|a Nitrogen (N) is an essential nutrient for plant growth and development. Dioecious plants, especially perennial plants, are often faced with a shortage of N supply in nature. Poplar is one of the most important dioecious and perennials species. Due to the different ecological functions, female and male poplars adopt different adaptation strategies to N limitation. However, the regulation in epigenetic mechanism is poorly understood on sexes. Here, the integrative analysis of whole-genome bisulfite sequencing (WGBS), RNA sequencing, and plant physiological analysis on female and male Populus cathayana were performed. We found that N deficiency reprograms methylation in both sexes, and the CG and CHH methylation types played critical roles in female and male poplars, respectively. Induced by DNA methylation, N-deficient males had a stronger phenylpropanoid synthesis pathway and less anthocyanin accumulation than females, which not only strengthened the N cycle but also reduced the defense cost of males. In addition, compared with male poplars, females accumulated more starch to expend excess energy under N limited condition. Additionally, DNA methylation also mediated hormone signalling involved in anthocyanin synthesis and starch metabolism. Therefore, our study reveals new molecular evidences that male poplars are more tolerant to N deficiency than females, which provides a reference for ecological adaptability of forest trees
