APETALA2 is involved in ABA signaling during seed germination.

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
APETALA2 (AP2) is well known for regulating the development of floral organs, ovules, seed coats, and the mass of seeds, but the role of AP2 in seed germination remains unclear. Here, we report that AP2 interacts with ABI5 in nuclear speckles and functions in controlling seed germination. Genetic study showed that the abi5 mutation could restore the ABA-sensitive phenotype of ap2 mutants, supporting that AP2 antagonizes ABI5 in ABA signaling and ABA-mediated inhibition of seed germination. In addition, we observed the interactions of AP2 with SnRK2.2, SnRK2.3, and SnRK2.6 in nuclear speckles, suggesting that AP2 plays a multifaceted role in the ABA signaling pathway. Our findings revealed that the interactions of AP2 with SnRK2s and ABI5 are critical for ABA signaling in control of seed germination.
