Two CENH3 paralogs in the green alga Chlamydomonas reinhardtii have a redundantly essential function and associate with ZeppL‐LINE1 elements
Histone H3 variant CENP-A/CENH3 is a conserved centromere protein in eukaryotes but has not been well characterized in green algae. Our data establish the function of CENH3 at Chlamydomonas centromer....

Amazing study from Jill Anderson, Megan Demarche and colleagues, integrating species distribution models, reciprocal transplants, snow manipulation and more to test whether a montane plant can adapt to climate change. The sad answer: not without human intervention.

Five weeks into what has been a constant onslaught on science, working on a paper seems like such a privilege, which many of our recently fired colleagues no longer have.

And a rebellious act.

But mostly it's self-care.

Yibing Zeng used synthetic centromeres to break chromosome 4 into two separate chromosomes (4a and 4b), raising the diploid chromosome number of maize from 20 to 22. The resulting plants grew and reproduced normally. We call this process engineered chromosome fission www.biorxiv.org/content/10.1...
Increased maize chromosome number by engineered chromosome fission
Activation of synthetic centromeres on chromosome 4 in maize leads to its breakage and formation of trisomic fragments called neochromosomes. A limitation of neochromosomes is their low and unpredicta...

Meghan Brady showed that one of the kinesins (Trkin) on the Ab10 meiotic drive haplotype does not serve a useful function in drive or fitness. Anjali Gupta and Rob Unckless used modeling to show that Ab10 Trkin should not persist. Something strange is going on www.biorxiv.org/content/10.1...
Antagonistic kinesin-14s within a single chromosomal drive haplotype
In maize, there are two meiotic drive systems that operate on large tandem repeat arrays called knobs that are found on chromosome arms. One meiotic drive haplotype, Abnormal chromosome 10 (Ab10), enc...

Rebecca Piri showed that the maize centromere repeat CentC likely does not have a role in centromere function, whereas knob repeat arrays (involved in meiotic drive) have conserved higher order repeats (HORs) and huge repeat units of ~1 Mb that are shared among knobs www.biorxiv.org/content/10.1...
Higher order repeat structures reflect diverging evolutionary paths in maize centromeres and knobs
Background Highly repetitive tandem repeat arrays, known as satellite DNAs, are frequently found in low recombination regions such as centromeres. Satellite arrays often contain complex internal struc...

I am pleased to introduce three papers from our lab this week, describing the structure of repeat arrays, the fitness effects of a key meiotic drive gene, and karyotype engineering.
