TL;DR: The earliest herbarium specimens of the allotetraploids (1949 and 1953) are used to represent the genomic condition near the time of polyploidization, and it is found that the parental rDNA repeats were inherited in roughly equal numbers.

TL;DR: Overall, only in tobacco is there any evidence that NCI may have influenced genome evolution, and here further data are required to verify chromosome identity.

TL;DR: Using slot-blot and fluorescent in situ hybridization (FISH), polymerase chain reaction experiments indicated that there are short lengths of the sequence TTTAGGG dispersed in the genome but that these sequences are almost certainly too short to act as functional telomeres even if they were at the chromosome termini.

TL;DR: The data together indicate that the establishment of pluripotency and cell proliferation occurring with callus induction is associated with enhanced ribosomal RNA gene expression and overall rDNA hypomethylation, but is not associated with material-enhanced relaxation of chromatin structure (decondensation) at rDNA loci.

TL;DR: It is demonstrated that in the Allium ancestor human-type telomeric repeats were lost from telomeres and were not replaced by any investigated alternative minisatellite repeats.
