Coppage et al. identify four ancient polyploidy events with unusually high duplicate gene retention. Elevated gene conversion and delayed diploidization suggest a distinct class of paleopolyploid genomes.

While we were examining cell cycle dynamics in the male accessory gland, we noticed dynamic cell cycles also taking place in the neighboring maturing Ejaculatory Duct. This work is the result of our investigation into this less well-characterized tissue, essential for reproduction. Please share with those interested in #polyploidy, and #cell cycle responses to #hormonal signaling.

Interesting paper. They see different DNA repair strategies in postmitotic neurons and induction of cell cycle genes in neurons with Cas9 induced DSBs. This is consistent with our work that DNA damage may influence cell cycle gene expression and #polyploidy in the 🪰brain. (Nandakumar et al 2020). Still so much to be worked out.

A new preprint from the lab on the distribution of ancient whole-genome duplications across the angiosperm phylogeny. Great work led by PhD student Michael McKibben! We used a variety of methods and different species trees to infer and place WGDs across the phylogeny. Overall, similar results to our past work, but species tree had a large impact on WGD inferences. Check it out here:

Polyploidy used to be abnormal. Something alarming that showed up in tumors. But somehow also natural (think livers) and widespread in the natural world (think plants and speciation). NOW we find it has a natural function in wound-healing. Cool. #science #complex #polyploidy #stressors
