Research introduction

“Comparison of mutation frequencies among plants produced by genome editing technology and conventional breeding methods.”
  • (This work was supported by Cabinet Office, Government of Japan, Cross-ministerial Strategic Innovation Promotion Program (SIP), “Technologies for creating next-generation agriculture, forestry and fisheries” (funding agency: Bio-oriented Technology Research Advancement Institution, NARO)
    Genome editing technology that can induce mutations and insert genes to targeted site on genome, has developed rapidly in recent years. In this research, we will compare the mutation frequency on whole genome sequence among plants produced by genome editing technology, genetically modified technology, tissue culture technology, and its wild type. This research aims to contribute to the risk assessment and acceptance of the social license in application of new plant breeding technology.

“Elucidation of reproductive isolation mechanism between volunteer oilseed rape and genetically modified oilseed rape in sympatric area in Japan”
  • (This work was supported by JSPS KAKENHI Grant-in-Aid for Young Scientists (Start-up), Grant Numbers JP 18H06007)
    The oilseed rape was introduced to Japan in the late 1,800’s and is mainly used for oil production. Currently, genetically modified (GM) crops with various characteristics are developed, and about 2 million tons of GM oilseed rape are annually imported to Japan. GM oilseed rape imported to Japan had the approval for no environmental risk on biodiversity in Japan. According to long-time monitoring by the Ministry of Agriculture, Forestry and Fisheries, volunteer GM oilseed rape plants in Japan have not increased through escape the imported seeds since started commercialization. We indicated that there was no introgression between GM oilseed rape and volunteer oilseed rape byo polymorphism analysis. We assume that the cause of that introgression has not been confirmed between GM oilseed rape and volunteer oilseed rape is due to some reproductive isolation mechanisms. Therefore, we try to elucidate the reproductive isolation mechanisms.
