Functional characterization of Terminal Flower1 homolog in Cornus canadensis by genetic transformation.
Article in Plant cell reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
key messageTFL1homologCorcanTFL1suppresses the initiation of inflorescence development and regulates the inflorescence morphology inCornus canadensis. In flowering plants, there is a wide range of variation of inflorescence morphology. Despite the ecological and evolutionary importance, efforts devoted to the evolutionary study of the genetic basis of inflorescence morphology are far fewer compared to those on flower development. Our previous study on gene expression patterns suggested a CorTFL1-CorAP1 based model for the evolution of determinate umbels, heads, and mini dichasia from elongated inflorescences in Cornus. Here, we tested the function of CorcanTFL1 in regulating inflorescence development in Cornus canadensis through Agrobacterium-mediated transformation. We showed that transgenic plants overexpressing CorcanTFL1 displayed delayed or suppressed inflorescence initiation and development and extended periods of vegetative growth. Transgenic plants within which CorcanTFL1 had been down-regulated displayed earlier emergence of inflorescence and a reduction of bract and inflorescence sizes, conversions of leaves to bracts and axillary leaf buds to small inflorescences at the uppermost node bearing the inflorescence, or phyllotaxy changes of inflorescence branches and leaves from decussate opposite to spirally alternate. These observations support an important role of CorcanTFL1 in determining flowering time and the morphological destinies of leaves and buds at the node bearing the inflorescence. The evidence is in agreement with the predicted function of CorTFL1 from the gene expression model, supporting a key role of CorTFL1 in the evolutionary divergence of inflorescence forms in Cornus.
