Transcriptomics and metabolomics datasets of Paris polyphylla var. yunnanensis with different growth years

Paris polyphylla var. yunnanensis is a widely cultivated rhizomatous perennial woody plant known for producing the highly valued steroidal saponins. Steroidal saponins serve as the primary active component and exhibit a variety of pharmacological effects. However, the accumulation of secondary metabolites and the related functional genes involved in plant biosynthesis varies across different developmental stages. In this study, we collected samples of P. polyphylla var. yunnanensis aged 3-8 years for metabolome and transcriptome sequencing analysis. A total of 1510 metabolites and 270.65 Gb of clean data were identified from these samples. This research aims to provide a theoretical foundation for understanding the internal mechanisms governing the accumulation of secondary metabolites and the formation of quality in P. polyphylla var. yunnanensis, thereby establishing a basis for its efficient cultivation and increased saponin yield.
