Selective Somatic Elimination of NICOTIANA GLUTINOSA Chromosomes in the F(1) Hybrids of N. SUAVEOLENS and N. GLUTINOSA.

abstract：:The rdgB mutants depend on recombinational repair of double-strand breaks. To assess other consequences of rdgB inactivation in Escherichia coli, we isolated RdgB-dependent mutants. All transposon inserts making cells dependent on RdgB inactivate genes of double-strand break repair, indicating that chromosomal fragmen...
