Hexofuranosides are widely spread in nature, and notably in numerous pathogenic
microorganisms. This particular five-membered ring for hexosides leads to novel biological …

Agrobacterium tumefaciens incites the formation of readily visible macroscopic structures
known as crown galls on plant tissues that it infects. Records from biologists as early as the …

Phosphorous-containing molecules are essential constituents of all living cells. While the
phosphate functional group is very common in small molecule natural products, nucleic …

The first reports on opines date back to the midfifties, when Morel (1956) and Lioret (1956)
independently presented their results on, respectively, the metabolism of arginine and the …

We report four new opines that have been discovered in sterile crown gall tumour tissue.
These compounds have been partially characterised as phosphorylated sugar derivatives …

Agrobacterium radiobacter strain K84 is used commercially for the biological control of
crown gall. It contains the conjugative plasmid pAgK84, which encodes the synthesis of …

Agrobacterium radiobacter K84, used worldwide to biocontrol crown gall disease caused by
Agrobacterium tumefaciens, produces an antiagrobacterial compound called agrocin 84. We …

The conjugative behaviour of nopaline and agropine Ti-plasmids has been investigated.
Using a technique which avoids enrichment of transconjugants on a mating medium we …

Agrobacterium is a genus of soil bacteria with the ability to transform plant cells by a T-DNA-
sequence located on the pTi/pRi-plasmid containing a set of genes expressed in plant cells …

Strain K84 of Agrobacterium (formerly called A. radiobacter) has been a successful
biocontrol agent of crown gall disease for almost 30 years all over the world. In spite of its …
