Molecular and evolutionary analysis of a plant Y chromosome
Plants have evolved a great diversity of sex determination systems. Among these, the XY system, also found in mammals, is one of the most exciting since it gives the opportunity to compare the evolution of sex chromosomes in two different kingdoms. Whereas genetic and molecular mechanisms controlling sex determination in drosophila and mammals, have been well studied, very little is known about such processes in plants. White campion (Silene latifolia) is an example of plant with X and Y chromosomes. What is the origin of the X and Y chromosomes? How did they evolve from a pair of autosomes? In our laboratory, we have isolated the first active genes located on a plant Y chromosome. We are using them as markers to trace the origin and evolution of sex chromosomes in the Silene genus.
