Abstract High yield, high quality, stable yield, adaptability to growth period, and modern mechanization are the basic requirements for crops in the 21st century. Soybean oleic acid is a natural unsaturated fatty acid with strong antioxidant properties and stability. Known as a safe fatty acid, it has the ability to successfully prevent cardiovascular and cerebrovascular disorders. Improving the fatty acid composition of soybean seeds, can not only speed up the breeding process of high-quality high-oil and high-oleic soybeans, but also have important significance in human health, and provide the possibility for the development of soybean oil as a new energy source.… More >

Abstract The fatty acid dehydrogenase gene plays an important role in regulating the oleic acid content in soybean. Genome-wide association study screened out soybean oleic acid related gene Gm15G117700. A fragment size of 693bp was obtained by PCR amplification of the gene and, it was connected by seamless cloning technology to the pMD18T cloning vector. Based on the gene sequence cloned, bioinformatic analysis of gene protein was performed. The overexpression vector of Gm15G117700 and the CRISPR/Cas9 gene editing vector were constructed. The positive plants were obtained by Agrobacterium-mediated transformation of soybean cotyledon nodes and T₂ plants were identified by conventional PCR,… More >
