Galactosides in the rhizosphere: Utilization by Sinorhizobium meliloti and development of a biosensor
Identifying the types and distributions of organic substrates that support microbial activities around plant roots is essential for a full understanding of plant–microbe interactions and rhizosphereExpand

Sinorhizobium meliloti mutants lacking phosphotransferase system enzyme HPr or EIIA are altered in diverse processes, including carbon metabolism, cobalt requirements, and succinoglycan production.
Sinorhizobium meliloti is a member of the Alphaproteobacteria that fixes nitrogen when it is in a symbiotic relationship. Genes for an incomplete phosphotransferase system (PTS) have been found inExpand

Control of inducer accumulation plays a key role in succinate-mediated catabolite repression in Sinorhizobium meliloti.
The symbiotic, nitrogen-fixing bacterium Sinorhizobium meliloti favors succinate and related dicarboxylic acids as carbon sources. As a preferred carbon source, succinate can exert cataboliteExpand

Characterization of a two-component regulatory system that regulates succinate-mediated catabolite repression in Sinorhizobium meliloti.
When they are available, Sinorhizobium meliloti utilizes C(4)-dicarboxylic acids as preferred carbon sources for growth while suppressing the utilization of some secondary carbon sources such as α-Expand

An AraC-like transcriptional activator is required for induction of genes needed for alpha-galactoside utilization in Sinorhizobium meliloti.
The nodulating bacterium Sinorhizobium meliloti can utilize alpha-galactosides like melibiose and raffinose as sole sources of carbon and energy. We show that this utilization requires an AraC-likeExpand
