The role of sucrose in phosphate starvation response: transcriptomic and physiological insights in Arabidopsis Thaliana.
Article in BMC plant biology, 2025. 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
backgroundPi (inorganic phosphate) is an essential mineral nutrient and a key limiting factor for plant growth. Environmental factors of carbon and energy status provided by sucrose influence plant growth and stress adaption; however, the mechanisms by which plant seedlings cope with Pi-starvation stress in conjunction with these factors remain largely unknown.
resultsThis study investigates the interplay between sucrose status and Pi-starvation response using a combined Pi/sucrose treatment. Through comparative transcriptomic and physiological analyses, we demonstrated that: (1) the upregulation of anthocyanin biosynthesis under Pi-starvation is significantly attenuated under sucrose deficiency, coinciding with reduced anthocyanin and ROS (reactive oxygen species) accumulation; (2) photosynthesis is downregulated under Pi-starvation with sufficient sucrose supply but upregulated under sucrose limitation, with chlorophyll content decreasing under sufficient sucrose supply and increasing under deficiency; (3) ATP-consuming anabolic pathways are downregulated under Pi-starvation with sufficient sucrose supply but showed no significant changes under sucrose deficiency; and (4) plant-pathogen interaction pathways, typically upregulated during Pi-starvation, are downregulated under insufficient sucrose supply. Additionally, we identified PIF3 (phytochrome-interacting factor 3) as a potential regulator of Pi-starvation responses, with loss-of-function mutants exhibiting retarded growth and gain-of-function mutants showing enhanced growth under Pi-starvation.
conclusionThese results highlight the critical role of sucrose status in modulating plant Pi-starvation response and provide new insights into the adaptive mechanisms by which plants coordinate C/Pi balance to cope with nutrient stress, thus extending and complementing previous research on Pi-starvation response mechanisms.
