… a Lys for a conserved Pro residue in the ATP binding/hydrolyzing P-loop, (2) a Lys-to-Pro
substitution in the RecA signature motif involved in monomer–monomer interaction, and (3) a C

Substoichiometric shifting in the plant mitochondrial genome is influenced by a gene homologous to MutS

…, R Yule, A Elo, AC Christensen… - Proceedings of the …, 2003 - National Acad Sciences
The plant mitochondrial genome is retained in a multipartite structure that arises by a process
of repeat-mediated homologous recombination. Low-frequency ectopic recombination also …

[HTML][HTML] The alternative reality of plant mitochondrial DNA: One ring does not rule them all

…, ME Schranz, RW Michelmore, AC Christensen - PLoS …, 2019 - journals.plos.org
Plant mitochondrial genomes are usually assembled and displayed as circular maps based
on the widely-held view across the broad community of life scientists that circular genome-…

Diversity of the Arabidopsis mitochondrial genome occurs via nuclear-controlled recombination activity

…, V Shedge, J Davila, AC Christensen… - Genetics, 2009 - academic.oup.com
The plant mitochondrial genome is recombinogenic, with DNA exchange activity controlled
to a large extent by nuclear gene products. One nuclear gene, MSH1, appears to participate …

Plant mitochondrial genome evolution can be explained by DNA repair mechanisms

AC Christensen - Genome biology and evolution, 2013 - academic.oup.com
Plant mitochondrial genomes are notorious for their large and variable size, nonconserved
open reading frames of unknown function, and high rates of rearrangement. Paradoxically, …

Reappraisal of the human ocular growth curve in fetal life, infancy, and early childhood.

HC Fledelius, AC Christensen - British Journal of Ophthalmology, 1996 - bjo.bmj.com
AIMS: The aim of this study was to find an algorithm of better fit for early eye growth than the
linear regression usually advanced. METHODS: The analysis is based on previously …

Repeats of unusual size in plant mitochondrial genomes: identification, incidence and evolution

EL Wynn, AC Christensen - G3: Genes, Genomes, Genetics, 2019 - academic.oup.com
Plant mitochondrial genomes have excessive size relative to coding capacity, a low
mutation rate in genes and a high rearrangement rate. They also have abundant non-tandem …
