M. aPhysiological Responses of Maize Leaves Exposed to Ethylene and Infected by Exserohilum turcicum.h[electronic resource] c2025 aThe hormone ethylene (ET) plays multiple roles in plant growth and development. However, its involvement in the maize?Exserohilum turcicum interaction must be better elucidated. This study investigated the role of ET in the infection process of E. turcicum on maize leaves at the physiological (leaf gas exchange and chlorophyll a fluorescence parameters and concentrations of photosynthetic pigments) and biochemical [concentrations of malondialdehyde (MDA), hydrogen peroxide (H2O2) and superoxide anion radical] levels. Plants were sprayed with water (control), ET or aminooxyacetic acid (AOA) (an inhibitor of ET production) and challenged or not with E. turcicum. ET was not detected in the infected leaves of ET- or AOA-sprayed plants compared to noninfected leaves exposed to ET.
