The Medicago truncatula MtRbohE gene is activated in arbusculated cells and is involved in root cortex colonization.
Article in Planta, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
MAIN
conclusionOur study demonstrated that the NAPDH oxidase gene MtRbohE is expressed in arbusculated cells and plays a role in arbuscule development. Plant NADPH oxidases, known as respiratory burst oxidase homologs (RBOH), belong to a multigenic family that plays an important role in the regulation of plant development and responses to biotic and abiotic stresses. In this study, we monitored the expression profiles of five Rboh genes (MtRbohA, MtRbohB, MtRbohE, MtRbohG, MtRbohF) in the roots of the model species Medicago truncatula upon colonization by arbuscular mycorrhizal fungi. A complementary cellular and molecular approach was used to monitor changes in mRNA abundance and localize transcripts in different cell types from mycorrhizal roots. Rboh transcript levels did not drastically change in total RNA extractions from whole mycorrhizal and non-mycorrhizal roots. Nevertheless, the analysis of laser microdissected cells and Agrobacterium rhizogenes-transformed roots expressing a GUS transcriptional fusion construct highlighted the MtRbohE expression in arbuscule-containing cells. Furthermore, the down regulation of MtRbohE by an RNAi approach generated an altered colonization pattern in the root cortex, when compared to control roots, with fewer arbuscules and multiple penetration attempts. Altogether our data indicate a transient up-regulation of MtRbohE expression in cortical cells colonized by arbuscules and suggest a role for MtRbohE in arbuscule accommodation within cortical cells.
