The cryptic plasmid of Agrobacterium tumefaciens cointegrates with the Ti plasmid and cooperates for opine degradation
MOLECULAR PLANT-MICROBE INTERACTIONS, 11(7), 583–591.

1997 journal article
A deletion in an indole synthase gene is responsible for the DIMBOA-deficient phenotype of bxbx maize
PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 94(24), 13345–13350.
MeSH headings : Benzoxazines; Chromosome Mapping; Gene Expression Regulation, Enzymologic; Kinetics; Mutation; Oxazines; Phenotype; Tryptophan / biosynthesis; Tryptophan Synthase / genetics; Zea mays / enzymology; Zea mays / genetics
TL;DR:
It is shown that feeding indole to bxbx seedlings restores their ability to synthesize DIMBOA, and it is proposed that the maize enzyme initially named tryptophan synthase alpha in fact is a DIM BOA biosynthetic enzyme, and this work proposes that it be renamed indole synthase.

TL;DR:
Crown gall tumours induced by four groups of Agrobacterium tumefaciens isolates were found to contain mannityl opine-related metabolites derived from condensation of glucose with glutamine followed by Amadori rearrangement.
