Transgenic plant of the species Solanum tuberosum with resistance to Phytophthora

The present invention concerns a transgenic plant of the species Solanum tuberosum with a resistance to an oomycete of the genus Phytophthora， transgenic parts of such a plant， a method for its manufacture and to a composition for external application to plants. On the one hand， nucleotide sequences in accordance with SEQ ID NOS: 1-43 are provided from Phytophthora in a host plant-induced gene silencing strategy in potato plants; on the other hand， a fungicide for plant treatment is provided.

本发明涉及一种对疫霉属（Phytophthora）卵菌具有抗性的马铃薯（Solanum tuberosum）转基因植株、此类转基因植株的转基因部分、其制备方法以及一种用于植物外部施用的组合物。一方面，本发明提供了源自疫霉属（Phytophthora）、符合SEQ ID NO:1至43的核苷酸序列，将其应用于马铃薯植株以实施宿主诱导基因沉默（host plant-induced gene silencing）策略；另一方面，本发明还提供了一种用于植物病害防治的杀菌剂。
