An artificial miRNA as a new tool to silence and explore gene functions in apple.

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
Artificial miRNA (amiRNA) is a powerful technology to silence genes of interest. It has a high efficiency and specificity that can be used to explore gene function through targeted gene regulation or to create new traits. To develop this gene regulation tool in apple, we designed two amiRNA constructs based on an apple endogenous miRNA backbone previously characterized (Md-miR156h), and we checked their efficiency on an easily scorable marker gene: the phytoene desaturase gene (MdPDS in apple). Two pairs of miRNA:miRNA* regions were designed (named h and w). The monocistronic Md-miR156h with these MdPDS targets was placed under the control of the CaMV 35S promoter to generate the two plasmids: pAmiRNA156h-PDSh and pAmiRNA156h-PDSw. Two Agrobacterium-mediated transformation experiments were performed on the cultivar 'Gala'. A total of 11 independent transgenic clones were obtained in the first experiment and 5 in the second. Most transgenic lines had a typical albino and dwarf phenotype. However, six clones had a wild type green phenotype. Molecular analyses indicated clear relationships between the degree of albino phenotype, the level of MdPDS gene expression and the amount of mature amiRNAs. This study demonstrated for the first time in apple the functionality of an artificial miRNA based on an endogenous miRNA backbone. It provides important opportunities for apple genetic functional studies as well as apple genetic improvement projects.
