Abstract excerpt
Fluorescence in-situ hybridization (FISH) of total genomic and repetitive DNA on microsporocytes of ditelocentric addition lines of rye 5RL in hexaploid wheat was performed to study the behaviour of the rye homologous chromosome arms in relation to centromere and telomere dynamics at premeiotic interphase and meiotic prophase I. By comparing isogenic lines with and without the Ph1 locus, we established the effect...
