Ordered genome change of plant and animal body cells revealed by the genome profiling method

摘要

In the past, it was widely thought that, although epigenetically different, the genome sequences of cells are basically the same in a single body. In retrospect, the genome-uniformity idea may have been naive, considering that DNA polymerases cannot be perfect. Here, a systemic, not sporadic, genome change was demonstrated in a single plant (Arabidopsis) and animal (zebrafish) body using genome DNAs taken in an ordered manner using the genome profiling method. This can be explained because mutations accumulate additively in progeny cells, and these results are critically significant for developmental and oncological research.
