| Research Abstract |
In this study, I tried to establish the haploid breeding method using kinetochore malfunction lines. First, plants expressing GFP::CENH3 (centromere specific histone H3) were made by transformations using Arabidopsis, tobacco and tomato for the purpose. Next, RNAi constructs to knock down internal CENH3 were transformed to the plants. Some transformants having these constructs were isolated but expression levels of internal CENH3 in the transformants were as same as these in wild type. These results suggested that RNAi method is not sufficient for the purpose.
