Defense-Related Transcript Accumulation in Phaseolus vulgaris L. Colonized by the Arbuscular Mycorrhizal Fungus Glomus intraradices Schenck Smith.
Article in Plant physiology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
Accumulation of mRNAs for the defense-related genes phenylalanine ammonia-lyase (PAL), chalcone synthase, chitinase (CHT), glucanase, and hydroxyproline-rich glycoprotein were examined in roots of dark red kidney bean (Phaseolus vulgaris L. cv Moncalm) colonized by the arbuscular mycorrhizal fungus Glomus intraradices Schenck & Smith. In three separate experiments the root length colonized ranged from 28 to 55% by 28 d after planting and inoculation. RNA blot analysis revealed little change in the accumulations of PAL, chalcone synthase, CHT, glucanase, and hydroxyproline-rich glycoprotein transcripts from the 28-d mycorrhizal roots compared to the uninoculated controls. Normalizing the ratios of defense-related transcript accumulation against RNA pools regarded as being constitutively expressed, actin mRNA, 25S rRNA, and 18S rRNA, indicated that changes in the ratios of up to 20% occur according to the RNA pool used for normalization. In situ hybridizations of colonized roots using probes for PAL and CHT showed that accumulations of both transcripts occurred only in arbusculated cells. Both young, finely branched arbuscules and older, clumped arbuscules displayed PAL and CHT message accumulations. The PAL and CHT mRNA accumulations were greater in cortical cells containing young arbuscules than in cells containing clumped arbuscules. Intercellular hyphae and vesicles elicited no response.
