The Sex Life of Plants
You have successfully signed up! Sexual reproduction in animals and plants share common elements, but little was known about how the sex of plants is determined until University of Tasmania researchers discovered a gene responsible. The research highlights the extraordinary effect that a plant hormone - abcisic acid, or ABA - which originally evolved to control sex, has had on land plant evolution and ecology over the past million years. Since the dawn of land plants, ABA has played a critical role in regulating plant responses to water availability.






USC College biologist Magnus Nordborg leads two studies that revise our understanding of sex evolution and genetic heritage. The ability of plants to self-pollinate — a big factor in the spread of weeds — is much older than previously thought in one widely studied species, leading biologists say. Self-pollination, or selfing, confers a major advantage to weedy species. A selfing plant can invade new territory by itself and colonize it alone.
