Dissecting the complex molecular evolution and expression of polygalacturonase gene family in Brassica rapa ssp. chinensis.

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
Polygalacturonases (PGs) participate in pectin disassembly of cell wall and belong to one of the largest hydrolase families in plants. In this study, we identified 99 PG genes in Brassica rapa. Comprehensive analysis of phylogeny, gene structures, physico-chemical properties and coding sequence evolution demonstrated that plant PGs should be classified into seven divergent clades and each clade's members had specific sequence and structure characteristics, and/or were under specific selection pressures. Genomic distribution and retention rate analysis implied duplication events and biased retention contributed to PG family's expansion. Promoter divergence analysis using "shared motif method" revealed a significant correlation between regulatory and coding sequence evolution of PGs, and proved Clades A and E were of ancient origin. Quantitative real-time PCR analysis showed that expression patterns of PGs displayed group specificities in B. rapa. Particularly, nearly half of PG family members, especially those of Clades C, D and F, closely relates to reproductive development. Most duplicates showed similar expression profiles, suggesting dosage constraints accounted for preservation after duplication. Promoter-GUS assay further indicated PGs' extensive roles and possible redundancy during reproductive development. This work can provide a scientific classification of plant PGs, dissect the internal relationships between their evolution and expressions, and promote functional researches.
