There are three systems by which this happens fig. Cloning and expression of genes involved in conidiation and surface properties of Penicillium camemberti grown in liquid and solid cultures. Finally, we highlight gaps in our knowledge so far and propose some specific areas within the field that we recommend a greater focus on in the future, including the role of ecology in sex chromosome evolution and new multilocus models of sex chromosome divergence.

Plant sex chromosomes can be vastly different from those of the few historical animal model organisms from which most of our understanding of sex chromosome evolution is derived. All mature seeds from the fruit were planted in a Metromix Scotts-Sierra Horticultural Products, Marysville, OH :greenhouse soil mixture, and transplanted to 1L pots at the 4-leaf stage.

The same deleterious interactions may result in developmental failure before zygote formation in XY fruit, as they are likely to disproportionately affect tissues with high metabolic needs.

Origin of amniote sex chromosomes: an ancestral super-sex chromosome or common requirements? Andrew H. Example progression of XY sex chromosome evolution. Recombining regions are indicated with crossed double-ended arrows.

Acknowledgments We thank two anonymous referees, Susanne Renner and editor Kateryna Makova for their helpful comments, Jeff Lemaitre for helpful discussions about generation times, and Benjamin Herran for preparing a previous version of figure 3. Growing these seeds and determining their sex-chromosome genotype allowed us to determine whether an X chromosome is required for normal ovule development.

Genetic mapping of sex determination in a wild strawberry, Fragaria virginiana , reveals earliest form of sex chromosome. Yehoshua Saranga, Andrew H. The funder had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
