Transcriptional induction of two phosphate transporter 1 genes and enhanced root branching in grape plants inoculated with Funneliformis mosseae.

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 investigated the effects of the arbuscular mycorrhizal fungus (AMF) Funneliformis mosseae on the growth and root architecture of plantlets of the grape rootstock 41B MGt under hydroponic conditions, and analyzed the concomitant expression of putative mycorrhizal-specific phosphate transporter 1 (PHT1) genes. In vitro propagated plantlets were acclimatized to ex vitro culture before AMF inoculation and grown under low phosphate (Pi) nutrition conditions during 6 weeks. Grape roots could be efficiently colonized by F. mosseae in this culture system, as shown by high mycorrhization frequency and intensity. The presence of many arbuscules in the cortex was coupled with high-level expression of two PHT1 genes in grape roots. These two very similar genes, named VvPht1-1 and VvPht1-2, present P1BS and MYCS regulatory motifs in their promoter, consistent with a specific role in the mycorrhizal pathway of Pi uptake. Although AMF inoculation significantly increased shoot growth, no effect on root biomass was observed. However, inoculated grapes exhibited an enhanced branched root system compared with non-inoculated controls, with a twofold higher number of tips and a higher proportion of fine roots usually involved in nutrient uptake from the soil. Taken together, these results suggest that root colonization by F. mosseae improved grape growth by favoring the uptake of Pi from the substrate via VvPht1-1 and VvPht1-2 high-level expression.
