Long-term seed dormancy of Paris polyphylla var. yunnanensis limits its large-scale artificial cultivation. It is crucial to understand the regulatory genes involving in dormancy release for artificial cultivation in this species. In this study, seed dormancy of Paris polyphylla var. yunnanensis was effectively released by warm stratification (20°C) for 90 days. The freshly harvested seeds (dormant) and stratified seeds (non-dormant) were used to sequence, and approximately 147 million clean reads and 28,083 annotated unigenes were detected. In which, a total of 10,937 differentially expressed genes (DEGs) were identified between dormant and non-dormant seeds. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) classification revealed that the majority unigenes involved in signaling transduction and carbohydrate metabolism. Of them, the signaling transduction-related DEGs were mainly hormones-, reactive oxygen species (ROS)-, and transcription factor (TF)-related genes. The largest number of signaling transduction-related DEGs were auxin-responsive genes (SAUR, AUX/IAA, and ARF) and AP2-like ethylene-responsive transcription factor (ERF/AP2). Moreover, at least 29 DEGs such as α-amylase (AMY), β-glucosidase (Bglb/Bglu/Bglx), and endoglucanase (Glu) were identified involving in carbohydrate metabolism. These identified genes provide a valuable resource to investigate the molecular basis of dormancy release in Paris polyphylla var. yunnanensis.
