Seed shattering in a wild sorghum is conferred by a locus unrelated to domestication.

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
Suppression of seed shattering was a key step during crop domestication that we have previously suggested to be convergent among independent cereal lineages. Positional, association, expression, and mutant complementation data all implicate a WRKY transcription factor, SpWRKY, in conferring shattering to a wild sorghum relative, Sorghum propinquum. We hypothesize that SpWRKY functions in a manner analogous to Medicago and Arabidopsis homologs that regulate cell wall biosynthesis genes, with low expression toward the end of floral development derepressing downstream cell wall biosynthesis genes to allow deposition of lignin that initiates the abscission zone in the seed-pedicel junction. The recent discovery of a YABBY locus that confers shattering within Sorghum bicolor and other cereals validated our prior hypothesis that some parallel domestication may have been convergent. Ironically, however, the shattering allele of SpWRKY appears to be recently evolved in S. propinquum and illustrates a case in which the genetic control of a trait in a wild relative fails to extrapolate even to closely related crops. Remarkably, the SpWRKY and YABBY loci lie only 300 kb apart and may have appeared to be a single genetic locus in some sorghum populations.
