The expression of human lysozyme in mature seed of T₀ transgenic plants. Seeds of 30 plants containing the Reb and lysozyme genes and seeds from 17 plants containing only the lysozyme gene were analyzed for lysozyme activity. The lysozyme gene was under the control of the Glb promoter, and the Reb gene was under the control of its own promoter. Individual seeds from each plant were analyzed. Transgenic seeds lacking detectable amounts of lysozyme were excluded. The activities of 20 lysozyme-positive seeds per plant, including both hemizygous and homozygous seeds, were averaged and plotted on the graph.
