The enigma of the B chromosome-specific behaviour.
Review in Frontiers in plant science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Supernumerary (B) chromosomes are widespread genomic elements that persist through non-Mendelian inheritance by exploiting host cellular mechanisms, yet the basis of their selective transmission and elimination remains poorly understood. This review integrates current knowledge on chromosome-specific behaviour, with particular emphasis on the centromere function, kinetochore assembly, epigenetic chromatin states, non-coding RNAs, and sequence composition. We examine how perturbations in these systems can skew chromosome segregation, or lead to chromosome elimination, and consider growing evidence that B chromosomes may themselves encode or modulate factors influencing these processes. Their repeat-rich architecture and enrichment in chromosome-specific satellite DNA are also discussed as contributors to their recognition by the cellular machinery. By unifying structural, epigenetic, and genetic perspectives, this review outlines a framework for understanding chromosome drive and elimination and highlights key directions for future research.
