  • Method for conducting high-throughput and directed mutagenesis for sugarcane resistance to glyphosate by plasma
    Patent number: 11516979
    Abstract: The present invention relates to a method for conducting high-throughput and directed mutagenesis for sugarcane resistance to glyphosate by plasma. The method is as follows: sugarcane embryonic calli are irradiated by a plasma instrument under a sterile condition for mutagenesis, wherein the mutagenesis power is 140˜200 W, the discharging distance is 35˜45 mm, the mutagenesis time is 110˜140 s and the protective gas is nitrogen; buffering culture, moderate/high concentration of glyphosate stress screening, differentiation into seedlings, glyphosate stress screening of bottle seedlings and stress screening via spraying glyphosate on the leave surfaces of potted plants are conducted for the treated calli. The present invention has the advantages of safe operation, simplicity, practicability, high handling capacity, low contamination, and due to implementation of directed stress screening, high screening efficiency, decreased subsequent screening workload and visual identification of resistant mutant strains.
