Biochemical characterization and expression analysis of lignification in two pear (Pyrus ussuriensis Maxim.) varieties with contrasting stone cell content.

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
As lignified stone cells reduce fruit quality, we investigated lignin deposition, phenolic metabolites, and expression of lignin biosynthetic genes during fruit development to elucidate the molecular mechanism of stone cell lignification using histological, biochemical, and transcriptional data from two Ussurian pear varieties (Jianba and Nanguo) with contrasting stone cell content. Lignin content and distribution coincided with stone cell accumulation. As per LC-MS analysis, Jianba exhibited higher levels of lignin monomers and hydroxycinnamates than Nanguo, consistently with lignin amount in each case. However, flavonoid content was much higher in Nanguo. Transcriptional data showed that most monolignol biosynthesis-related genes were particularly upregulated in Jianba during lignin accumulation; especially CCR and LAC, two monolignol biosynthesis-specific genes, were substantially upregulated in Jianba fruits at critical stages. Therefore, differences in stone cell content between "Jianba" and "Nanguo" may result from differential expression of lignin synthase genes located downstream of the lignin biosynthesis pathway. Taken together, our data may provide a deeper understanding of the molecular mechanism for stone cell lignification in pear fruit.
