| Research Abstract |
Coniferin was actively transported into vacuole in the presence of ATP in early stage of secondary wall formation in poplar and Japanese cypress. Coniferin accumulated in vacuole gradually decreased in later stage of secondary wall formation. We collected the Arabidopsis seeds in which T-DNA was inserted to the candidate gene involved in monolignol transportation, and grew them for 10 to 12 weeks. Then we investigated the lignin distribution in interfasicular fibers of stalk. One of the transformants showed low syringyl lignin content in the secondary wall of interfasicular fibers.
