The study of benzidine peroxidase activity of tomato (Solanum lycopersicum L.) varieties under drought conditions followed by recovery
2022
Drought is one of the most severe conditions that limit the growth and productivity of plants. This issue is important when considering economically relevant crops, including tomato plants. Therefore, research into the effects of drought on tomato plants is critical. The antioxidant system is known to play a key role in plant responses to drought. The benzidine peroxidase (BPO, EC 1.1.11.1.7) activity and its isoenzyme spectrum have been studied in ten local tomato varieties (Elim, Azerbaijan 94, Nuru, Ilyas, Yubiley 60, Mirvari, Zarrabi, Elnur, Khazar, Shakar). The benzidine peroxidase activity was found to increase in all studied genotypes under drought compared to the control variants. However, the activity of benzidine peroxidase decreased significantly in all varieties except the Elim variety after 3 days and 7 days of rehydration. Furthermore, it was determined 5 isoforms of BPO for the Khazar Elnur, Nuru, Miravari, Ilyas, and Yubiley 60 genotypes, 4 isoforms for the Elim genotype, and 3 isoforms for the Azerbaijan-94 genotype.
