Roles of UV-damaged DNA binding protein 1 (DDB1) in epigenetically modifying multiple traits of agronomic importance in tomato.
Article in Plant signaling & behavior, 2012. 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
Epigenetic regulation participates broadly in many fundamentally cellular and physiological processes. In this study, we found that DDB1, a protein originally identified as a factor involved in DNA repairing, plays important roles in regulating organ size, growth habit and photosynthesis in tomato via an epigenetic manner. We generated transgenic tomato plants overexpressing an alternatively spliced DDB1 transcript (DDB1(F) , prevalently present in tomato tissues) and found the primary transformants displayed small-fruited "cherry tomato" in companion with strikingly enhanced shoot branching and biomass, dark-green leaves with elevated chlorophyll accumulation, and increased soluble solids in fruits. Significantly, these phenotypic alterations did not segregate with the DDB1(F) transgene in subsequent generations, suggesting that the effect of DDB1(F) on multiple agronomic traits is implemented via an epigenetic manner and is inheritable over generations. We speculate that DDB1, as a core subunit in the recently identified CUL4-based E3 ligase complex, mediates the 26S proteasome-dependent degradation of a large number of proteins, some of which might be required for perpetuating epigenetic marks on chromatins.
