Part of ongoing study to reduce the lignin content in aspen trees by isolating the lignin biosynthesis genes via antisense RNA methods focused on peroxidase genes from the hybrid aspen (Populus kitakiemensis). The transgenic poplars had lower total peroxidase activity than that of the control. Peroxidase isozyme analysis established that the transgenic trees had no peroxidase band. Lignin content in the transgenic trees was 40-80 percent less than in the control. The amount of glucose increased 5-10 percent. The chemical structure of the lignin had fewer units of p-hydroxyl, guaiacyl, and syringyl. Results confirmed transgenic poplar trees having higher cellulose contents. 9 refs.
