Few cases of replacements by new factors have been documented in dioecious plants, but are suspected in Salix, in which both XY and ZW systems occur, with sex-linked regions (SLRs) of different species on various chromosomes. The male-determining genes in XY species’ SLRs are partial duplicates of autosomal ARR17-like genes and regulate the expression of downstream genes involved in stamen development by producing small RNAs that suppress the expression of intact copies.},
