The E3 ligase TaE3V-B1 ubiquitinates proteins encoded by the vernalization gene TaVRN1 and regulates developmental processes in wheat.

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
In wheat (Triticum aestivum), early maturity is desired to avoid the hot and dry summer season, especially in view of climate change. Here, we report that TaE3V1, a C3H2C3 RING-type E3 ligase that interacts with TaVRN1, is associated with early development. Aside from its RING domain, TaE3V1 does not harbor any domains that are conserved in other RING-type or other E3 ligase proteins. TaE3V-B1b, encoded by the functional TaE3V1 allele, interacts with and ubiquitinates TaVRN1. In contrast, TaE3V-B1a, encoded by a natural nonfunctional TaE3V1 allele, neither interacts with TaVRN1 nor has E3 ligase activity. TaE3V-B1b activity decreases with plant age under warmer temperatures, but not under the low temperatures required for vernalization. We employed a gene editing method to simultaneously inactivate the 3 homoeologous TaE3V1 genes to validate their functions. Overall, our results suggest that the naturally mutated and edited TaE3V1 alleles can accelerate wheat development and aid adaptation to warming climates.
