Role of intercompartmental DNA transfer in producing genetic diversity.

International review of cell and molecular biology - 1 Jan 2011

Leister Dario, Kleine Tatjana

Abstract excerpt

In eukaryotic cells, genes are found in three compartments-the nucleus, mitochondria, and plastids-and extensive gene transfer has occurred between them. Most organellar genes in the nucleus migrated there long ago, but transfer is ongoing and ubiquitous. It now generates mostly noncoding nuclear DNA, can also disrupt gene functions, and reshape genes by adding novel exons. Plastid or nuclear sequences have also...
