Ribosomal gene variation in soybean (Glycine) and its relatives
1L. H. Bailey Hortorium, Cornell University, 14853, Ithaca, NY, USA.
Abstract:
The genes encoding the 18S∶25S ribosomal RNA gene repeat in soybean (Glycine max) and its relatives in the genus Glycine are surveyed for variation in repeat length and restriction enzyme site locations. Within the wild species of subgenus Glycine, considerable differences in repeat size occur, with a maximum observed in G. falcata. Repeat length and site polymorphisms occur in several species, but within individual plants only single repeat types are observed. The rDNA of the cultivated soybean and its wild progenitor, G. soja are identical at the level of this study, and no variation is found in over 40 accessions of the two species. Data from rDNA mapping studies are congruent with those of previous biosystematic studies, and in some instances give evidence of divergences not seen with other approaches.

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
