Hi all,

The process of preventing the tomatoes from softening is to introducing 
an antisense gene against polygalactronase into the nucleus? I am very 
unclear on a few points, is 
the antisense gene genetically engineered into the DNA of the tomatoes by 
using the Agrobacterium method? How is the gene then "switch off"? As 
refered by the books --- " ... by switching the gene on and off..."
