Isolation by PCR-based methods of a plant antifungal polygalacturonase-inhibiting protein gene

A polygalacturonase-inhibiting protein (pgip) gene from Malus domestica cv Granny Smith apple fruit was cloned by degenerate oligo-primed polymerase chain reaction (PCR) and Inverse PCR. An alignment of the pear and bean PGIP sequences was used to design degenerate PCR primers in highly conserved re...
