The intron of the pin Ⅱ gene in plasmid pBBB-pinⅡ had been deleted by Xba I restriction enzyme,and the modified plasmid (pBBB-pinIIM) were transferred into Agrobacteriwn tumefaciens C58.A spider insecticidal protein (SlP)gene were isolated from plasmid DNA of pBPCVH3 and inserted into the plasmid DNA of PSHIC which
caning gus and bar genes,Restriction enzyme digestion analysis showed recombinant pSHK-sIp were got
Cotyledons with Petiole from aseptic seedlings were used as e...
