Cloning a lysine rich protein gene from potato cultivar Thuong Tin and construction of the expression vector

Lysine is one of the limiting essential amino acids because it is not synthesized in the body of animals and human. They must obtain lysine from their diet. Recent results of gene transfer research showed the possibility of overexpression of genes encoding natural lysine-rich proteins in crops such as rice and corn, to improve protein quality by increasing the lysine content.
