How plants selectively silence jumping genes while protecting essential ones
Histone variants help establish DNA methylation at transposons (jumping genes) while preventing this epigenetic modification from spreading to essential genes in plants, a study from the Institute of Science Tokyo reveals.
AI Summary
Histone variants in plants direct DNA methylation to transposons, silencing these jumping genes while preventing the epigenetic mark from spreading to essential genes, according to researchers at the Institute of Science Tokyo. The study shows how chromosome‑associated proteins establish precise epigenomic patterns that protect genome stability.
