Abstract: Aimed to study the function of polygalacturonase-inhibiting protein gene in plant,breed disease resistant cultivar,obtain the transgenic plant,a plant expression vector pWR306-PGIP was constructed by inserting the PGIP gene coding fragment from cloning vector pMD-18T by SalⅠand BamHⅠsites into pWR306 between of ED35s promotor and NOS terminator. The identification results showed that the plant expression vector pWR306-PGIP and Agrobacterium tumefaciems were constructed successfully. Subsequently PGIP gene was transformed into Zhongshu No. 4 tomato leaves and shoot fragments mediated by Agrobacterium tumerfaciens. Eight transgenic resistant plants were proved by PCR preliminarily that the PGIP gene had integrated into tomato genome

Key words: PGIP gene, Plant expression vector, Agrobacterium tumerfaciens, Genetic transformation, Tomato
