Plant 45S rDNA clusters are fragile sites and their instability is associated with epigenetic alterationsSCOPUS
PloS one, Volume 7, Issue 4, 2012, Pages e35139-e35139.
Our previous study demonstrated that 45S ribosomal DNA (45S rDNA) clusters were chromosome fragile sites expressed spontaneously in Lolium. In this study, fragile phenotypes of 45S rDNA were observed under aphidicolin (APH) incubation in several plant species. Further actinomycin D (ActD) treatment showed that transcriptional stress might...More
