12/ Unlike snowflake yeast, where one mutation hands you collective reproduction, here selection on collectives builds heredity. A slick model for how genes became chromosomes and endosymbionts became organelles. @charly-evos.bsky.social @paulbrainey.bsky.social doi.org/10.64898/2026.08.05.743067
Post anzeigen11/ The mechanism is beautiful. Red and green fused with the yeast's native 2µ plasmid into a single replicon, and both lines independently knocked out FLP1, the recombinase that would otherwise cut the chimera back apart. Restore Flp1 and heredity collapses.
Post anzeigen9/ This next one is super cool. How do unrelated replicators fuse into one heritable unit? Hernandez-Beltran, McConnell, Rogers & Rainey built one from scratch: red and green plasmids in yeast, with selection for yellow cells carrying both.
