Proanthocyanidin-accumulating cells in Arabidopsis testa: regulation of differentiation and role in seed development.
Article in The Plant cell, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 187 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
Anthocyanidin reductase encoded by the BANYULS (BAN) gene is the core enzyme in proanthocyanidin (PA) biosynthesis. Here, we analyzed the developmental mechanisms that regulate the spatiotemporal expression of BAN in the developing Arabidopsis seed coat. PA-accumulating cells were localized histochemically in the inner integument (seed body and micropyle) and pigment strand (chalaza). BAN promoter activity was detected specifically in these cells. Gain-of-function experiments showed that an 86-bp promoter fragment functioned as an enhancer specific for PA-accumulating cells. Mutations in regulatory genes of PA biosynthesis abolished BAN promoter activity (transparent testa2 [tt2], tt8, and transparent testa glabra1 [ttg1]), modified its spatial pattern (tt1 and tt16), or had no influence (ttg2), thus revealing complex regulatory interactions at several developmental levels. Genetic ablation of PA-accumulating cells targeted by the BAN promoter fused to BARNASE led to the formation of normal plants that produced viable yellow seeds. Importantly, these seeds had no obvious defects in endosperm and embryo development.
