In 2014, a wild idea was born: to follow female meiosis in Arabidopsis in real time. After many trials (including experiments with quirky mutants where female organs developed inside out, and a few other unconventional ideas), we switched gears to image the male side.

Monopolar orientation of kinetochores at meiosis is enforced by COHESINS and their regulators, CENP-C, and the deSUMOylase SPF2
The first division of meiosis is unique in its capacity to halve the ploidy of the future gametes. To this end, one key innovation compared to mitosis is the monopolar orientation of the pairs of sist...

Distribution of haploid chromosomes into separate nuclei in two pathogenic fungi
Nuclei define eukaryotes, enabling macromolecular compartmentalization and cellular regulation. Each nucleus is believed to contain one or more haploid sets of chromosomes (1N). However, we discovered...

Our latest work is out in @pnas.org! We have quantified and modeled the dynamics of early meiosis events, which can get really messy in polyploids (doubled number of chromosomes, double the trouble), but can also get fixed through adaptive evolution 🧵1/8.

A beautiful reminder that the classification of allo- and autopolyploid is indeed more complex than whether they have hybrid or non-hybrid origin.
Also, a beautiful reminder of how genome doubling can be a driver of agronomy-relevant innovations.
Great paper! www.nature.com/articles/s41...
