dc.description.abstract | The nucleus architecture of hybrid crop plants is not a well-researched topic, yet it can
have important implications for their genetic stability and usefulness in the successful expression
of agronomically desired traits. In this work we studied the spatial distribution of introgressed
maize chromatin in oat maize addition lines with the number of added maize chromosomes
varying from one to four. The number of chromosome additions was confirmed by genomic in situ
hybridization (GISH). Maize chromosome-specific simple sequence repeat (SSR) markers were used
to identify the added chromosomes. GISH on 3-D root and leaf nuclei was performed to assess the
number, volume, and position of the maize-chromatin occupied regions. We revealed that the maize
chromosome territory (CT) associations of varying degree prevailed in the double disomic lines,
while CT separation was the most common distribution pattern in the double monosomic line. In all
analyzed lines, the regions occupied by maize CTs were located preferentially at the nuclear periphery.
A comparison between the tissues showed that the maize CTs in the leaf nuclei are positioned closer
to the center of the nucleus than in the root nuclei. These findings shed more light on the processes
that shape the nucleus architecture in hybrids. | pl_PL |
