Identification of Solanum habrochaites loci that quantitatively influence tomato fruit ripening-associated ethylene emissions.
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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 phytohormone ethylene is essential for ripening of climacteric fruits such as tomato. While many of the genes responsible for ethylene synthesis and perception have been identified, the regulatory network controlling autocatalytic climacteric ethylene synthesis is not well understood. In order to better understand the regulation of ripening-associated ethylene, we have exploited the genetic variation within Solanum Sect. Lycopersicon. In particular, we have used a near-isogenic population of S. habrochaites introgression lines to identify chromosome segments affecting ethylene emissions during ripening. S. habrochaites fruits produce much larger quantities of ethylene during ripening than do cultivated S. lycopersicum tomatoes. A total of 17 segments were identified; 3 had emissions more than twice the level of the tomato parent, 11 had less than a twofold increase and 3 had significantly reduced emissions at one or more ripening stages. While several of these segments co-segregate with known ethylene-related genes, many do not correspond to known genes. Thus, they may identify novel modes of regulation. These results illustrate the utility of wild relatives and their introgression lines to understand regulation of fruit ripening-related processes.
