Rearrangements of ribosomal DNA clusters in late generation telomerase-deficient Arabidopsis.
Original language description
The ends of eukaryotic chromosomes are capped with special nucleoprotein structures called telomeres. Telomere shortening due to telomerase inactivation may result in fusion of homologous or heterologous chromosomes, leading to their successive breakageduring anaphase movement, followed by fusion of broken ends in the next cell cycle, i.e. the breakage-fusion-bridge (BFB) cycle. Using fluorescence in situ hybridization (FISH) with 25S rDNA and specific bacterial artificial chromosome (BAC) probes we demonstrate participation of chromosomes 2 and 4 of Arabidopsis thaliana AtTERT null plants in the formation of anaphase bridges. Both homologous and non-homologous chromosomes formed transient anaphase bridges whose breakage and unequal separation led togenome rearrangement, including non-reciprocal translocations and aneuploidy.
