An alternative mechanism for cleistogamy in barley.
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Cleistogamy in barley is genetically determined by the presence of the recessive allele cly1, but the dominant allele at the linked locus Cly2 is epistatic over cly1. Although the molecular basis for cly1 action is well understood, that of Cly2 is not. Here we show that anther non-extrusion can occur not just when the lodicules fail to expand adequately (a trait which is fully determined by the allelic state at the cly1 locus), but by the premature timing of anthesis before the spike has emerged from the boot. The transcription of HvAP2 at cly1 is unaffected by the timing of anthesis. Where this occurs prematurely, by the time that the spike has emerged from the boot, the lodicules have already become shrunken and have lost the capacity to push the lemma and palea apart. Premature anthesis appears to be governed by a dominant gene, probably Cly2. Of the three phases of development of a non-cleistogamous barley floret (spike emergence from the boot, floret gaping induced by lodicule expansion and anther extrusion), genetic variation is available regarding at least the former two.
