Cím:	Cyclic hydroxamic acids as stress metabolites in biotic stresses / Péter Makleit
Dátum:	2023
Megjegyzések:	Cyclic hydroxamic acids are secondary metabolites of Poaceae species. These chemical compounds have diverse physiological roles. Stress metabolite function is their elemental task. The aim of the research was to establish the effect of a plant pathogen fungus and/or a pest on the cyclic hydroxamic acid content of two different wheat cultivars. At the age of 3 weeks, wheat plants (cultivars Hystar and KG Vitéz) were inoculated with Fusarium graminearum conidia and at the same time Oulema melanopus larvae were placed to the plants. Treatments were applied separately and in combination. Control plant were not infested. The cyclic hydroxamic acid content was determined after 1 and 2 weeks of inoculation/infestation. Fusarium inoculation significantly increased the Hystar hybrid's cyclic hydroxamic acid content compared to the control, from 104.34 mg kg-1 fresh weight to 145.78 mg kg-1 fresh weight respectively. On the other hand the cyclic hydroxamic acid content of KG Vitéz was significantly higher on time of second sampling compared to Hystar hybrid. The elevated level of cyclic hydroxamic acids support plants to overcome the negative effects of pathogens and pests. Plants with higher cyclic hydroxamic acid content can better prevent themselves from different biotic stressors.
