Promoter analysis and expression of a phospholipase D gene from castor bean.
Article in Plant physiology, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The expression of a castor bean (Ricinus communis L.) phospholipase D (PLD; EC 3.1.4.4) gene has been studied by examining its promoter activity in transgenic tobacco (Nicotiana tabacum) carrying a PLD promoter-glucuronidase transgene and by monitoring the levels of PLD mRNA in castor bean. Sequence and the 5' truncation analyses revealed that the 5' flanking region from nucleotide -1200 to -730 is required for the regulation and basal function of the PLD promoter. The PLD promoter in vegetative tissues is highly active in the rapidly growing regions such as the shoot apex and the secondary meristem producing axillary buds and vascular tissues of young leaves and stems. The PLD promoter activity in floral tissues was high in stigma, ovary, and pollen grains, but low in petals, sepals, the epidermis of anthers, styles, and filaments. The PLD promoter activity was enhanced by abscisic acid. Northern-blot analysis of PLD in castor bean showed that the PLD mRNA levels were high in young and metabolically more active tissues such as expanding leaves, hypocotyl hooks, developing seeds, and young seedlings, and they decreased in mature tissues such as fully expanded leaves and developed seeds. These patterns of expression suggest a role of PLD in rapid cell growth, proliferation, and reproduction.
