Do you want an EMS-like drug that you can easily use in your lab or your garden shed to generate structural variation in your favorite plant? We show here that the topo2 inhibitor & common chemotherapy drug etoposide works really well to generate structural variation .
A simple method to efficiently generate structural variation in plants
Phenotypic variation is essential for the selection of new traits of interest. Structural variants, consisting of deletions, duplications, inversions, and translocations, have greater potential for ph...

Dr. Jane Goodall filmed an interview with Netflix in March 2025 that she understood would only be released after her death.

Just an outrageous amount of structural variation in pennycress. While not yet reproductively isolated, its likely these shredded pericentromeres contribute to some reproductive incompatibilities.

Whole-genome alignments revealed pennycress has nearly dichotomous genome compartmentalization: huge gene-poor pericentromeric regions (~300Mb; <1% genic) with frequent rearrangements and highly syntenic gene-rich chromosome arms (~150Mb; ~20% genic). What we call a "two-speed" genome structure. 3/
Figure 3 | Macrosynteny and genome structure across the Brassicaceae. Horizontal blue/black/orange bands represent the chromosomes of Arabidopsis thaliana, A. lyrata, MN106, and Brassica rapa (top to bottom). Chromosomes are ordered by their number from left to right. Colors represent genomic content binned hierarchically in sliding windows (400kb-overlapping 500kb) as follow: (1) within a gene annotation (including intron and UTR, orange), (2) within EDTA-annotated repeats categorized as Ty3, (3) Ty1 (copia), (4) within another repeat category, or (5) un-annotated. Grey bands are sequence-based syntenic blocks between each pair of genomes. Pennycress and B. rapa are phylogenetically proximate (both in Brassicodae supertribe), but have reduced synteny in part because of genome reshuffling in B. rapa following a whole-genome triplication event. The seven pennycress genome assemblies (horizontal bars) are binned into TRASH-defined centromeres (orange), pericentromeres (dark blue), chromosome arms (light blue) and telomeres (dark red). The colors along the chromosome segments scale physically with the size of the bin, except that centromeres and telomeres have a 1pt buffer to make it easier to see these typically small regions. Each genome is connected to its neighbor by grey polygons that represent sequence-based syntenic blocks. Plots, genomic bins, and syntenic blocks were built with DEEPSPACE (github.com/jtlovell/DEEPSPACE).

Out today in JAERE! We measure water pollution released at India's industrial clusters. Does it hurt agriculture? Surprisingly: Not by much

Come for how we published a paper of null results & with no regression tables

Stay for new ways to proxy for crop yields & map hydrological relationships

A reminder you/your lab can support FlyBase at Cambridge through the following link. Every bit helps. Please share if you yourself can't donate.

What’s your favorite food fact that is true but sounds totally made up?

I’ll start: about half of the mushrooms produced across the United States of America each year (more than 300 million pounds of mushrooms in recent years) are produced in *one county* in Pennsylvania.

Head of NASA Sean Duffy intends to destroy a satellite that collects key data on carbon dioxide and plant health, by causing it to burn up in the atmosphere. The U.S. Dept of Agriculture and private agriculture firms use the data to forecast crop yield, drought conditions and more.
Why a NASA satellite that scientists and farmers rely on may be destroyed on purpose
The Trump administration has asked NASA staffers to draw up plans to end at least two satellite missions that measure carbon dioxide in the atmosphere, according to current and former NASA employees.

Kinda curious why drosophila, but not arabidopsis,is allowed to have circular chromosomes

it's strange *how little* consciousness of the 1971 genocide in Bangladesh there is in the West, given how awful it was. a combination of racism and Cold War alliances with Pakistan, I suppose, but you'd think that there would have been *some* breakthrough book of the "Rape of Nanking" scale by now
