Been working on a really strange retron bacterial immune system, here's the preprint: www.biorxiv.org/content/10.1...
Type VI retrons are unlike any other. Phage infection triggers reverse transcription of a DNA fragment that activates translation of a toxin to kill the infected cell.

Since there are so many copies of the mtDNA per cell, each cell carries its own analog recording where a weak signal leads to a small percentage of edited mtDNA and a strong signal leads to a high percentage. Can be prepped and read out along with transcriptomes using a 10x workflow. (more below)

Check out MitoScribe in our new preprint led by Linhan Wang: www.biorxiv.org/content/10.1...
It's an analog molecular recorder that uses neutral base edits to the mitochondrial genome to store information about historical signaling in a cell. Single cell resolution at scale (see next post)!
