Chromosome fusions shaped karyotype evolution and evolutionary relationships in the model family Brassicaceae.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The ancestral crucifer karyotype and 22 conserved genomic blocks (CGBs) facilitate phylogenomic analyses in the Brassicaceae. Chromosomal rearrangements reshuffled CGBs of ancestral chromosomes during karyotype evolution. Here, we identify eight protochromosomes representing the common ancestral karyotype (ACBK) of the two Brassicoideae supertribes: Camelinodae (Lineage I) and Brassicodae (Lineage II). The characterization of multiple cascading fusion events allows us to infer evolutionary relationships based on these events. In the Camelinodae, the ACBK first evolved into the AKI genome, which remained conserved in the Cardamineae, whereas it was altered to tAKI by a reciprocal translocation that preceded the diversification of most Camelinodae tribes. The identified fusion breakpoints largely overlap with CGB boundaries, suggesting that CGBs are mainly disrupted by chromosome fusions. Our results demonstrate the stable inheritance of chromosome fusions and their importance for reconstructing evolutionary relationships. The chromosomal breakpoint approach provides a basis for ancestral state reconstruction based on chromosome-level genome assemblies.
