Big differences found in male and female jojoba plant sex genes

Hot desert sex has resulted in major genetic differences between male and female jojoba plants — one of only 6 percent of plants that require a male and female plant to reproduce. New research suggests male and female jojoba plants have diverged so much, that the jojoba plant has more novel sex genes than any other known living organism. The discovery may help researchers develop a DNA test to identify male and female jojoba plants, which cannot be distinguished from each other as seedlings – and shed light on how plants adapt to environmental stress.
