Can Green Algal Plastid Genome Size Be Explained by DNA Repair Mechanisms?

Genome biology and evolution - 1 Feb 2020

Smith David Roy

Abstract excerpt

A major finding in organelle biology over the past decade is that land plant mitochondrial genomes, which are the largest among eukaryotes, can have a "Jekyll and Hyde" mutational pattern: low for synonymous sites, high for intergenic ones. This has led to the theory that double-strand breaks (DSBs) in the intergenic DNA of plant mitogenomes are repaired by inaccurate mechanisms, such as break-induced...
