Satellite DNA-targeted CRISPR/Cas9-mediated editing enables chromosome truncation and elimination in wheat.
Chen J, Liu T, Xia Y, Barth L, Plieske J
Summary
PubMedScientists used a precision gene-editing tool (CRISPR/Cas9) to deliberately remove entire chromosomes from wheat by targeting repetitive DNA sequences found only on those chromosomes. This breakthrough could help breeders eliminate unwanted genetic material from wheat more efficiently than traditional methods.

Key Findings
CRISPR/Cas9 targeted at satellite DNA (highly repetitive chromosome-specific sequences) successfully induced chromosome truncation and complete elimination in wheat
The approach exploits repetitive satellite DNA as a unique genomic address to direct editing tools to specific chromosomes, enabling large-scale chromosomal engineering
Chromosome elimination was achieved in wheat, a complex polyploid crop, demonstrating feasibility in genomes with multiple similar chromosome sets

Species Mentioned
Wheat is a group of wild and domesticated grasses of the genus Triticum. As cereals, they are cultivated for their grains, which are staple foods around the world. Well-known wheat species and hybrids include the most widely grown common wheat, spelt, durum, emmer, einkorn, and Khorasan or Kamut....
