Expression of polyamine biosynthesis genes during parthenocarpic fruit development in Citrus clementina.
Article in Planta, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Polyamines have been attributed a general role in fruit development in several plants like pea and tomato. To investigate the involvement of these compounds in parthenocarpic fruit development in Citrus clementina, we have isolated three genes encoding aminopropyl transferases in this species: CcSPDS, CcSPM1 and CcACL5. The unambiguous identity of the proteins encoded by these genes was confirmed by phylogenetic analysis and by heterologous expression in yeast mutants deficient in aminopropyl transferase activity. The expression of these genes in C. clementina is not restricted to ovaries and fruits, but it is also detectable all throughout the plant. More importantly, gibberellin-induced parthenocarpic fruit set caused a decrease in CcSPDS expression in ovaries, paralleled by a decrease in spermidine; while the expression of CcSPM1 and CcACL5 was basically unaffected, resulting in the maintenance of spermine concentration during early fruit development. In addition, the variation in putrescine content was paralleled by changes in the expression of one of the two putative CcODC paralogs.
