Methyl jasmonate alleviated the adverse effects of cadmium stress in pea (Pisum sativum L.): A nexus of photosystem II activity and dynamics of redox balance

Popis výsledku v původním jazyce

The accumulation of cadmium (Cd) in leaves reduces photosynthetic capacity by degrading photosynthetic pigments, reducing photosystem II activity, and producing reactive oxygen species (ROS). Though it was demonstrated that the application of Methyl Jasmonate (MeJA) induces heavy metal (HM) stress tolerance in plants, its role in adjusting redox balance and photosynthetic machinery is unclear. In this study, the role of MeJA in modulating photosystem II (PSII) activity and antioxidant defense system was investigated to reduce the toxic effects of Cd on the growth of pea (Pisum sativum L.) cultivars. One week old seedlings of three pea varieties were subjected to Cd stress (0, 50, 100 mu m), and MeJA (0, 1, 5, 10 mu m) was applied as a foliar spray for 2 weeks. Cadmium stress reduced the growth of all three pea varieties. Cadmium stress decreased photosynthetic pigments Chl a (58,15 percent), Chl b (48,97 percent), total Chl (51,9 percent) and carotenoids (44,01 percent) and efficiency of photosystem
