Congrats all!! Been fun watching this work come together from afar!
Mutant alleles that affect pollen fitness can generate spatial inheritance patterns on maize ears β see the article by Ruggiero et al. Top Left: Maize pollen grains germinated on a silk, with pollen tubes (stained with aniline blue) growing into the silk interior. Image Credit: Caity Smyth. Bottom Left: Unpollinated maize ear with silks arranged to show that silks derived from ovules at the base of the ear are longer than silks from ovules at the ear apex. Image Credit: Elyse Vischulis. Right: Ear projection from a mature ear pollinated with the pollen from a plant heterozygous for the bag1*::Ds-GFP insertion, oriented apex-to-base top-to-bottom (as in bottom left ear/silk image). The GFP-marked bag1* allele is associated with a spatial pattern of fewer fluorescent kernels towards the base of the ear β i.e., kernels generated following pollen tube growth down the longest silks.
Very pleased to see this work from the group out in The Plant Journal - led by PhD student Diana Ruggiero from the Leiboff group, a truly collaborative project, addressing the question: how often does pollen genotype influence spatial patterns of inheritance? onlinelibrary.wiley.com/doi/10.1111/...
How to choose a sweet cherry tree. All of these are self fertile, hardy, and decent on disease/cracking resistance.
Lapin - Highest yield and more 'rich' flavor
Black Gold - Easy to grow, less yield than lapin, clean flavor
Sweetheart - Late season. Rich flavor
Stella - Early Season. Clean Flavor

I am also shocked by the lack of coverage of this fire. Itβs so far only affecting the Union Street buildings, but one of those has partially collapsed, from what I can tell backwards into the station. And itβs not yet contained. This is major and more than halfway down BBCβs homepage.
πΏ Postdoc opportunity in plant evolutionary ecology/genetics!
My lab in the Dept. of Ecology & Evolutionary Biology at the University of Michigan is recruiting a postdoctoral researcher to start Fall 2026.
We study plant adaptation, using weeds as model systems.

A detailed digital composite image based on the 1947 historical photograph of geneticist Barbara McClintock. McClintock, with her characteristic short hair and round glasses, is seated at a microscope, using tweezers in a Petri dish. While based on the original photo distributed for her AAUW award, this image presents a significantly expanded and fictionalized laboratory environment. The simple wooden workbench is now densely populated with a vast, colorized collection of complex glassware, numerous amber-colored reagent bottles, intricate distillation columns, and botanical specimens relevant to maize cytogenetics, creating a rich, illustrative narrative of her "jumping gene" research context that was not present in the original photo. The expanded background shows complex vintage laboratory cabinetry. This image explicitly states it is a composite: a digital recreation where Seriously Scientific has taken the historical figure and placed them into an augmented, complex fictionalized environment. Based on original source from Smithsonian Institution Archives. Digital composite by Seriously Scientific.
Remembering Barbara McClintock on International Women's Day!
She discovered that genes aren't static, they can actually "jump" around on a chromosome.
Her discovery of transposons ("jumping genes") fundamentally changed how we understand evolution and the complexity of DNA! π§¬π½

Thanks to @dvonwangenheim.bsky.social and new i3 spinning disk @the.3i.social
Excited to share this preprint that describes my latest work on using GPUs to accelerate processing of RNA-seq data.
The title says it all: "RNA-seq analysis in seconds using GPUs" now on biorxiv www.biorxiv.org/content/10.6... and github github.com/pachterlab/k...
Figure 1 shows they key result
HCR is gonna be such a fantastic technique for the field of developmental biology in the years going forward
Please check out our new preprint! Using single cell analysis paired with HCR to visualize transcript localization we have identified cell and tissue-specific expression of various genes encoding tubulins, kifs, and dyneins during neural crest development!
Ummm... Excuse me, can I help you find something?
If you're doomscrolling, guess what? So far there are 51 kΔkΔpΕ chicks hatched and thriving this season, the same number of birds as we had in TOTAL in the 90s! Only one chick has died and there are still fertile eggs waiting to hatch!
Our work on #hornwort #pyrenoids is finally out in @science.org! π We uncovered how hornworts pack their Rubisco into pyrenoids and successfully recreated them in Arabidopsis.

An odd little plantβthe hornwortβjust gave scientists a blueprint for how to make crops more efficient.

Researchers in the US might be having feelings about writing grants atm-I know I am!
We still need to write them. In this Evolution Exchange, I again chat with Sam Scheiner, who summarizes how to write a competitive proposal.
His advice is gold, and helpful regardless of funder. Pls RT!

I am very excited to share my simultaneous triple staining method for monocot roots. This method is not only faster but also utilizes a smaller volume of stain than traditional methods and minimizes mechanical tissue damage.

So, any other news yesterday?
Anything important?
In principle the main extent of explorable morphospace should saturate in reasonably short order if there isnβt a strong penalty for such random walks, at which point more incremental tweaking would take over, so is this approaching a textbook case of neutral evolution?
