title: Diversity of the limited-host range iaaH gene of Agrobacterium vitis strain Ag162.
abstract: The indole-3-acetamide hydrolase gene (iaaH) of the limited-host range strain AG162, a biotype III strain of Agrobacterium tumefaciens has been the subject of several studies and reviews, but its primary structure has not been previously reported. In the course of our own work we found that this gene hybridizes only weakly to a nucleic acid probe corresponding to the iaaH gene from a biotype I strain of A. tumefaciens. Analysis of the primary structure of the Ag162 iaaH gene revealed that it is diverse from biotype I iaaH genes and, surprisingly, also from the iaaH genes of previously characterized biotype III Agrobacterium strains.
