NodD1 and NodD2 Are Not Required for the Symbiotic Interaction of Bradyrhizobium ORS285 with Nod-Factor-Independent Aeschynomene Legumes.
Article in PloS one, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Photosynthetic Bradyrhizobium strain ORS285 forms nitrogen-fixing nodules on the roots and stems of tropical aquatic legumes of the Aeschynomene genus. Depending on the Aeschynomene species, this symbiotic interaction does or does not rely on the synthesis of Nod-factors (NFs). However, whether during the interaction of Bradyrhizobium ORS285 with NF-independent Aeschynomene species the nod genes are expressed and if the general regulator NodD plays a symbiotic role is unknown. Expression studies showed that in contrast to the interaction with the NF-dependent Aeschynomene species, A. afraspera, the Bradyrhizobium ORS285 nod genes are not induced upon contact with the NF-independent host plant A. indica. Mutational analysis of the two nodD genes present in ORS285, showed that deletion of nodD1 and nodD2 did not affect the symbiotic interaction between Bradyrhizobium ORS285 and A. indica whereas the deletions had an effect on the symbiotic interaction with A. afraspera plants. In addition, when the expression of nod genes was artificially induced by adding naringenin to the plant growth medium, the nodulation of A. indica by Bradyrhizobium ORS285 is delayed and resulted in lower nodule numbers.
