Research Abstract

We focused on the molecular mechanisms of endoreduplication controlled by chloroplast. Because two genes relating chloroplast were identified as the corresponding genes of dominant mutants, ilp2-D and ilp5-D that shows increased polyploidy. To examine physiological function of these genes, we analyzed loss of these genes mutants. However, these mutants did not showed significant phenotypes on polyploidy levels.
We newly developed a unique construction of RNAi for the knock-down of these genes, and published a paper describing several advantage points of this method.
