The core subunits of the complex are members of the SMC2 (Structural Maintenance of Chromosomes) and SMC4 gene families. We have cloned ... A second, highly homologous SMC2 gene, AtCAPE-2, was identified by the Arabidopsis genome project. SMC2 gene expression in Arabidopsis was correlated with the mitotic activity of tissues,

This mechanism relies on (epigenetic) interactions among three dTph1 copies on the two homologous chromosomes and results in elimination of a dTph1 insertion without leaving a footprint.

If interactions such as recombination and gene conversion occur between the ends of non-homologous chromosomes, patches of subtelomeric sequence ... Together, these results suggest that the Alu insertion and the 881 bp deletion co-segregate. The Alu insertion/881 bp deletion combination was observed on chromosomes 5q, 8p,
