Single-celled protists in the guts of animals thrive without mitochondria, study finds

Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria, which generate chemical energy using oxygen.

The #symbioses that gave rise to primary #organelles are key events in the origin of #Eukaryotes. @PierreSGarcia @FredBarras & @SGribaldo use markers from 2 conserved machineries for [Fe-S] cluster biogenesis to support an early emergence of #mitochondria & #plastids within #Alphaproteobacteria & #Cyanobacteria #PLOSBiology https://plos.io/3FNP5E5

Components of iron–Sulfur cluster assembly machineries are robust phylogenetic markers to trace the origin of mitochondria and plastids

The symbioses that gave rise to primary organelles are key events in the origin of Eukaryotes. This study uses a dataset of markers belonging to two conserved machineries responsible for [Fe-S] cluster biogenesis to support an early emergence of mito…

"They propose that early protoeukaryotes were predators, relying on bacterial prey. These bacteria, in response to predation, produced toxins as a defense mechanism. Over time, these bacteria were domesticated to serve as mitochondria within eukaryotic cells, and their toxins evolved into apoptotic factors. "

High school didn't teach you how to do your taxes, how to negotiate pay, or the value of creativity, but I bet all of you learned that THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL.

Let's talk about what you SHOULD have learned about the #mitochondria.

Did you ever wonder about the physiological, ecological, and evolutionary consequences of a low energy-yielding metabolism in anaerobic eukaryotes? I attempted to provide an answer in this essay: https://rdcu.be/c3xJa

To all #mitochondria enthusiasts out there: we just released mitoMouse, a metabolic model for mouse mitochondria. It is based on the well-known and detailed human MitoCore model, which we updated with latest knowledge on the CoQ crossroad; and translated to SBML3 and Jupyter for easy usage. mitoMouse has 390 genes and 445 metabolites involved in 560 unique reactions. Find here our preprint with all details: https://www.biorxiv.org/content/10.1101/2023.01.02.522468v1
Feedback and collaborations are welcome!

MitoMouse is a model reconstruction of murine mitochondrial metabolism

Mitochondria, apart from being the powerhouses of our cells, are key players in cellular metabolism and homeostasis.
