Incompatibility between a Rhizobium Sym plasmid and a Ri plasmid of Agrobacterium

Michael O'ConnellA Puehler


The symbiotic plasmid of Rhizobium trifolii G1008 was mobilized to other Rhizobium strains and to Agrobacterium using Tn5-Mob, a transposon that confers on a host replicon the ability to be mobilized in trans by RP4. Incompatibility was observed between pSymG1008 and the hairy-root-inducing plasmid pRi1855. Agarose gel electrophoresis revealed that pRi1855 was eliminated as an autonomous element in the presence of pSymG1008 and its absence was correlated with loss of the ability to induce hairy root disease. This indicates a close ancestral relationship between a Rhizobium symbiotic plasmid and a plant pathogenic plasmid of Agrobacterium. pSymG1008 and pRi1855 can be assigned to the IncRh-3 incompatibility group. Furthermore, pSymG1008 was mobilized at low frequency to R. phaseoli 51E and the transconjugants isolated had lost the indigenous Sym plasmid and the ability to nodulate beans.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
