Abstract:

Sweetpotato (Ipomoea batatas (L.) Lam.) has the characteristics of high yield, strong adaptability, high proliferation rate and high nutritional value, and is an important root crop in the world. With the continuous development of biotechnology, the genetic improvement of sweetpotato by genetic engineering technology has become a current topic in China and abroad. In this article, we provide an overview and analysis of the genetic transformation methods and influencing factors of sweetpotato, such as agrobacterium-mediated method, electric shock method and gene gun method, and review the latest research progress in the genetic transformation of sweetpotato, including improvement in abiotic stress resistance, antibiotic stress, herbicide resistance, nutritional quality and root development. We also discuss and look forward to the application prospect of genetic engineering in sweetpotato genetic improvement and related biosafety issues, in order to provide reference for the future research on genetic engineering improvement of sweetpotato.
