| Outline of Final Research Achievements |
Cationic cell-wall-bound peroxidase (CWPO-C), a class III peroxidase in Populus alba, has been considered to play a role in the lignification process. In order to promote better understanding about CWPO-C functions, detailed expression analysis of this peroxidase using laser microdissection and expression quantification tools were performed. It was shown that cells express CWPO-C in cortex cells, instead of cambium cells. Moreover CWPO-C expression was observed in apical meristem. In addition, delay of the growth and decrease of branch number were observed in transgenic Arabidopsis overexpressing CWPO-C. These results imply that CWPO-C is involved in growth and cell elongation; suggesting a new aspect to the role of CWPO-C.
