| Research Abstract |
Artificial mircoRNA (amiRNA) was designed using the precursor sequence of the endogenous soybean miRNA to suppress the expression of target gene efficiently in soybean plants. The constructed amiRNA precursor contains a complementary sequence to the transcript of target gene. Transgenic soybean plants expressing the amiRNA were generated to suppress the gene expression of seed storage protein. The expression of these genes and accumulation of storage protein were significantly decreased in seeds of transgenic soybean. In addition, the function of glycosyltransferase gene for DDMP saponin, which is known to be one of functional chemical compounds in soybean seeds, was characterized by the amiRNA expression system. I demonstrated that the knock-down system established in this study was useful for the functional analysis of genes in soybean plant.
