Abstract

The occurrence and levels of phytoecdysteroids in the seeds and other parts of plants grown from the seeds of 180 randomly selected plant species were assessed and compared. Ecdysteroids are frequently detectable in leaves and flowers, but less so in stems, roots and seeds. The seeds of 290 species were assessed for the presence of hydrolysable ecdysteroid conjugates. Low levels of conjugates were detected in a significant number of species, large amounts being present only when levels of free ecdysteroids were high. Individual plants of Arabidopsis thaliana were assessed for the presence of phytoecdysteroids. While plants of this species are generally ecdysteroid negative, individual plants in the population accumulate low levels of ecdysteroids. Extracts of seeds of 50 "ecdysteroid-negative" species were concentrated and partially purified to determine if they possess ecdysteroids at levels below the usual detection levels. Ecdysteroids were detectable by radioimmunoassay in almost all of these concentrated samples. Thus, all lines of evidence point to the conclusion that all species of plants have the capacity to produce at least low levels of phytoecdysteroids. This has important implications for the protection of crop species through enhancing ecdysteroid levels by breeding/genetic modification strategies.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In leaves of an even greater proportion of investigated plant species than seeds, ecdysteroids are present in detectable amounts.

    “They are present in detectable amounts in the seeds of 5-6% of investigated plant species and in leaves of an even greater proportion of species [2].”

  • Examination of many individuals of an ecdysteroid-negative species (Arabidopsis thaliana) found individual plants that contained low levels of ecdysteroids, even if the majority were negative.

  • Examination of the leaves of randomly selected species demonstrated that ca. 40% of the species contained at least low levels of ecdysteroids.

    From Ecdysteroids (2021) · cites this paper as [2]

  • Over 200 different ecdysteroids have been discovered in plants.

    “While 20-hydroxyecdysone (20HE) is the primary ecdysteroid found in arthropods, over 200 different ecdysteroids have been discovered in plants [6].”

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.
