1 · What the graph read from it

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.

2 · The registry

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 potato genotype ND4382-19 has Solanum chacoense Bitt. in its genetic background. Foliar alkaloid analysis of it and its progeny ND5873 (ND4382-19 × Chipeta) by gas chromatography-mass spectrometry (GC-MS) showed that, in addition to the expected alkaloids (solanidine, leptinidine, and acetyl-leptinidine), there was an aglycone of another rare alkaloid. Its molecular mass and some of the m/z fragment ions were similar to leptinidine, but the major fragment ion was the m/z 150 peak of solanidine. This fragmentation pattern suggested that this alkaloid is a solanidine-based compound with mass equal to leptinidine. Leptinidine differs from solanidine by an extra -OH group, but the GC-MS fragmentation pattern of the rare compound indicated hydroxylation at a different position than the C-23 of leptinidine. The exact chemical structure is still unknown, and further analysis, such as NMR will be necessary to determine the structure. Segregation analysis of ND5873 (ND4382-19 × Chipeta) showed that presence of this rare compound segregated in a 1:1 ratio, indicating that a single gene controlled its synthesis and/or accumulation in foliar tissue. Analysis with AFLP and microsatellite markers indicated that the locus-controlling presence of this alkaloid resided on potato chromosome I, with the nearest flanking AFLP markers 0.6 and 9.4 cM apart. This rare alkaloid was present in the foliage and not detected in potato tubers. Its presence in leaves did not affect resistance/susceptibility to Colorado potato beetle.
