Endoreduplication (or endocycle) is a modified cell cycle, that widely seen among multicellular organisms such as plants and animals. In plants, endoreduplication is under developmental or environmental controls and results in extensive increase of cell volume and therefore affects plant body size. Arabidopsis thaliana, the most widely studied model plant, exhibits endoreduplication in nearly all organs at high levels, and thus is a useful material to study the biological significance and molecular mechanisms of endoreduplication. In this review, I will overview the present understandings of the endoreduplication in Arabidopsis, with a special emphasis on the generality of this biological process.
