甘蔗抗虫转基因研究进展
Research progress on insect resistant transgenic sugarcane
摘要
Abstract
Sugarcane is the world's most important sugar producing crop. However, during recent years, sugarcane quality and yield were heavily influenced by serious insect pest attack. In order to combat this insect pest attack, insect resistant transgenic sugarcane breeding, an effective insect pest prevention method, was adopted by many sugarcane breeding faculties. In recent years, larger sugarcane producing faculties in the United States, Australia, Brazil, South Africa, Cuba, Thailand, India, Singapore, and China began to carry out insect resistant transgenic sugarcane breeding researches; the researches mainly concentrated on screening transgenic sugarcane materials with iff gene, GNA gene, and PI gene. Through these already conducted researches, a batch of transgenic sugarcane materials was obtained viz., CrylA (b)transgenic plants anti stem borer and Chilo infuscatellus, GNA transgenic sugarcane plants anti aphid, PI transgenic sugarcane plants anti white moth, GNA and Pi II transgenic sugarcane clones G87 and UP87 inhibiting grub larval growth, and 600 accessions of crylC* transgenic sugarcane clones. On the other hand, the physiology, insect resistance, and agronomic traits of Bt transgenic sugarcane plants were also researched. Since researches on insect-resistant transgenic sugarcane began only recently, insect-resistant gene sources and knowledge on the intellectual property protection rights were restricted, resuting in relatively slow research progress, so excellent insect-resistant transgenic sugarcane varieties have not yet been bred. In the future, various factors affecting gene expression, such as the integration, genetic expression characteristics, methylation modification of exogenous gene in generation of transgenic sugarcane clones, etc., should be furtherly studied in order to enhance the inheritance and expression stability of exogenous gene in sugarcane clones. Moreover, the transgenic sugarcane resistance mechanism was also comprehensively analyzed in order to select stable hereditary and excellent resistance sugarcane varieties to provide theoretical bas and germplasm resources for breeding sugarcane varieties.关键词
