Scholarcy highlights

  • The free-radical theory of ageing originated in the medical sciences more than half-a-century ago
  • ROS metabolism needs to be studied during all stages of development maturation drying, the ascorbate system may play a central role in embryogenesis and cell growth mainly because ascorbate may control cell-cycle progression and/or totipotency of plant protoplasts has been related to the activity of the cell antioxidant machinery since a direct correlation exists between high AOS content and repressed expression of totipotency
  • AOS and antioxidants probably play a wider role in seed physiology than is currently appreciated as illustrated by the studies reviewed elsewhere and/or here
  • Many questions related to the roles of AOS in seed physiology have to be addressed
  • Progress is required in determining their cellular production sites and/or their diffusion within the cell taking into account the unique aspects of seed tissue physiology in particular the dramatic changes in moisture content and metabolic activity that occur in the life of the seed
  • Elucidating the mechanisms underlying the interplay of AOS with hormones is a challenge for future research in this area. Such investigations will without any doubt encourage revisiting the cellular mechanisms involved in acquisition of the desiccation tolerance, germination and alleviation of dormancy
