Arabidopsis thaliana organellar DNA polymerase IB mutants exhibit reduced mtDNA levels with a decrease in mitochondrial area density.

Physiologia plantarum - 1 Sept 2013

Cupp John D, Nielsen Brent L

Abstract excerpt

Plant organelle genomes are complex and the mechanisms for their replication and maintenance remain unclear. Arabidopsis thaliana has two DNA polymerase genes, DNA polymerase IA (polIA) and polIB, that are dual targeted to mitochondria and chloroplasts and are differentially expressed in primary plant tissues. PolIB gene expression occurs at higher levels in tissues not primary for photosynthesis. Arabidopsis...
