Cat is out of the bag! Later this summer I’ll make a big jump across the pond for 4 years to work on polyploid genome evolution and diploidization patterns across angiosperms as part of this awesome grant and team
📢Meet the Team!
Dr. Kevin Bird, starting this summer as a post-doctoral researcher at Royal Botanic Gardens, Kew. He will be looking for signs of asynchronous diploidization across angiosperms.

It took a long time to flower as the bud just kept getting bigger rather than opening.
Plenty of buds to come!

📢 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.
