Cytokinin induces expansin gene expression in Melilotus alba Desr. wild-type and the non-nodulating, non-mycorrhizal (NodMyc) mutant Masym3.
Article in Plant signaling & behavior, 2008. 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
We previously showed that applying 10(-6) M of the cytokinin 6-benzylaminopurine (BAP) to uninoculated roots of Masym3, a Nod(-)Myc(-)Melilotus alba (Desr.) mutant, resulted in the accumulation of MaENOD40 transcripts to levels similar to BAP-treated wild-type roots. In contrast, inoculation with a Nod(-)S. meliloti mutant expressing the trans-zeatin synthase gene of Agrobacterium tumefaciens (Nod(-)/pTZS(+)) did not induce MaENOD40 transcript accumulation in either wild-type or Masym3 roots. However, Masym3 root hairs became swollen at their tips following inoculation with wild-type or Nod(-)/pTZS(+) rhizobia. Because root hair distention and elongation are often correlated with increased expansin activity, we investigated whether BAP treatment or inoculation with Nod(-)/pTZS(+)S. meliloti upregulated the expression of expansin mRNAs. We first determined that treating wild-type roots with 10(-5) or 10(-6) M BAP resulted in greater MaEXPA1 transcript accumulation than treating roots with comparable concentrations of the auxin NAA. When Masym3 roots were treated with 10(-6) M BAP, MaEXPA mRNAs accumulated to levels comparable to wild-type roots. We then showed that MaEXPA1 mRNAs accumulated in wild-type M. alba roots in response to the Nod(-)/pTZS(+)S. meliloti strain. Masym3 mutant roots inoculated with Nod(-)/pTZS(+) rhizobia were also upregulated for MaEXPA1 expression.
