Chinese researchers have created excellent quality of high-yielding new strains of rape

Oil Crop Research Institute rape molecular improvement theory and technological innovation team using CRISPR / Cas9 gene editing system to knock out the canola BnaMAX1s gene, creating a new excellent strain quality, for rape high-yielding new varieties to provide excellent breeding resources, oil menu plant production is expected to increase by about 30%. The latest research was published online in the internationally renowned journal Journal of Plant Biotechnology.
, the author of the paper and a researcher at the Oil Institute, said that the high plant height and number of branches of rape are the key components of its strain type, and also directly affect the yield. Reducing plant height and increasing the number of branches can make the plant maintain a certain biomass, which is one of the effective ways to achieve high rapeseed yield, but there is no available breeding resources. Therefore, improving the structure of rape strains is a major challenge in rape breeding.Zheng Ming, the first author of
's paper and an assistant researcher at the Oil Institute, said that by designing a specific target using crispr/Cas9 gene editing system, they simultaneously edited two simultaneous copies of the BnaMAX1 gene in rape in spring rape, and obtained an editing plant with a esoteric esoteric form of half-dwarf, multi-branch and multi-angled fruit. Compared with the control, the editing plant was higher and lower, the number of branches increased at a time, the number of single horn fruit increased, and the yield of a single plant increased by about 30%.
that the research has been supported by projects such as the National Natural Science Foundation of China, the National Key Research and development program,
Agricultural science and technology innovation project.
