Organelle DNA contents and starch accumulation in potato tubers.

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
key messageStarch contents were found to be positively correlated with organelle/nuclear DNA ratios, suggesting that these ratios are involved in starch accumulation and may serve as a target trait in genetic engineering and a biomarker in breeding for improving the dry matter and starch production in potato. Starch is the main dry matter component of various staple food crops, including potato. Starch synthesis and accumulation is in plastids, uses sugar, consumes cellular energy, and requires active expression of starch synthesis genes. We hypothesized that the plastid/nuclear DNA ratios and mitochondrial/nuclear DNA ratios are involved in this accumulation. We analyzed the dry mater, starch, plastid DNA, mitochondrial DNA, and nuclear DNA in tuber stem ends and tuber bud ends in two potato cultivars and verified the results using whole tubers in nine potato cultivars. Dry matter contents (DMC) and organelle/nuclear DNA ratios increased rapidly during tuber bulking. DMC and starch contents were greater at the tuber stem ends than at the tuber bud ends. Both the comparisons between tuber ends and among whole tubers indicated that DMC and starch contents were positively correlated with both plastid/nuclear DNA ratios and mitochondrial/nuclear DNA ratios. The results suggest that pt/nuc and mt/nuc DNA ratios are important and may serve as a biomarker in selection, genetic engineering, and cytoplasm manipulation, for dry matter and starch accumulation in potato.
