Abstract

The invention discloses sugarcane genome endogenous reference gene fructose-6-phosphate 2-kinase gene PCR (polymerase chain reaction) primer sequences and an amplification method. The primer sequences are composed of ScF2KP-F and ScF2KP-R. The PCR amplification method comprises a reaction system and amplification conditions. The invention provides a genome endogenous reference gene for PCR detection and species specific identification of transgenic sugarcane, and meanwhile, provides insurance for detection precision and result accuracy of the transgenic sugarcane.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a PCR primer sequence and an amplification method of an internal standard gene fructose-6-phosphate 2-kinase gene in sugarcane genome. Background technique [0002] Transgenic technology is becoming more and more mature, and the types of genetically modified sugarcane are becoming more and more diverse. At present, herbicide-resistant, insect-resistant, and disease-resistant genetically modified sugarcane has been field tested in 14 countries including the United States, Australia, India, and Brazil, creating conditions for the commercial cultivation of genetically modified sugarcane. In my country, sugarcane gene cloning and transgenic research only started in the mid-1990s. Although it started late, it has made rapid progress. The transgenic sugarcane that has been obtained includes insect-resistant genetically modified sugarcane, drought-resistant genetically m...
