Reactivation of an inactive centromere reveals epigenetic and structural components for centromere specification in maize.
Article in The Plant cell, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 85 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
Stable maize (Zea mays) chromosomes were recovered from an unstable dicentric containing large and small versions of the B chromosome centromere. In the stable chromosome, the smaller centromere had become inactivated. This inactive centromere can be inherited from one generation to the next attached to the active version and loses all known cytological and molecular properties of active centromeres. When separated from the active centromere by intrachromosomal recombination, the inactive centromere can be reactivated. The reactivated centromere regains the molecular attributes of activity in anaphase I of meiosis. When two copies of the dicentric chromosome with one active and one inactive centromere are present, homologous chromosome pairing reduces the frequency of intrachromosomal recombination and thus decreases, but does not eliminate, the reactivation of inactive centromeres. These findings indicate an epigenetic component to centromere specification in that centromere inactivation can be directed by joining two centromeres in opposition. These findings also indicate a structural aspect to centromere specification revealed by the gain of activity at the site of the previously inactive sequences.
