Cover illustration:   Catkins of poplar and willow are arranged as XY and ZW, symbolizing the repeated turnover of sex chromosome systems in Salicaceae. Poplar leaves and willow shoots distinguish the two sister genera, while a pale DNA strand links the four chromosomal forms, representing their shared evolutionary history. In this issue, Wang et al. (pp. 437–453) compared male and female catkin and leaf transcriptomes across eight dioecious Salicaceae species. Their study reveals extensive turnover of sex-biased expression in reproductive tissues, limited conservation of core sex-biased genes, and early but incomplete dosage compensation associated with young, dynamic sex chromosomes. Illustrated by Tao Ma, Deyan Wang, and Xiaogang Dai.
