| Abstract: | The oomycete pathogens produce important diseases in many plant species. To identify extensin genes expressed during the oomycete Phytophthora nicotianae-Nicotiana megalosiphon interaction, we used the SuperSAGE technology. Using this approach, we detected a N. megalosiphon extensin gene (NmEXT) triggered during the interaction. The extensin gene accumulation induced by the pathogen correlated with disease resistance in different Nicotiana species. Transient expression of NmEXT gene in susceptible Nicotiana tabacum enhanced the resistance to P. nicotianae. Our date indicated that NmEXT gene served a positive role in N. tabacum resistance against P. nicotianae. |
