Ectopic expression of OsYAB1 causes extra stamens and carpels in rice.

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
Members in the YABBY gene family of proteins are plant-specific transcription factors that play critical roles in determining organ polarity. We have isolated a cDNA clone from rice that encodes a YABBY protein. This protein, OsYAB1, is similar to Arabidopsis YAB2 (50.3%) and YAB5 (47.6%). It carries a zinc-finger motif and a YABBY domain, as do those in Arabidopsis . A fusion protein between OsYAB1 and GFP is located in the nucleus. RNA gel-blot analysis showed that the OsYAB1 gene is preferentially expressed in flowers. In-situ hybridization experiments also indicated that the transcript accumulated in the stamen and carpel primordia. Unlike the Arabidopsis YABBY genes, however, the OsYAB1 gene does not show polar expression pattern in the tissues of floral organs. Our transgenic plants that ectopically expressed OsYAB1 were normal during the vegetative growth period, but then showed abnormalities in their floral structures. Spikelets contained supernumerary stamens and carpels compared with those of the wild types. These results suggest that OsYAB1 plays a major role in meristem development and maintenance of stamens and carpels, rather than in determining polarity.
