Research Abstract

We showed that mixoploidy is inherited in the transgenic tobacco, and analyzed epigenetic status at a chromosomal level. We also performed FISH and sequencing analyses of mixoploid plants with tobacco BAC clones. From these analyses, we discussed the mechanisms of producing mixoploidy in the tobacco, which might be related to the epigenetic status at chromosomal and DNA levels.
