Rapid evolution of parental rDNA in a synthetic tobacco allotetraploid line.

Original language description

In this paper we have shown amplification of rDNA variants derived from N. tomentosiformis parent in the synthetic tabacco Th37, 4n (N. sylvestris x N. tomentosiformis) line. Amplification was correlated with occurance of a novel rDNA locus on N. tomentosiformis-derived chromosome T4. Combined with an analysis of tobacco cultivars, the data indicate that an initial burst rDNA evolution associated with allopolyploidy was followed by a slower process that led towards reduced complexity and a decreased number of rDNA variants.
