Rhizobium rhizogenes causes hairy roots, which are transgentic. Are the transgentic roots able to eventually grow normal roots or will they always be hairy in the transgenic organism?

After integration and expression, in vitro or under natural conditions, the hairy root phenotype is observed, which typically includes overdevelopment of a root system that is not completely geotropic, and altered (wrinkled) leaf morphology, if leaves are present. - Cardarelli M, Mariotti D, Pomponi M, Spanò L, Capone I, Costantino P. 1987. "Agrobacterium rhizogenes T-DNA genes capable of inducing hairy root phenotype". Molecular and General Genetics 209(3):475-480.

Is this permanent or temporary?
