Analysis of two abundant, highly related satellites in the allotetraploid Nicotiana arentsii using double-strand conformation polymorphism analysis and sequencing
Original language description
In allotetraploid Nicotiana arentsii, we examined the fate of homologous subtelomeric satellites NUNSSP and NWISSP inherited from diploid progenitors N. undulata and N. wigandioides, respectively. While the NUNSSP monomers were highly homogeneous in nucleotide sequences, the NWISSP monomers formed two separate clades. Likewise, the genomic NUNSSP monomers showed less DNA conformation heterogeneity than NWISSP monomers, with distinct conformations. Sequence, structural and chromosomal features of the parental satellites were faithfully inherited by N. arentsii. Our study revealed that inter-genomic homogenisation of subtelomeric satellite repeats does not occur in N. arentsii allotetraploid. We propose that the sequence and structural divergence of subtelomeric satellites may render allopolyploid chromosomes less vulnerable to intergenomic exchanges.
