Expression profiling of starch metabolism-related plastidic translocator genes in rice.

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
The genes encoding the major putative rice plastidic translocators involved in the carbon flow related to starch metabolism were identified by exhaustive database searches. The genes identified were two for the triose phosphate/phosphate translocator (TPT), five for the glucose 6-phosphate/phosphate translocator (GPT) including putatively non-functional ones, four for the phosphoenolpyruvate/phosphate translocator (PPT), three for the putative ADP-glucose translocator (or Brittle-1 protein, BT1), two for the plastidic nucleotide transport protein (NTT), and one each for the plastidic glucose translocator (pGlcT) and the maltose translocator (MT). The expression patterns of the genes in various photosynthetic and non-photosynthetic organs were examined by quantitative real-time PCR. OsBT1-1 was specifically expressed in the seed and its transcript level tremendously increased at the onset of vigorous starch production in the endosperm, suggesting that the ADP-glucose synthesized in the cytosol is a major precursor for starch biosynthesis in the endosperm amyloplast. In contrast, all of the genes for OsTPT, OsPPT, and OsNTT were mainly expressed in source tissues, suggesting that their proteins play essential roles in the regulation of carbohydrate metabolism in chloroplasts. Substantial expression of the four OsGPT genes and the OspGlcT gene in both source and sink organs suggests that the transport of glucose phosphate and glucose is physiologically important in both photosynthetic and non-photosynthetic tissues. The present study shows that comprehensive analysis of expression patterns of the plastidic translocator genes is a valuable tool for the elucidation of the functions of the translocators in the regulation of starch metabolism in rice.
