Murine toxicit of Agrobacterium tumefaciens.

Stimulation of Agrobacterium tumefaciens Growth by Azotobacter vinelandii Ferrisiderophores.

Azotobacter vinelandii stimulated the growth of Agrobacterium tumefaciens H2, H23, H24, H27, and ATCC 15955 on media containing insoluble iron sources. The Azotobacter vinelandii siderophores appeared to promote Agrobacterium tumefaciens growth by solubilizing mineral iron, and the ferrisiderophores so formed then acted as iron sources for Agrobacterium tumefaciens. Agrobactin, the Agrobacteriu...

Expression of Cauliflower Mosaic Virus Proteins from an Integrated Form of the Viral Genome

The expression of cauliflower mosaic virus proteins was examined in crown gall tissue transformed by integration of virus genome DNA into plant host chromosomes by Agrobacterium tumefaciens-mediated transfer. Galls upon plants of species that support infection by virus particles as well as upon non-host plants were analysed by immunoblotting using antisera specific to proteins encoded by viral ...

Characterization of a non-ribosomal peptide from agrobacterium tumefaciens

Genome Sequence of the Octopine-Type Agrobacterium tumefaciens Strain Ach5

We have sequenced the complete genome of the plant pathogen Agrobacterium tumefaciens strain LBA4213, a derivative of the wild-type strain A. tumefaciens Ach5 and the ancestor of A. tumefaciens strain LBA4404 used in genetic engineering. The genome consists of a circular chromosome and a linear chromosome, as well as a megaplasmid and a tumor-inducing plasmid.

Agrobacterium Mediated Transformation of Maize (Zea mays L.)

Agrobacterium tumefaciens mediated transformation may offer a better alternative than the biolistic gun for genetic transformation of maize plants. This gene delivery system results in a greater proportion of stable, low-copy number transgenic events than does the biolistic gun, and is highly efficient. In the present work, we studied maize transformation using A. tumefaciens by identifying som...
