Each is checked against this paper’s own text: does it say what the citing paper says it does?
In the citing paper
“In Spinacia oleracea roots, it has been found that PE production increases during pathogenic attack [21,22,149,150,151].”
From Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones (2022) · cites this paper as [150]
In the citing paper
“PEs provide plants tolerance against several soil nematodes and insects; thus, PE biosynthesis increases during mechanical wounding or pathogenic attack.”
From Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones (2022) · cites this paper as [150]
In the citing paper
“It has been found that wounding caused by pathogens increases accumulations of PEs in the roots, with signaling via an octadecanoic acid pathway or endogenous JA, resulting in enhanced resistance against subterranean herbivorous insects (Spodoptera exigua) and fungi [150].”
From Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones (2022) · cites this paper as [150]
In the citing paper
“It has been found that mechanically damaged roots showed a higher accumulation of 20-HE, by about 3-fold, within 2 days.”
From Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones (2022) · cites this paper as [150]
In the citing paper
“However, after 2 days, induction of PE concentration was identified in shoots.”
From Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones (2022) · cites this paper as [150]
In the citing paper
“In hydroponically grown spinach, increases in PE concentrations have been reported after MeJA application.”
From Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones (2022) · cites this paper as [150]
In the citing paper
“Thus, it was concluded that endogenous JA in the roots mediates signals during wounding and induces PE accumulation [150,193].”
From Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones (2022) · cites this paper as [150]
In the citing paper
“Nevertheless, shoot concentration was unchanged after Spodoptera exigua (insect) attack.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
