Summary: Fragile sites (FS) are reported in the 45S rDNA containing NOR region of Lofium species, likely resulting in breaks and chromosomal lesions™ 2. If not repaired such breaks could generate fragments and cause the loss of genetic material and genomic instability’. The formation of neocentromeres could prevent the loss of chromosome fragments.
