1 · What the graph read from it

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.

2 · The registry

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

Pseudomonas-based biofertilizers show strong potential in sustainable agriculture; however, their effects on rice growth and nutrient acquisition under organic fertilization remain insufficiently characterized. This study evaluated the effects of Pseudomonas atacamensis SJA1 (CGMCC No. 26128) on rice growth and nutrient accumulation using a pot experiment with four treatments: organic fertilizer (CK), SJA1 inoculation (S), mixed commercial biofertilizer (MC, Bacillus subtilis and Pseudomonas atacamensis), and a combination of organic fertilizer, SJA1 inoculation, and commercial biofertilizer (SC). Plant biomass and nutrient content were measured, and the expression of nutrient-related genes (OsMGD2, OsMGD3, OsPHO2, OsPHR2, OsSAE1a, and OsSIZ2) in leaves and roots was analyzed using qRT-PCR. Whole-genome sequencing and functional annotation of SJA1 were conducted to identify traits associated with plant growth promotion. SJA1 inoculation significantly increased root biomass and enhanced phosphorus accumulation and increased nitrogen accumulation particularly in roots. SJA1 inoculation strongly induced the expression of several phosphorus- and nutrient-responsive genes in roots, including OsPHR2, OsPHO2, OsSAE1a, OsSIZ2, and OsMGD3. Genomic analysis identified genes in SJA1 associated with phosphate solubilization (e.g., gcd and the pqq operon), nitrogen metabolism, and rhizosphere colonization. These results indicate that SJA1 enhances root development and phosphorus accumulation in rice under organic fertilization, and suggest potential roles in plant nutrient acquisition, although the underlying processes require further validation.
