Abstract

The study of epigenetics in plants has a long and rich history, from initial descriptions of non-Mendelian gene behaviors to seminal discoveries of chromatin-modifying proteins and RNAs that mediate gene silencing in most eukaryotes, including humans. Genetic screens in the model plant Arabidopsis have been particularly rewarding, identifying more than 130 epigenetic regulators thus far. The diversity of epigenetic pathways in plants is remarkable, presumably contributing to the phenotypic plasticity of plant postembryonic development and the ability to survive and reproduce in unpredictable environments.

  • Deposition of H3K4me3 at the 5' regions of actively transcribed genes is facilitated by trithorax group (trxG) protein complexes in coordination with the initiating form of RNA polymerase.

    “The deposition of H3K4me3 at the 5 ′ regions of actively transcribed genes is facilitated by trithorax group (trxG) protein complexes in coordination with the initiating form of RNA polymerase [56,57].”

    From Somaclonal Variation and Clonal Fidelity in Commercial Micropropagation: Challenges and Perspectives (2025) · cites this paper as [56]

    Section 2.2.2 (page unavailable) says the TRX-family protein ATX1 can catalyze H3K4 methylation, while section 3.5.3 (page unavailable) identifies H3K4me3 as typical of actively transcribed loci. Neither passage establishes deposition specifically at genes’ 5′ regions or coordination of trxG complexes with initiating RNA polymerase. (LLM, conf=0.86)

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.
