DNA transfer from chloroplasts and mitochondria to the nucleus is ongoing in eukaryotes but the mechanisms involved are poorly understood. Mitochondrial DNA was observed to integrate into the nuclear genome through DNA double-strand break repair in Nicotiana tabacum. Here, 14 nuclear insertions of chloroplast DNA (nupts) that are unique to Oryza sativa subsp. indica were identified. Comparisons with the preinsertion nuclear loci identified in the related subspecies, O. sativa subsp. japonica… CONTINUE READING
