Kosakyan et al. sequenced mitogenomes of species from the two main lineages of the Gastrotricha; they found stable mitogenomes in the mostly freshwater Chaetonotida, but a dynamic pattern in the the marine Macrodasyida.

Aufgrund statistischer Analysen der mitochondrialen #DNA (#mtDNA) des Homo sapiens wird angenommen, "dass es vor rund 70.000 bis 80.000 Jahren einen genetischen Flaschenhals beim Menschen gegeben haben könnte; seinerzeit hätten demnach nur etwa 1.000 bis 10.000 Individuen von Homo sapiens, größtenteils in Afrika, gelebt."
😳
Den heutigen prozentualen Anteil an Vollidioten vorausgesetzt, konnte sich der " okay-e" Teil der Menschheit zu dieser Zeit in einer Hütte treffen...

🥂 🐌 First paper out from our Cuba-UK collaboration 🐌🥂. We used mtDNA and rRNA sequences to place beautiful Polymita snails in a phylogeny. Basically, they are basal to a whole bunch of other important and diverse snail groups. https://academic.oup.com/mollus/article/91/2/eyaf006/8173425
There's an obvious #paperthemetune, the "Polymita song", by collaborator Norvis Hernandez and others. https://youtu.be/1srl4_JI_Fs?si=G3Z5bVLCDWR554nl #snails #mtDNA #phylogenetics #UoN

“Variation of the mitochondrial genome has been also studied as possible source of incomplete penetrance. In fact, constitutive variants defining mtDNA haplogroup J have been found to increase penetrance in families with the m.11778G>A and, more consistently, with the m.14484T>C mutations.” #dna #isogg #mtdna #mitochondrial #haplogroupj

New 🐌 paper alert! We showed that snails with v. few mtDNA copies per nuclear genome (<10) have a v. high rate of heteroplasmy; heteroplasmy is inherited through the germline, albeit with selection against synonymous mutations. We also found that some mtDNA genomes have tRNAs that are repeated up to 24 times! https://doi.org/10.1186/s12864-024-10505-w

Just read this, https://www.pnas.org/doi/10.1073/pnas.2317240121, that extraordinary high rate of mtDNA evolution in some plants is associated low mtDNA copy number. Lower Ne is the obvious explanation - but the authors instead put fwd homologous recombination, because it is less effective in low copy number environments. More complicated explanation, with no direct evidence? Thoughts?
