title: Variability of the 5'-end of the large subunit rDNA and presence of a new short class of rRNA in Rhizobiaceae.
abstract: A highly variable region of DNA was found between positions 115 and 388 (Escherichia coli numeration) of the large subunit (ls) rRNA genes of 55 rhizobial and agrobacterial strains. In each case this heterogeneity was accompanied by the presence of a new rRNA species approximately 130 bp long. This novel rRNA species corresponded to the 5'-end of the ls rRNA genes. An additional rRNA processing site was located in the central region of the remaining ls rRNA of many of the Rhizobium leguminosarum and Rh. etli strains, and in all of the agrobacteria studied, excepting the type strain of Agrobacterium vitis NCPPB 3554 and Agrobacterium sp. strain ChAg4.
