamination of the grain with mycotoxins, mainly type B trichothecenes, which are a major health concern for humans and animals. Phenolic compounds of natural origin are being increasingly explored as fungicides on those pathogens. This review summarizes recent research activities related to the antifungal and anti-mycotoxigenic activity of natural phenolic compounds against Fusarium, including studies into the mechanisms of action of major exogenous phenolic inhibitors, their structure-activity interaction, and the combined effect of these compounds with other natural products or with conventional fungicides in mycotoxin modulation. The role of high-throughput analysis tools to decipher key signaling molecules able to modulate the production of mycotoxins and the development of sustainable formulations enhancing potential inhibitors’ efficacy are also discussed.

“…Plant cells show physiological and biochemical responses to physical, chemical, and microbial agents known as "elicitors". Elicitation is the process of inducing or stimulating the biosynthesis of phytomolecules by plant cells to ensure their viability and competitiveness [21]. Biotic and abiotic elicitors have been employed in plant tissue culture system to induce and improve different secondary metabolites production by reducing the time required to increase culture biomass to achieve high productivity [10,[22][23][24].…”

Echinacea (Echinacea purpurea L. Moench) is one of the most important medicinal plants worldwide with various pharmacological properties. In the current study, a biotic elicitation strategy using the fungal elicitors yeast extract (YE), Aspergillus niger and Fusarium oxysporum was employed to improve the productivity of callus biomass, total phenolics and total flavonoids in E. purpurea leaf-derived callus. Significant differences were recorded between biotic elicitors concerning callus production, total phenolics and flavonoids accumulation, DPPH scavenging activity, and antioxidant enzymes activity. Callus biomass, growth index, and relative growth rate were significantly enhanced in the elicited cultures. The highest content of total phenolics was recorded with 4 g/l YE, 1 g/l A. niger or 0.25 g/l F. oxysporum. However, 0.25 g/l of F. oxysporum was superior in enhancing the productivity of total phenolics, and the content and productivity of total flavonoids, representing 310.60%, 361.40%, and 649.50% increase of control, respectively. In general, callus extracts exhibited 79.02 -89.51% scavenging activity of DPPH comparing with ascorbic acid (97.91%). YE at 4 g/l recorded the highest activity of catalase (CAT) and peroxidase (POD) enzymes. However, adding A. niger or F. oxysporum have a superior effect on polyphenol oxidase (PPO) activity. The current study revealed the possibility of using callus cultures and biotic elicitation as a promising tool for the in vitro production of phenols and flavonoids phytoconstituents with high antioxidant capacity from the high-value medicinal plant E. purpurea.
