A mutation in the tomato DDB1 gene affects cell and chloroplast compartment size and CDT1 transcript.
Article in Plant signaling & behavior, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Fruits harvested from tomato (Solanum lycopersicum) plants carrying mutations at the DAMAGED DNA BINDING PROTEIN 1 gene (SlDDB1; hp-1 and hp-1(w)) are characterized by significantly elevated levels of lycopene and several other phytonutrients. We hypothesize that the pleotropic effect on mutant Slddb1 are some general function of DDB1 protein on cell growth. The main objective of this research was to carry out functional analysis of the mutant SlDDB1 alleles both in-planta and ex-planta in comparison to their normal counterparts. Our major results indicate that: mutant Slddb1 seedlings exhibited delayed growth and smaller cell size, greater chloroplast density, smaller chloroplasts and higher concentration of chlorophyll.Cotyledons cells of Slddb1 mutant also displayed abnormal stomatal pattern, reduced content of CDT1 transcript and altered response to cytokinin. Some of these observations were previously described to be connected to defects in cell cycle control. Our results, coupled with former studies, also suggest that the CDD complex (composed of DDB1, DET1 and COP10) mediate the effect of light and cytokinin activity by possibly regulating the replication licensing factor CDT1 thus affecting both cell size and plastid multiplication.
