- Abstract
Four highly inducible genes of poplar trees, PtdKTI5, PtdWIN4, PtdPOPi from hybrid poplar (Populus trichocarpa x P. deltoides) and PtKTI2 from trembling aspen (Populus tremuloides Michx.) have been indi-vidually transformed into Arabidopsis thaliana for overexpression. High transcriptional level of each trans-gene in transgenic Arabidopsis lines was confirmed by RT-PCR analysis. The development, body weight and survivorship of cotton bollworm (Helicoverpa armigera) fed on four types of transgenic Arabidopis plants were evaluated in the laboratory. Our data indicated that these four Populus defense-related genes exhibited various degree of insectital activity on larval and postlarval development of cotton bollworm and may be uti-lized for herbivore resistance improvement in plant genetic engineering.
