Exogenous Glutathione enhances tolerance of the potato (Solanum tuberosum L.) to cadmium stress by regulating the biosynthesis of phenylpropanoid and the signal transduction of plant hormones

Abstract

Highlights 1. Glutathione affected the synthesis of phenylpropanoid in the potato. 2. Glutathione affected the levels of plant hormone and the expression of related genes in potato. 3. Glutathione enhanced the tolerance of potato to cadmium stress. 4. Some genes play an important role in potato response to cadmium stress.
