Recombination enhancement by replication (RER) in Rhizobium etli.
Studies in several organisms show that recombination and replication interact closely. Recombinational repair usually requires associated replication at some stage; moreover, additional replication can induce recombination through either homologous or illegitimate events. In prokaryotes, stimulation of recombination by replication is more dramatic when rolling circle replication is employed. In...
متن کاملNucleotide sequence of the Rhizobium etli nodS gene.
The complete nucleotide sequence of the nodS gene from the bean-nodulating Rhizobium etli, presumably encoding a methyltransferase, was determined. A phylogenetic analysis of five different NodS proteins from three genera of Gram- soil bacteria, Azorhizobium, Bradyrhizobium and Rhizobium, was performed.
