I study evolutionary bioenergetics, focused mainly on mitochondrial physiology (especially AOX) and mitonuclear interactions.

Here's our take on it when it comes to color signals : doi.org/10.1098/rstb...

+1 'for don't call it moots', but also I grow brine shrimp and Tigriopus copepods and think about them sometimes.

Oooh, I look forward to reading this!

Yeah, maybe heteroplasmy of mitos and the oogenesis bottleneck still allows for the light of selection to shine on bad mitogenomes. Not the case in Y?

.... because mito genome products must closely interact with nuclear products for mitos to function. So, mitonuclear coevolution and selection for functional mitochondria.

I don't think about Y much, but are they still thought to mostly be degenerate?

I'm Ryan Weaver (EEOB, Iowa State University). I am recruiting PhD. students to work on topics related to mitochondrial evolutionary bioenergetics. Potential projects include mitonuclear coevoution and the bioenergetic basis of pathogenicity of animal-infecting fungi, among others.

Here are the instructions I gave. I used the custom instructions section in GPT to try to control how it behaved. We used GPT3.5 since its free, but I think 4.0 would have performed better. GPT3.5 was kind of a pushover, confidently agreeing with incorrect answers and carried those mistakes forward

In addition to clarifying presence/absence in some taxa, we found putative cases of horizontal AOX transfer from fungi and protists to some animal taxa. We’re working on the why, but the hgt AOX taxa tend to inhabit hypoxic environments, a potential role for AOX to maintain mito function.

AOX is an alternative to complex IV, which is a terminal oxidase. AOX provides metabolic flexibility for when conditions disrupt CIV function. E.g. hypoxia, redox stress. We show it is present in extant proteobacteria, the group thought to be the source of mitos in eukaryotes, but not other bacteria
