Temporal and spatial regulation of the symbiotic genes of Rhizobium meliloti in planta revealed by transposon Tn5-gusA.

Genes & development - 1 Mar 1990

Sharma S B, Signer E R

Abstract excerpt

Tn5-gusA promoter/probe transposons have been constructed that fuse the Escherichia coli gusA reporter gene transcriptionally or translationally with a target promoter. These have been used to monitor expression of Rhizobium meliloti symbiotic genes within alfalfa nodules. Fusions in all 11 nod genes studied show the same pattern of expression: first on the root surface, then throughout the developing nodule,...
