| molecularNote | The entire coding region was replaced by a construct containing a beta-geo fusion gene, lacking a promoter. Recombination of the construct left the 5' flanking region intact, enabling the expression of the beta-geo transgene to be under the control of the endogenous promoter and regulatory sequences. |
