Phosphate deficiency reduces nodule formation through a phosphate starvation response-like protein in Phaseolus vulgaris.

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
Phosphate deficiency reduces nodule formation in various legumes, which hinders nitrogen fixation and crop yield. We previously showed that phosphate deficiency reduces nodule formation by activating the autoregulation of nodulation (AON) pathway. We also observed that some genetic components of the AON pathway contain Phosphate Starvation Response 1 binding site cis-regulatory elements in their promoter regions, which are recognized by the Phosphate Starvation Response 1 transcription factor. This evidence led us to hypothesize that host plant phosphate levels regulate the expression of genes essential for forming nodules through a PHR-Like protein. In the present study, we provide evidence supporting the participation of PvPHR-Like 7 (PvPHR-L7) in regulating nodule formation in Phaseolus vulgaris. Modulation of PvPHR-L7's expression by RNA interference and overexpression suggested that this transcription factor may control the expression of crucial symbiotic genes involved in nodule development in P. vulgaris. An RT-qPCR analysis revealed that the expression of PvPHR-L7, PvNIN, and PvTML is regulated in accordingly to the plant host Pi levels. Transactivation assays in Nicotiana benthamiana and P. vulgaris transgenic roots indicate that PvPHR-L7 can upregulate the expression of PvNIN and PvTML in the absence of rhizobia. In contrast, PvPHR-L7 downregulates the expression of PvNIN under symbiotic conditions with rhizobia. The data presented shed light on the potential role that PvPHR-L7 plays in the root nodule symbiosis.
