Negative regulation of KNOX expression in tomato leaves.
Article in Planta, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
Leaves of seed plants can be described as simple, where the leaf blade is entire, or dissected, where the blade is divided into distinct leaflets. Both simple and dissected leaves are initiated at the flanks of a pluripotent structure termed the shoot apical meristem (SAM). In simple-leafed species, expression of class I KNOTTED1-like homeobox (KNOX) proteins is confined to the meristem while in many dissected leaf plants, including tomato, KNOX expression persists in leaf primordia. Elevation of KNOX expression in tomato leaves can result in increased leaflet number, indicating that tight regulation of KNOX expression may help define the degree of leaf dissection in this species. To test this hypothesis and understand the mechanisms controlling leaf dissection in tomato, we studied the clausa (clau) and tripinnate (tp) mutants both of which condition increased leaflet number phenotypes. We show that TRIPINNATE and CLAUSA act together, to restrict the expression level and domain of the KNOX genes Tkn1 and LeT6/Tkn2 during tomato leaf development. Because loss of CLAU or TP activity results in increased KNOX expression predominantly on the adaxial (upper) leaf domain, our observations indicate that CLAU and TP may participate in a domain-specific KNOX repressive system that delimits the ability of the tomato leaf to generate leaflets.
