Recurrent sex chromosome turnover mediated by distinct ARR17 and PISTILLATA duplications in willows

YWYuan WangZXZhi‐Qing XueRZRengang Zhang

Key Points

  • The aim is to explore how ARR17 and PISTILLATA gene duplications contribute to sex chromosome turnover in Salix species.
  • Analysis of genetic structures in 15ZW clade I species
  • Investigation of recombination patterns in pericentromeric regions
  • Comparative genomic assessments between species
  • Distinct duplications of ARR17 and PISTILLATA were identified in multiple Salix species.
  • Pericentromeric regions demonstrated rare recombination events, facilitating sex chromosome changes.
  • Findings indicate that these duplications influence evolutionary pathways in willows.

Abstract

The turnover events involving intact ARR17 and partial PI duplications in the 15ZW clade I species involve pericentromeric regions that recombine rarely, making changes possible in these Salix species that would be unlikely in other genome regions.
