| WSs and ASs |
are ancient sequences mutually retained in |
Wm82 and AGH mtDNAs |
Glycine max |
| integrated viral sequences |
may contribute to |
evolution of the genome acting as sources of novel genetic material |
|
| repetitive sequences |
can be associated with |
chromosome rearrangements (CRs) such as inversion, deletion, duplication and translocations |
|
