description <p>White campion (<em>Silene latifolia</em>, Caryophyllaceae) is a classical model species for studies of sex determination and sex chromosome evolution in dioecious plants. Deletion mapping in this species revealed the presence of two Y-linked sex determining genes&mdash;the stamen promoting factor (<em>SPF</em>) gene and a gynoecium suppressing factor (<em>GSF</em>), which inspired the development of the classic &lsquo;two genes&rsquo; model for dioecy evolution. We recently identified a Y-linked&nbsp;<em>GSFY</em>&nbsp;gene that encodes a&nbsp;<em>CLAVATA3</em>&nbsp;homolog and causes gynoecium suppression in&nbsp;<em>S. latifolia</em>&nbsp;<em>via</em>&nbsp;WUSCHEL-CLAVATA feedback loop. Interestingly, the&nbsp;<em>WUSCHEL</em>&nbsp;homolog in&nbsp;<em>S. latifolia</em>&nbsp;(<em>SlWUS1</em>) is also sex-linked and both&nbsp;<em>GSFY</em>&nbsp;and&nbsp;<em>SlWUS1</em>&nbsp;are located in the oldest part of the sex chromosomes, suggesting that selection to prevent recombination between these genes may have contributed to the origination of sex chromosomes in this species. The&nbsp;<em>WUS</em>-<em>CLV3</em>&nbsp;pathway is also involved in the sexual differentiation of gynoecium development in kiwifruits and melon, indicating that this pathway plays central role in gynoecium suppression in dioecious and monoecious plants.</p>
