Characterization of maize B-chromosome-related transcripts isolated via cDNA-AFLP.

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 maize B-chromosome consists mainly of heterochromatin and is considered to be genetically inert. However, the B-chromosome contains euchromatin that carries control elements that direct its behaviors during cell division, such as nondisjunction during the second pollen mitosis. To determine the transcriptional activity of the B-chromosome, complementary DNA-amplified fragment length polymorphism analysis was applied to five inbred maize lines with and without B-chromosomes. Six putative B-chromosome-related transcripts were identified, four of which were cloned and characterized via Southern hybridization, fluorescence in situ hybridization, and sequence comparison to further confirm their B-chromosome origin. All the analyzed B-chromosome-related transcript sequences were repetitive and showed homology to A-chromosomes. Quantitative real-time reverse transcriptase-polymerase chain reaction revealed that the B-chromosome-specific transcribed sequences B3547-179 and B3849-212 were transcribed in a B-chromosome-dosage-dependent manner. Expression of B3849-189 and B3849-147 was not specific to the B-chromosome; however, the former showed a transcriptional pattern with B-chromosome dosage compensation, and the latter displayed down-regulation of transcription due to higher B-chromosome numbers. Using four B-10L translocations, B3849-212 was mapped to the B-chromosome region that contains the nondisjunction control elements of the B-chromosome. Taken together, our results suggested that the maize B-chromosome harbors few transcriptionally active sequences and might influence the transcription of A-chromosomes.
