Abstract:

Stilbenes have been recognized for their beneficial physiological effects on human health. Stilbene synthase (STS) is the key enzyme of resveratrol biosynthesis and has been studied in numerous plants. Here, four MaSTS genes were isolated and identified in mulberry (Morus atropurpurea Roxb.). The expression levels of MaSTS genes and the accumulation of trans-resveratrol, trans-oxyresveratrol, and trans-mulberroside A were investigated in different plant organs. A novel coexpression system that harbored 4-coumarate:CoA ligase gene (Ma4CL) and MaSTS was established. Stress tests suggested that MaSTS genes participate in responses to salicylic acid, abscisic acid, wounding, and NaCl stresses. Additionally, overexpressed MaSTS in transgenic tobacco elevated the trans-resveratrol level and increased tolerance to drought and salinity stresses. These results revealed the major MaSTS gene, and we evaluated its function in mulberry, laying the foundation for future research on stilbene metabolic pathways in mulberry.
