Highly repetitive sequences in B chromosomes of Secale cereale revealed by fluorescence in situ hybridization
1994
Cuadrado, A. | Jouve, N.
An analysis of the presence and distribution of the rye and wheat repeated sequences in rye B chromosomes was carried out by fluorescent in situ hybridization. Probes used consisted of three highly repetitive sequences from rye (psc 119.2, psc74, and psc34) and the multigene families for the 25S-5.8S-18S and 5S rDNA from wheat (pTa71 and pTa794, respectively). pSc74 and pSc119.2 showed hybridization signals in the telomeric regions of rye B chromosomes. The remaining DNA clones did not hybridize to the B chromosomes
