Is loss of distyly always associated with high selfing rates? And what are the genomic consequences? Read more about this in our new preprint on repeated loss of distyly in Linum, led by @zopos.bsky.social and @panazerv.bsky.social www.biorxiv.org/content/10.6...

An angiosperm‐wide perspective on reproductive strategies and floral traits Flowering plants have many modes of sexual reproduction, notably varying from selfing to outcrossing, and from bisexual flowers to individuals with separate sexes (dioecy). These reproductive modes ...

@yu1cheng.bsky.social, in collaboration with Filip Kolar and me, published an article looking at how the genetic architecture of unreduced gametes and environmental factors can affect autopolyploidy evolution.

Congrats Yu!

Just extended the deadline to March 21 for this position in the Plant Phylogenomics group at the University of Vienna. It is sort of a "post doc plus" position funded for up to six years.

Please reach out if you want to chat - I'd love to talk to you about it!

πŸ“’ Viewpoint in New Phyt. on polyploid establishment!
Key take-homes🧡
1. In contrast to earlier hypotheses that pollinators can help new polyploids establish, we suggest that pollinators mainly prevent polyploid establishment because outcrossing increases the strength of minority cytotype exclusion.
