Other claims from this paper (6)
- Observation A complete map of centromeric satellite repeats was generated from three telomere-to-telomere soybean genomes.
- Observation Consensus motifs associated with CENH3-binding sites were identified in centromeric satellite repeats.
- Observation CentGm-1 and CentGm-4 evolve independently.
- Observation Completely identical CentGm-4 sequences consistently appear on the same chromosome across different soybean varieties, indicating chromosome-specific preference.
- Observation Both CentGm-1 and CentGm-4 contain similar motifs with potential to bind CENH3 protein.
- Mechanism The authors propose that replication templates in the centromere originate from multiple CENH3-nucleosome complexes bound to CentGm sequences.
