Saw this cool work in a recent seminar by @harmitmalik.bsky.social "Mst77F protects the D. melanogaster X chromosome from a killer-target meiotic drive system in a dosage- and sequence-dependent manner."

Very excited to share the first preprint from my PhD with the community! This is also the first paper from the Plant Immunogenomics group with @galofir.bsky.social, so stay tuned for more!

A new plant-bacteria immunological connection in the first preprint of our group at @mpi-bio-fml.bsky.social @plantevolution.bsky.social!

Now, the next chapter!

Our lab at the Institute of Molecular Biology, Academia Sinica in Taiwan, is fully up and running. We are actively recruiting passionate researchers at all levels to tackle bold ideas in cell biology, chromosome architecture, and evolution:

🧵 on why you should not be coy about pitching new ideas to prospective postdoc advisors (even if you have to tell them you have a better idea than they do)

NEW: In March the White House released an FY27 budget request that zeroed out the National Science Foundation's directorate of Social, Behavioral and Economic Sciences (SBE). For months it was unclear what would happen. Now, with FY26 over, the damage to SBE is coming to light. My reporting:

This is it. This is what everyone is enabling by humoring genAI: you spend months writing something that took you years to get at, for an opaque algorithm that a few control to spit a number and cut you off right there and then. This is what we're up against 🧪

Don't new traits evolve by rewiring of GRNs (which can of course consist of conserved and non-conserved elements)?

@plantevolution.bsky.socialSep 29, 2026, 6:15 AM

Random answer: Define “controlled”. Many seem to confuse the fact that manipulation of a gene may disturb a process with “control” or “regulation” of said process. I’d therefore extend your thought: “Just because a gene AFFECTS a conserved process …”

@spicybotrytis.bsky.socialSep 29, 2026, 12:50 AMReposted by @plantevolution.bsky.social

In today’s random thoughts. Just because a gene controls a conserved process does not suggest or even support that the gene is conserved. Lots of family specific genes input into or control highly conserved processes.

For the last 34 years I have been on the faculty of the UNC-Chapel Hill Department of Biology and have never regretted that decision. This year we are hiring TWO new Assistant Professors in the broad area of Molecular, Cell, Developmental Biology 1/n

Please pass along: I’m recruiting PhD students to join our Macroecology Lab. We study physical ecology, macroecology, and biodiversity — spanning scaling, trait-based ecology, theory, comparative biology & ecoinformatics. Several avenues for funding. Please reach out if interested 🧪🌐🌾

Are you looking for a postdoc exploring the cell biology of development, defining how cells change shape and move? Do you want to develop a research program & teaching skills preparing you for a position at a college or small University? Our new NIH grant will support those goals 1/n Please share

Wir brauchen ein Wort für die seltsam verquere Freude, in einem Text Holprigkeiten oder Fehler zu finden, weil es uns zeigt, dass er nicht von einer verdammten AI geschrieben wurde.

Cool new work from @thanvisrikant.bsky.social & @kbomblies.bsky.social: Chromosomes in #Arabidopsis thaliana neo-polyploids break preferentially at fragile sites that correspond to ancient genome rearrangements
#plantscience
www.biorxiv.org/content/10.6...

Detection and analyses of aneuploidies in neo-tetraploid A. thaliana. (A) Schematic
representation of how neo-tetraploid F1 were generated through reciprocal crossing of Col-0 and
Ler neo-tetraploid inbreds. See Figure S1A for more details. (B-D) Examples of aneuploidy
detection using sequencing coverage data from three F1 individuals, “Cross_3_Plant_32”,
“Cross_3_Plant_25” and “Cross_38_Plant_01”, respectively (Figure S2, S3). The upper panels
show aneuploidy detection using a read-coverage approach and the lower panels show a
variant-calling based approach. The Ler chromosomes are indicated as L1-L5 (orange) and Col-
0 chromosomes are indicated as C1-C5 (blue). In both panels, every data point represents a
mean value (normalised read coverage / allele frequency) in a 100kb window of the genome.
For the upper panels, sequencing data are mapped to an in-silico hybrid genome that combines
TAIR10.1 (Col-0) and Ler. For the lower panels, the sequencing data are mapped to a Ler
reference genome. (B) Data from a euploid individual with normalised coverage consistent with
two copies of each maternally and paternally inherited chromosome (upper panel), and allele
frequencies clustering around 0.5 when mapped to a Ler reference genome (lower panel). (C)
Data from an individual affected by a full-length aneuploidy – a loss of one Chromosome 2 copy
from Col-0, resulting in a drop in coverage (upper panel) and sharp changes in allele frequency
(lower chromosome) for Chr2. (D) Data from an individual affected by a segmental loss of part
of Chromosome 4 from the Ler parent.

The curious case of the placental genome

In this Review, Zoé Ducarne, @agathechaigne.bsky.social and @myanhtruong.bsky.social highlight the placenta, the only mammalian organ that harbors a cancer-like genome while remaining functional and healthy.

Diagrams of a blastocyst and full-term placenta in human. More details in the paper.
