Genetic and molecular organization of ribosomal DNA (rDNA) variants in wild and cultivated barley.

Genetics - 1 Nov 1990

Allard R W, Saghai Maroof M A, Zhang Q, Jorgensen R A

Abstract excerpt

Twenty rDNA spacer-length variants (slvs) have been identified in barley. These slvs form a ladder in which each variant (with one exception) differs from its immediate neighbors by a 115-bp subrepeat. The 20 slvs are organized in two families, one forming an eight-step ladder (slvs 100-107) in the nucleolus organizer region (NOR) of chromosome 7 and the other a 12-step ladder (slvs 108a-118) in the NOR of...
