Outline of Final Research Achievements

To clarify the mechanisms of secondary cell wall (SCW) formation during xylem vessel differentiation, we have screened the chemicals which affect the SCW formation. As a result, we could identify a compound sulfamethizole (SMZ), which had a novel bioactivity to induce abnormal branching and bending in spiral protoxylem SCWs. SMZ induced aberrant branching and bending cortical microtubules specifically during vessel cell differentiation, meaning that SMZ is a novel inhibitor against SCW formation mechanism in protoxylem and that SMZ could be an novel tool to investigate it further.
