Work led by @pbentz.bsky.social shows that two of eight dispersals of Asparagus out of Southern Africa were associated with shifts to dioecy and independently evolved XY sex determination systems.

Analyses of a new genomes for garden asparagus and a Mediterranean basin congener reveal independent origins of dioecy and XY sex chromosomes. The work led by Phil Bentz @pbentz.bsky.social finds no overlap in the two Y-linked sex-determination genes - www.biorxiv.org/content/10.1... .

I love this trend in polyploid research:

“With new data and techniques, we can finally tackle this horribly complicated group!”

“And guess what? It’s even worse than we imagined!”

But seriously, excellent work!
