|a Lectins are proteins of non-immune origin that specifically interact with carbohydrates, known to play important roles in the defense system of plants. In this study, in order to study the function of a new soybean lectin (SBL), the corresponding encoding gene lec-s was introduced into tobacco plants via Agrobacterium-mediated transformation. Southern blot analyses had revealed that the lec-s gene was stable integrated into the chromosome of the tobacco. The results of the reverse transcription polymerase chain reaction (RT-PCR) also indicated that the lec-s gene in the transgenic tobacco plants could be expressed under the control of the constitutive CaMV35S promoter. Evaluation agronomic of the performance had showed that the transgenic plants could resist to the infection of Phytophthora nicotianae. Insect bioassays using detached leaves from transgenic tobacco plants demonstrated that the ectopically expressed SBL significantly (P.0.05) reduced the weight gain of larvae of the beet armyworm (Spodoptera exigua). Further on, the lectins retarded the development of the larvae and their metamorphosis. These findings suggest that soybean lectins have potential as a protective agent against pathogens and insect pests through a transgenic approach
