A significant proportion of bacteria express two or more chaperonin genes. Chaperonins are
a group of molecular chaperones, defined by sequence similarity, required for the folding of …

It is well established that soil is a challenging environment for bacteria, where conditions
may change rapidly and bacteria have to acclimate and adapt in order to survive. Rhizobia …

Sinorhizobium meliloti genes transcriptionally up-regulated after heat stress, as well as upon
entry into stationary phase, were identified by microarray analyses. Sixty stress response …

Sinorhizobium meliloti can live as a soil saprophyte and can engage in a nitrogen-fixing
symbiosis with plant roots. To succeed in such diverse environments, the bacteria must …

Citrus greening disease, also known as huanglongbing (HLB), is the most devastating
disease of Citrus worldwide. This incurable disease is caused primarily by the bacterium …

Background Environmental pH stress constitutes a limiting factor for S. meliloti survival and
development. The response to acidic pH stress in S. meliloti is versatile and characterized …

Rhizobia are soil bacteria able to form symbioses with legumes and fix atmospheric
nitrogen, converting it into a form that can be assimilated by the plant. The biological …

Many bacterial species contain multiple copies of the genes that encode the chaperone
GroEL and its cochaperone, GroES, including all of the fully sequenced root-nodulating …

Background Quorum sensing (QS) in Sinorhizobium meliloti involves at least half a dozen
different N-acyl homoserine lactone (AHL) signals. These signals are produced by SinI, the …

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 …
