Characterization of organelle DNA degradation mediated by DPD1 exonuclease in the rice genome-edited line.

Plant molecular biology - 10 Jun 2024

Abstract excerpt

Mitochondria and plastids, originated as ancestral endosymbiotic bacteria, contain their own DNA sequences. These organelle DNAs (orgDNAs) are, despite the limited genetic information they contain, an indispensable part of the genetic systems but exist as multiple copies, making up a substantial amount of total cellular DNA. Given this abundance, orgDNA is known to undergo tissue-specific degradation in plants....
