The aims of this study were to functionally characterize and analyze the transcriptional regulation and transcriptome of the Rhizobium etli rpoE4 gene. An R. etli rpoE4 mutant was sensitive to oxidative, saline, and osmotic stresses. Using transcript

The basic replicon of Rhizobium etli CE3, like other members of the repABC plasmid family, is constituted by the repABC operon. RepC is essential for replication, and RepA and RepB play a role in plasmid segregation. It has been shown that deletion d

A collection of Rhizobium etli promoters was isolated from a genomic DNA library constructed in the promoter-trap vector pBBMCS53, by their ability to drive the expression of a gusA reporter gene. Thirty-seven clones were selected, and their transcri

In the human pathogen Pseudomonas aeruginosa, betaine aldehyde dehydrogenase (BADH) may play a dual role assimilating carbon and nitrogen from choline or choline precursors--abundant at infection sites--and producing glycine betaine, which protects t

The repABC replicons contain an operon encoding the initiator protein (RepC) and partitioning proteins (RepA and RepB). The latter two proteins negatively regulate the transcription of the operon. In this article we have identified two novel regulato

The basic replicon of the symbiotic plasmid (p42d) of Rhizobium etli CE3 is constituted by the repABC operon. Whereas RepC is essential for plasmid replication, RepA and RepB are involved in plasmid partitioning. Three incompatibility regions have be

Summary: The replicator region of the symbiotic plasmid of Rhizobium etli CFN42 was cloned and sequenced. A plasmid derivative (pH3) harbouring a 5.6 kb HindIII fragment from the symbiotic plasmid was found to be capable of independent replication an

The physiological role and transcriptional expression of Rhizobium etli sigma factors rpoH1 and rpoH2 are reported in this work. Both rpoH1 and rpoH2 were able to complement the temperature-sensitive phenotype of an Escherichia coli rpoH mutant. The

Bacteria of the order Rhizobiales are able to establish nitrogen-fixing symbioses with legumes. Commonly, genes for symbiosis are harbored on large symbiotic plasmids. Although the transfer of symbiotic plasmids is commonly detected in nature, there
