Senescence of leaves is characterized by a gradual decline in protein-content. At the initial stage of protein breakdown, oat leaves, attached to the plant, do not exhibit an increase in protease activity, indicating that synthesis of additional protease is not required for protein degradation (Van Loon et al., 1986).
