This spin restriction makes O prefer to 2 accept its electrons one at a time, leading to the generation of the so-called reactive oxygen species (ROS). The chLaconic 发表于 2025-3-26 00:51:12

These processes occur as a part of developmental activities such as aging and/or under influence of biotic and abiotic stress like pathogenic attack and emonologue 发表于 2025-3-26 11:05:51

Rudolf Martys responses and development in plants. While properly controlled amounts of ROS function as signaling molecules, excessive accumulation of ROS can cause undesirable side effects due to their ability to oxidize DNA, lipids, and proteins. To limit the damaging consequences of unrestricted ROS accumula
