| Outline of Final Research Achievements |
The candidate genes for extracellular monolignol transport were screened. Tracheary element (TE) induced cells in which lignification is promoted was employed. Besides, different plant organ samples, which has different lignification were also applied. The expression analysis of the transporter genes in these samples was performed. Secondary wall formation and lignin synthesis related genes were also subjected to the analysis as references. Expression profile with TE differentiated samples showed four transporter genes highly expressed synchronously with reference genes. Besides, five transporter genes from plant organ analysis were also screened as candidates. There was no significant change in the amount of lignin in the single gene knockout mutant of the candidates. The expression levels of two other candidates were largely promoted in the single gene knockout plant, suggesting that these transporter candidates were functionally redundant.
