BAC- and oligo-FISH mapping reveals chromosome evolution among Vigna angularis, V. unguiculata, and Phaseolus vulgaris.
Article in Chromosoma, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
Cytogenomic resources have accelerated synteny and chromosome evolution studies in plant species, including legumes. Here, we established the first cytogenetic map of V. angularis (Va, subgenus Ceratotropis) and compared this new map with those of V. unguiculata (Vu, subgenus Vigna) and P. vulgaris (Pv) by BAC-FISH and oligopainting approaches. We mapped 19 Vu BACs and 35S rDNA probes to the 11 chromosome pairs of Va, Vu, and Pv. Vigna angularis shared a high degree of macrosynteny with Vu and Pv, with five conserved syntenic chromosomes. Additionally, we developed two oligo probes (Pv2 and Pv3) used to paint Vigna orthologous chromosomes. We confirmed two reciprocal translocations (chromosomes 2 and 3 and 1 and 8) that have occurred after the Vigna and Phaseolus divergence (~9.7 Mya). Besides, two inversions (2 and 4) and one translocation (1 and 5) have occurred after Vigna and Ceratotropis subgenera separation (~3.6 Mya). We also observed distinct oligopainting patterns for chromosomes 2 and 3 of Vigna species. Both Vigna species shared similar major rearrangements compared to Pv: one translocation (2 and 3) and one inversion (chromosome 3). The sequence synteny identified additional inversions and/or intrachromosomal translocations involving pericentromeric regions of both orthologous chromosomes. We propose chromosomes 2 and 3 as hotspots for chromosomal rearrangements and de novo centromere formation within and between Vigna and Phaseolus. Our BAC- and oligo-FISH mapping contributed to physically trace the chromosome evolution of Vigna and Phaseolus and its application in further studies of both genera.
