The Plant Oncogenes rolA, B, and C from Agrobacterium rhizogenes: Effects on Morphology, Development, and Hormone Metabolism
Abstract
The soil pathogen Agrobacterium rhizogenes is the etiological agent of hairy root disease and can incite tumor formation on many dicotyledonous plants (1). The disease is so-called because abundant fine roots that resemble hair develop at the site of infection. A segment of the large Ri plasmid, the T-DNA or transferred DNA, is mobilized from the bacterium into the plant genome, thereby initiating the disease (24). The T-DNA may consist of one region (e.g., Ri plasmid 8196) or two separate regions, termed the TL-DNA and the TR-DNA. Axenic growth of transformed roots in liquid culture is typically fast, highly branched, and hormone independent.
