| Outline of Final Research Achievements |
Ascorbic acid is an antioxidant, which is abundantly contained within the plant cell, and plays important roles in plants. Plants have some pathways for ascorbic acid biosynthesis. The mechanism for biosynthesis regulation of plant ascorbic acid attracts so much attention.
Acerola (Malpighia glabra L.) is one of the richest known natural sources of ascorbic acid (vitamin C). Thus, the gene expression of ascorbic acid-biosynthetic enzymes is markedly high in acerola. Molecular mechanism of the high expression of the ascorbic acid biosynthetic enzyme gene became clear partially. Acerola genes for ascorbic acid-biosynthetic enzymes were introduced and over-expressed to generate transgenic plants containing a large amount of ascorbic acid. Finally, this research will lead to generation of stress-resistant transgenic plants with high ascorbic acid contents.
