Transcription factors in phosphorus utilization: enhancing crop productivity and stress resilience.
Review in Planta, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
MAIN
conclusionTranscription factors coordinate phosphorus sensing, transport, remobilization, and stress adaptation, providing actionable molecular targets for breeding crops with higher phosphorus-use efficiency, productivity, and resilience. Phosphorus (P) scarcity in soils limits crop productivity, demanding genotypes that sense and acquire inorganic phosphate (Pi) efficiently and use it prudently. This review synthesizes recent advances on transcription factors (TFs) that coordinate Pi acquisition and phosphorus economy in plants. Central MYB/PHR modules (e.g., PHR1 and homologs) activate phosphate-starvation programs via P1BS-containing targets, while WRKY factors remodel stress and nutrient responses through W-box-driven networks. Together with bHLH and hormone-associated TFs (ARF, ERF), these regulators: (1) directly modulate high-affinity Pi transporters (PHT1 family), (2) reconfigure root system architecture by balancing primary-root inhibition with lateral root and root-hair proliferation, (3) enhance rhizosphere mobilization via organic-acid and acid phosphatase secretion, and (4) promote arbuscular mycorrhizal-mediated Pi uptake. TFs also integrate hormone cues (jasmonate, ethylene, strigolactone, brassinosteroid, auxin/cytokinin) and nutrient crosstalk (notably N-P via PHR-SPX and NIGT cascades) to align local foraging with whole-plant status. Beyond acquisition, PHR-centered circuits contribute to phosphorus use efficiency by guiding lipid remodeling and directing Pi translocation and remobilization. Translational studies highlight the promise of TF-based engineering: manipulating factors, such as OsPHR2, TaPHR1, OsWRKY74, and ZmPTF1, improves Pi uptake, biomass, and yield under low-Pi conditions. We conclude that precise TF deployment and cis-regulatory tuning offer a scalable path to crops with higher Pi efficiency and reduced fertilizer dependence, advancing sustainable agriculture and food security.
