Expression Analysis of PIN Genes in Root Tips and Nodules of Medicago truncatula.
Article in International journal of molecular sciences, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
Polar auxin transport is dependent on the family of PIN-formed proteins (PINs), which are membrane transporters of anionic indole-3-acetic acid (IAA(-)). It is assumed that polar auxin transport may be essential in the development and meristematic activity maintenance of Medicago truncatula (M. truncatula) root nodules. However, little is known about the involvement of specific PIN proteins in M. truncatula nodulation. Using real-time quantitative PCR, we analyzed the expression patterns of all previously identified MtPIN genes and compared them between root nodules and root tips of M. truncatula. Our results demonstrated significant differences in the expression level of all 11 genes (MtPIN1-MtPIN11) between examined organs. Interestingly, MtPIN9 was the only PIN gene with higher expression level in root nodules compared to root tips. This result is the first indication of PIN9 transporter potential involvement in M. truncatula nodulation. Moreover, relatively high expression level in root nodules was attributed to MtPINs encoding orthologs of Arabidopsis thaliana PIN5 subclade. PIN proteins from this subclade have been found to localize in the endoplasmic reticulum, which may indicate that the development and meristematic activity maintenance of M. truncatula root nodules is associated with intracellular homeostasis of auxins level and their metabolism in the endoplasmic reticulum.
