Rhizobia are some of the best-studied plant microbiota. These oligotrophic
Alphaproteobacteria or Betaproteobacteria form symbioses with their legume hosts …

Bacterial accessory genes are genomic symbionts with an evolutionary history and future
that is different from that of their hosts. Packages of accessory genes move from strain to …

Integrative and conjugative elements (ICEs) are widespread mobile DNA that transmit both
vertically, in a host-integrated state, and horizontally, through excision and transfer to new …

Genetic decoding is not 'frozen'as was earlier thought, but dynamic. One facet of this is
frameshifting that often results in synthesis of a C-terminal region encoded by a new frame …

Rhizobia are one of the most important and best studied groups of bacterial symbionts. They
are defined by their ability to establish nitrogen-fixing intracellular infections within plant …

Soil-dwelling bacteria collectively referred to as rhizobia synthesize and perceive N-acyl-
homoserine lactone (AHL) signals to regulate gene expression in a population density …

Horizontal gene transfer (HGT) of genomic islands is a driving force of bacterial evolution.
Many pathogens and symbionts use this mechanism to spread mobile genetic elements that …

Integrative and conjugative elements (ICEs) are ubiquitous mobile genetic elements present
as “genomic islands” within bacterial chromosomes. Symbiosis islands are ICEs that convert …

Members of the Mesorhizobium genus are soil bacteria that often form nitrogen-fixing
symbioses with legumes. Most characterised Mesorhizobium spp. genomes are~ 8 Mb in …

Establishment of the symbiotic relationship that develops between rhizobia and their legume
hosts is contingent upon an interkingdom signal exchange. In response to host legume …
