Determination of gene copy number and genotype of transgenic Arabidopsis thaliana by competitive PCR.

Abstract excerpt

A simple and rapid method is described for determining the integrated T-DNA copy number and the genotype in transgenic Arabidopsis thaliana by two-step competitive PCR. First, the amount of genomic DNA in the extracts, obtained from an individual A. thaliana transformant, was accurately determined by the 1st competitive PCR using a known single copy gene, 4HPPD (4-hydroxyphenylpyruvate dioxygenase), as a target....
