Eucommia ulmoides, a dioecious tree species endemic to China, holds significant medicinal and economic value. This study delves into the genetic and molecular mechanisms underlying sex differentiation in E. ulmoides. Utilizing advanced genomic technologies, a high-quality chromosome-level genome assembly for both male and female E. ulmoides was achieved, revealing key insights into sex differentiation. Comparative transcriptome analyses identified differentially expressed genes (DEGs) between male and female individuals, highlighting the role of MADS-box transcription factors and specific genes such as EuAP3 and EuAG in sex determination. Additionally, molecular markers linked to sex determination were developed, facilitating early sex identification and improving breeding efficiency. The findings from this study provide a valuable genomic resource for further molecular biological studies and practical applications in the breeding and commercial production of E. ulmoides.
