A new paper with big news in the world of red carotenoid ornamentation: House Finches do not utilize CYP2J19/BDH1L to produce red feather pigments. Why is this big new?...(1/6)

An ISU research team has created organoids from turtle livers, the 1st-ever turtle organoids. The discovery will speed up turtle genetic research, including traits with potential human benefit such as resistance to oxygen deprivation. #IowaStateInnovates

Anytime I talk about extreme rate variation in plant mtDNA evolution, people ask why some lineages evolve fast. @KendraZwonitzer took that personally. Her paper out today @PNAS offers some evidence for one possibility.

Our great work led by the Schumer lab is finally out @Nature This is some of the best evidence out there that mitonuclear interactions can lead to speciation.

Sex determination is incredibly varied! In this new paper led by @Texas_Mussels, we find a small RNA encoded in the mtDNA of male (not female) bivalves may interact with nuclear genes to determine sex. More work is needed, but weird nonetheless...

.@AEMcDonaldWLU and I have a new paper out reviewing the wide taxonomic distribution of an understudied aspect of mitochondrial physiology, the alternative oxidase AOX. We update, clarify, and correct the record of which taxa encode AOX in their genomes.

Why such a low-tech approach? 1stbecause it works. 2nd because we hope to increase AOX awareness of researchers who might be put off by model-based tools (which we also used) to help them determine if their critter of interest has AOX.

We also highlight cases of sequence contaminants that falsely attribute AOX sequences to taxa that do not have them. But the thing I’m most jazzed about is putative repeated independent horizontal gene transfer of AOX into metazoan genomes from fungi and protists.

Knowing amino acid identities at positions up and down stream of IBSs can discern between bacterial vs fungal, protist vs metazoan, etc with good certainty. We created a flowchart to facilitate this.

We analyzed AOX seqs we collected over the past decade from across the tree of life and after 100s of hrs staring at seq alignments, some patterns emerged. Sequence motifs around 4 strictly conserved iron-binding sites tend to be diagnostic to the phylum level or lower.
