MSH1 is required for maintenance of the low mutation rates in plant mitochondrial and plastid genomes.

Proceedings of the National Academy of Sciences of the United States of America - 14 Jul 2020

Abstract excerpt

Mitochondrial and plastid genomes in land plants exhibit some of the slowest rates of sequence evolution observed in any eukaryotic genome, suggesting an exceptional ability to prevent or correct mutations. However, the mechanisms responsible for this extreme fidelity remain unclear. We tested seven candidate genes involved in cytoplasmic DNA replication, recombination, and repair (POLIA, POLIB, MSH1, RECA3, UNG,...
