2 unusual facts about nuclear DNA


Lavasoa dwarf lemur

The Lavasoa dwarf lemur, named for the Lavasoa Mountains in southern Madagascar, became the sixth known species in 2013 when it was differentiated from the furry-eared dwarf lemur (C. crossleyi) through analyses of mitochondrial and nuclear material performed by a team of German and Malagasy researchers.

Thomasomys

Nuclear DNA sequence analysis has indicated that it is a sister taxon to Rhagomys.


Catharus

Comparison of mtDNA cytochrome b and NADH dehydrogenase subunit 2 as well as nuclear β-fibrinogen intron 7 sequence data indicates that this is incorrect (Winker & Pruett, 2006).

Nesoenas

Recent cladistic analysis of mtDNA cytochrome b, cytochrome c oxidase subunit I and NADH dehydrogenase subunit 2, as well as nuclear β-fibrinogen intron 7 sequence data, combined with a distinct morphology and behaviour, suggest that the genus is valid but not monotypic.

Patagioenas

There are 17 species of Patagioenas, which can be assigned to 4 groups based on mtDNA cytochrome b, cytochrome c oxidase subunit I, and NADH dehydrogenase subunit 2, as well as the nuclear β-fibrinogen intron 7 data combined with analyses of vocalizations and morphology.

C-value enigma

The term "C-value enigma" represents an update of the more common but outdated term "C-value paradox" (Thomas 1971), being ultimately derived from the term "C-value" (Swift 1950) in reference to haploid nuclear DNA contents.

Chronic progressive external ophthalmoplegia

One study showed that mtDNA deletion seen in CPEO patients also had an associated nuclear DNA deletion of the Twinkle gene which encodes specific mitochondrial protein; Twinkle.

Homo

The nuclear DNA results indicate about 30% of derived alleles in H. sapiens are also in the Neanderthal lineage.

Maluridae

A 2011 analysis by Amy Driskell and colleagues of mitochondrial and nuclear DNA found the Broad-billed Fairywren and Campbell's Fairywren to lie in a clade with the two other monospecific New Guinea genera and not with the other species of Malurus.

Mary-Dell Chilton

She was the first (1977) to demonstrate the presence of a fragment of Agrobacterium Ti plasmid DNA in the nuclear DNA of crown gall tissue.
