From homomorphy to heteromorphy: stratified trajectories of sex chromosome expansion in Silene latifolia

Year: 2025

Type: article

Abstract: A recent analysis of the Silene latifolia Y chromosome has demonstrated that suppressed recombination drives its expansion into evolutionary strata and accelerates functional degeneration through transposable element accumulation, DNA hypermethylation, and gene silencing. This finding reinforces the importance of structural dynamics in plant sex chromosome evolution and drives us to consider the conserved yet flexible trajectories of degeneration across kingdoms, concluding that S. latifolia provides a pivotal model for elucidating both canonical and divergent mechanisms of sex chromosome evolution.
