sex determination in dioecious plants

[Dominique Schaller]

Hi,
a considerable amount of work has been done on sex determination in
animals  ( drosophila, caenorhabditis, vertebrate) and in yeast, but I
have never seen something published on the genetics or the molecular
mechanisms of sex determination in dioecious plants like yews, holly
or Actinidia.
I would be very interested if somebody could add any comments on this
topic.
Thanks in advance.
