Resurrection of an ancestral gene: functional and evolutionary analyses of the Ngrol genes transferred from Agrobacterium to Nicotiana.

Journal of plant research - 1 Aug 2004

Abstract excerpt

The Ng rol genes, which have high similarity in sequence to the rol genes of Agrobacterium rhizogenes, are present in the genome of untransformed plants of Nicotiana glauca. It is thought that bacterial infection resulted in the transfer of the Ng rol genes to plants early in the evolution of the genus Nicotiana, since several species in this genus contain rol-like sequences but others do not. Plants transformed...
