Regulation of phenylalanine ammonia-lyase (PAL) gene family in wood forming tissue of Populus trichocarpa.

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
Phenylalanine ammonia-lyase (PAL) catalyzes the initial step of phenylpropanoid biosynthesis in plants. Five PAL genes (PtrPAL1 to 5) have been identified in Populus trichocarpa. These genes are classified into two subgroups according to their transcript sequence similarity and tissue specificity. However, the regulation of these genes and their protein functions are not well understood. In this study, enzymatic properties of each PtrPALs were characterized based on their recombinant proteins expressed in E.coli. Subcellular localizations of each PtrPALs in stem wood forming tissue were investigated and individual PtrPAL protein abundances in cytosol and membrane protein fractions were measured using protein cleavage-isotope dilution mass spectrometry (PC-IDMS). Protein/mRNA ratios of PtrPALs were further verified using RNA-Seq and gel-enhanced liquid chromatography mass spectrometry (GeLC-MS). All PtrPALs have similar catalytic properties for the deamination of L-phenylalanine, their major substrate. All PtrPALs have similar subcellular locations in stem wood forming tissue, with major amount in the cytosol (93-96 %) and less in the membrane (4-7 %). However, the protein/mRNA ratios of subgroup A (PtrPAL2, 4 and 5) are about five times that of subgroup B (PtrPAL1 and 3) in stem wood forming tissue, while all PtrPALs have similar transcript abundances. These results indicate a greater functional significance of subgroup A PtrPALs for stem wood formation, and highlight the role of gene post-transcriptional regulation.
