Arabinogalactan-proteins stimulate the organogenesis of guard cell protoplasts-derived callus in sugar beet.
Article in Plant cell reports, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Arabinogalactan proteins (AGPs) represent a class of proteoglycans implicated in the development and differentiation of cells and tissues both in planta and in vitro. Here we report that AGP-rich extracts isolated from media of embryogenic and non-embryogenic suspension cultures of sugar beet (Beta vulgaris L.) are able to enhance the organogenesis of guard protoplast-derived callus and to increase the number of shoots formed, in comparison to control cultures. Immunocytochemical detection of carbohydrate antigens in the extracts revealed the presence of epitopes that typify both AGP and pectin, the latter being frequently bound to AGPs or, in some cases, even contributing to the polysaccharide structure of proteoglycan molecules. The most abundant epitopes proved to be those recognized by the JIM13, LM2, and MAC207 antibodies, whereas some others could be found only in relatively small or trace amounts--these included epitopes recognized by JIM16, JIM5, and LM6. Surprisingly, the JIM4- and JIM8-binding epitopes that are expressed in the course of in vitro morphogenetic processes of many species could not be detected at all in sugar beet AGPs. This is the first report of the improvement of sugar beet protoplast-derived callus organogenesis by exogenous AGP-rich extracts, an achievement that will have great impact on the biotechnological applications of protoplast technology in this species.
