B-02 Germ-Responsive Promoter for Plant

Technology Benefits

ΓùÅ Transgenic plants can be produced by using its own genesΓùÅ It is environmental friendlyΓùÅ It will not induce an allergy in consumers

Technology Application

ΓùÅ By employing any gene involved in protective response, it allows creation of a pathogen-resistant plant which has a prompt protective response to pathogen infectionΓùÅ It can be applied for biomass plant production

Detailed Technology Description

Researchers at Nagoya University have found that Potato Vetispiradiene 3 (PVS3), one of the genes involved in production of phytoalexin, was significantly expressed after inoculation with either compatible or incompatible species. a) Pathogen resistant transgenic potato was produced by introducing an activated form of protective signal transduction enzyme (stMEK1DD) linked to PVS3 promoter. While control potato was effected greatly by pathogen, transgenic potato grew normally. b) Oxidative-stress resistant transgenic potato was produced by introducing an activated form of Ca+-dependent protein kinase (CA-CDPK) linked to PVS3 promoter. Transgenic potato showed a great resistance to pathogen.

Title: Germ-responsive promoter
Usefulness: Germ-responsive promoter
Summary: (V) is useful for producing a transformed plant, which involves transforming a host plant by (V). (V) is also useful for providing germ-resistance to a host plant, which involves transforming a host plant by (V) (claimed). (I) is useful for providing defense response against microbe e.g. Phytophthora infestans causing late blight disease, in plants.
Novelty: New germ-responsive potato vetispiradiene synthase 3 promoter, capable of responding specifically to germ infection, useful for providing a defense response against a microbe causing late blight disease in plants
