| Summary: | The objective of the present investigation was to identify the effect of
antimycin A (AA) as an activator of the alternative pathway (AP) of
respiration, on oxidative stress intensity, the level of lipid peroxidation
(LPO) and activities of H2O2 scavenging enzymes in functionally different
organs of Triticum aestivum L. subjected to short- and long-term exposure to
high temperature (HT). The level of LPO was assessed in terms of
malondialdehyde (MDA), an indicator of oxidative injury. The results
demonstrated increases in the total content of reactive oxygen species (ROS)
and MDA production in developing and senescent organs of wheat seedlings, and
significant augmentation of the activities of the antioxidant enzymes,
catalase and ascorbate peroxidase, in different organs in response to
exposure to HT. The activation of the AP by AA restrained ROS production in
the mitochondrial electron transport chain (mETC) under exposure to HT. |
