Lycium chinense Mill. (L. chinense) is a solanaceous defoliated shrub that grows in China and other parts of Asia. The fruit of L. chinense, known as Fructus lycii or Chinese wolfberry, has been regarded as an ingredient in the traditional herbal medicine with functions of nourishing the kidney and the liver (Amagase and Farnsworth, 2011). Valuable components of L. chinense are not limited to its high level of carotenoids, but include the polysaccharides and small molecules such as antioxidant enzymes and betaine. But until now, studies on the role of cAPX gene from L. chinense have not been reported.
