Disclosed herein are assays for detecting the presence of a
lysine-increasing transgenic event based on the DNA sequence of the
exogenous DNA construct inserted into the maize genome and of genomic
sequences flanking the insertion site. Also provided are transgenic
plants having a novel exogenous DNA construct that expresses a
dihydrodipicolinic acid synthase, the activity of which results in
increased lysine in a plant or plant product.
