Long-term preserved bean seeds exhibit high RNA integrity and high germination potential.
Article in Scientific reports, 2025. 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
Stored RNA plays a key role in seed germination, especially after seeds long-term storage. This study aimed to assess the correlation between germination potential (GP) and RNA integrity in common bean (Phaseolus vulgaris L.) seed accessions stored at -18 °C for 19.25 to 43.75 years and in seeds subjected to artificial aging at high temperature (42 °C) and relative humidity (100%). The GP of long-term preserved and artificially aged seed lots ranged from 3 to 100% and 38-87%, respectively. RNA integrity was evaluated using the RNA Integrity Number (RIN, Agilent Bioanalyzer software). RIN data suggested that: (1) Sample sizes for RIN analysis may need to vary based on the GP of the seeds; (2) RIN has the potential to predict physiological quality, especially in seeds with high GP; (3) RIN values by itself may not accurately reflect the rate of RNA degradation over time, necessitating comparison with a control to determine ΔRIN (the difference between the RIN values of the sample and the control); (4) ΔRIN has a significant positive correlation with GP. These findings highlight the potential of RNA integrity in seeds as a molecular marker for developing tests that complement germination tests.
