Description

<p>Genetic improvement of soybean seed traits is important for developing new varieties that meet the demand for soybean as a food, forage crop, and industrial products. A large number of soybean genome sequences are currently publicly available. This genome sequence information provides a significant opportunity to design genomic approaches to improve soybean traits. Genome editing represents a major advancement in biotechnology. The production of soybean mutants through genome editing is commonly achieved with either an Agrobacterium-mediated or biolistic transformation platform, which have been optimized for various soybean genotypes. Currently, the clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated endonuclease 9 (Cas9) system, which represents a major advance in genome editing, is used to improve soybean traits, such as fatty acid composition, protein content and composition, flavor, digestibility, size, and seed-coat color. In this review, we summarize the recent advances in the improvement of soybean seed traits through genome editing. We also discuss the characteristics of genome editing using the CRISPR/Cas9 system with transformation platforms.</p>
