Reactive oxygen species and seed germination
WebJun 27, 2024 · Seed germination is a critical step in the life cycle of higher plants. During germination, viable seeds develop into plants upon imbibition in water, which then allows for embryo growth until the radicle breaks through the peripheral tissue structures (endosperm and seed coat; Bewley et al., 2013). WebReactive oxygen species (ROS) plays a wide role in all stages of plant growth and development. Recent reports suggest that ROS plays a major role in the fusion of male …
