In Vivo Modulation of T-DNA Encoded Amidohydrolase Activity in Transformed Tobacco Cells.


Auxin autonomous growth of most crown gall tumor cells requires the expression of two auxin biosynthesizing genes (tms 1 and tms 2) from the T-DNA of Agrobacterium tumefaciens. The potential role of the tms 2 locus to affect auxin accumulation was studied by measuring the activity of its gene product, indoleacetamide hydrolase (AH), in cloned cells of… (More)
