The post-fertilization archegonium gene network of seedless plants contributed to the origin of seeds - Nature Communications
The authors identify conserved gene networks across fern and angiosperm reproductive development, including between the sporophyte ovule and the fern gametophyte egg-chamber. Repurposing of this netwo...

So proud of this manuscript- lead by the fantastic @henryarenas.bsky.social with two undergraduates (Cage Cochran and Quinn Evans) each doing a Herculean effort during their honors theses, and Hongfei Chen helping out tremendously with lab work. www.biorxiv.org/content/10.6...
Maintenance of phenotypic divergence in two sympatric monkeyflowers with weak reproductive isolation
Sympatric species often exhibit permeable reproductive barriers, yet many of them coexist as phenotypically distinct entities. One way to account for this apparent paradox is that selection on loci th...

Our new preprint, led by Joanna Feehan, reveals that extreme physiological leaf cooling is key to survival at the upper thermal limit of eukaryotic life in the Death Valley desert plant Tidestromia oblongifolia. www.biorxiv.org/content/10.6...
Extreme cooling enables survival in extreme heat
Complex, multicellular extremophiles face intense challenges in coordinating their cells, tissues, and organs to function in harsh environments. Tidestromia oblongifolia is a desert plant that thrives...

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...
Balanced polymorphism in a floral transcription factor underlies the ancient rhythm of daily sex alternation in avocado | PNAS
In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

How do transcription factors bind DNA strongly, and in a switch like manner, while remaining sequence specific? Our new paper on a canonical plant TF suggests the answer is a previously underappreciated assembly state: transcription factor nanoclusters. www.science.org/doi/10.1126/...
Nanoclustering of a plant transcription factor enables strong yet specific DNA binding
Transcription factor nanoclusters balance the DNA binding trade-off between weakly binding oligomers and nonspecific condensates.

This is one of the most beautiful cross sections of cilia I've ever seen in our data, found by @csigulinsky.bsky.social. It is perfectly perpendicular to the plane of imaging which brings up an important point ~ connectomics. You gotta have enough resolution to see the important things. 2nm/px FTW!

New: The National Science Foundation is preparing to claw back some $500 million in funds from some of its core science programs in physics, math, computer science, and engineering in order to fund a project from the White House Office of Science and Technology Policy.
NSF plans cuts to core science programmes to fund White House initiative
A proposed clawback of already distributed research funds comes as the US agency’s budget is already squeezed and it struggling to clear a backlog of grant applications.
