Expression of rice MATE family transporter OsMATE2 modulates arsenic accumulation in tobacco and rice.
Article in Plant molecular biology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 27 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
key messageThe OsMATE2 upon constitutive expression in tobacco decreases root-to-shoot As transfer coefficient and its endosperm-specific silencing in rice reduces grain As content, broadening the role of MATE proteins in planta. Rice (Oryza sativa) is capable of accumulating significant amount of arsenic (As) in grains, causing serious health hazard for rice consuming population. The multidrug and toxic compound extrusion (MATE) protein family comprises a large group of secondary transporters present universally in living organisms, and transports metabolites and/or xenobiotic compounds. OsMATE2, one of the MATE family members of rice was found to be transcriptionally up-regulated (sixfolds) in the developing seeds during As stress, and showed positive correlation with the As content in mature grains. Therefore, to understand the role of OsMATE2 in As accumulation, constitutive expression in tobacco was carried out. Transgenic tobacco plants exhibited decreased root-to-shoot As transfer coefficient (33.3-39.6%) along with augmented As sensitivity by increasing oxidative stress compared to untransformed control plants, indicating the involvement of OsMATE2 in As accumulation. Consequently, RNAi strategy was utilized for endosperm-specific silencing of endogenous OsMATE2 to mitigate As accumulation in rice grains. Transgenic rice lines demonstrated significant reduction of both OsMATE2 transcript (~ 38-87%) and grain As content (36.9-47.8%) compared to the control plants without undesirable effects on agronomical traits. Together, the present findings indicate the connection of OsMATE2 in As accumulation, and could expand the functional role of MATE proteins in planta.
