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 Cornell Chronicle highlighted our recent Current Biology paper, showing how cell growth and tissue mechanics work together to shape developing sepals—and how these principles could help engineer living materials. news.cornell.edu/stories/2026...

Wrinkled or smooth? Cell growth mechanics determine shape of plant organs | Cornell Chronicle

This discovery could help engineer living materials into different forms, such as the custom of growing bridges from roots in India, and breeding kale so it’s smooth instead of crinkly.

How do plant organs stay smooth—or become wrinkled? 🌱 Our paper in @currentbiology.bsky.social shows how coordinated growth direction and mechanical properties across cell layers determine whether Arabidopsis sepals remain smooth or buckle. cell.com/current-biol...

How does a growing leaf stay flat? 🍃 Our new paper in @plosbiology.org shows that maintaining leaf flatness requires growth-rate coordination across the width of the leaf blade—not just between the top and bottom surfaces. journals.plos.org/plosbiology/...

The growth of #plant leaves is highly dynamic and should be coordinated, but how is #leaf flatness preserved? @roederlab.bsky.social &co show that global coordination of growth across the leaf blade is required to maintain flatness in #Arabidopsis @plosbiology.org 🧪 buff.ly/QUMxOcF

While WT leaves progressively flatten, jaw-D leaves curve at the base. Gaussian curvature displayed as heatmaps on wildtype (left) and jaw-D mutant (right) leaf meshes. Gaussian curvature represents both the magnitude and direction of curvature such that values further from zero represent greater curvature. Orange arrows indicate high positive curvature that develops at the base of jaw-D leaves. Black scale bars = 200 µm.

Vascular plants and mosses both produce Fibonacci-like spiral phyllotaxis, but diverged 450MYA. One uses auxin transport across a multicellular meristem to get the shape, the other does so via a single cell dividing such that new walls avoid oldest neighbors. Convergent evolution or deep homology?
