title: Plant evolution: modern sex chromosomes.
abstract: The first detailed map has been produced of a plant chromosome carrying sex-determining genes. The new data show that, in papaya, these genes lie in a quite extensive non-recombining region. This region is nevertheless a small part of the papaya genome compared with other male-specific genome regions, such as mammalian Y chromosomes.
