Photosynthetic Efficiency and Proteome Response of Diploid and Polyploid
Article in Genes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Global warming and soil salinization pose significant challenges to modern plant cultivation. BACKGROUND/
objectivesPolyploidization of whole-genome duplication is an important evolutionary strategy, enhancing plant adaptation to environmental stress. This study investigates the impact of heat and salt stress on photosynthesis and proteomic changes in a polyploid series of
methodsTwo-month-old plants were exposed to heat stress (45 °C for 3 h) or salt stress (300 mM NaCl for 24 or 48 h). Stress effects were assessed via photosystem II maximum efficiency (
resultsOur findings revealed that polyploid plants maintained higher photosynthetic performance than diploids under both heat and salt stress. While proline accumulation under heat stress was comparable across all ploidy levels, polyploids accumulated more proline under salt stress, indicating enhanced salinity tolerance. Proteomic analysis showed differential protein expression among diploid and polyploid plants in response to stress. Several differentially expressed proteins had functions involved in photosynthesis and stress response pathways. These findings confirm prior evidence of tetraploid Arabidopsis resilience to salinity and extend this observation to heat stress. Moreover, triploids also demonstrated increased stress tolerance, suggesting adaptive advantages of this intermediate ploidy level as well.
conclusionsDifferential expression patterns among ploidy levels may reflect varied energy-saving strategies and alterations in protein structure and function. This work highlights the importance of polyploidy in improving plant stress resilience, offering insights for breeding stress-tolerant crops in a changing climate.
