  •  Several Species Of Bacteria And Plants (1+ / 0-)

    There's plenty of evolutionary evidence to suggest there's a lot of this going on.

    http://en.wikipedia.org/...

    A. tumefaciens causes crown-gall disease in plants. The disease is characterised by a tumour-like growth or gall on the infected plant, often at the junction between the root and the shoot. Tumors are incited by the conjugative transfer of a DNA segment (T-DNA) from the bacterial tumour-inducing (Ti) plasmid. The closely related species, A. rhizogenes, induces root tumors, and carries the distinct Ri (root-inducing) plasmid. Although the taxonomy of Agrobacterium is currently under revision it can be generalised that 3 biovars exist within the genus, A. tumefaciens, A. rhizogenes, and A. vitis. .....

    The plasmid T-DNA is integrated semi-randomly into the genome of the host cell,[1] and the tumor morphology genes on the T-DNA are expressed, causing the formation of a gall. The T-DNA carries genes for the biosynthetic enzymes for the production of unusual amino acids, typically octopine or nopaline. It also carries genes for the biosynthesis of the plant hormones, auxin and cytokinins), and for the biosynthesis of opines, providing a carbon and nitrogen source for the bacteria that most other micro-organisms can't use, giving Agrobacterium a selective advantage.

      as I mention from time to time, I am quite averse to chlorophyll, so I try to avoid plants ( and even knowledge about plants as you can see) as much as I can!
