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

Seed storability is crucial for maintaining vigor at the sowing stage and ensuring agricultural sustainability. Although molecular chaperones are well characterized in protein homeostasis, their roles in regulating ABA receptor stability and starch integrity during seed aging remain unclear. Here, we demonstrate that OsCPN10a enhances storability by maintaining ABA homeostasis, suppressing ROS accumulation, and preserving starch granule structure. Genetic and biochemical analyses reveal that OsCPN10a functions upstream of the OsCPN20-OsHSP60-3B cascade, directly interacts with both partners to promote complex assembly, and negatively regulates ABA signaling. The resulting trimeric complex interacts with OsPYL10, facilitating receptor dissociation and high-affinity association with the PP2C phosphatase OsABIL1 to attenuate signaling. This study reveals a non-canonical function of molecular chaperones in directly modulating hormone receptor signaling, establishing a mechanistic link between protein homeostasis and ABA sensitivity in seeds.
