Biologists discover gene behind 'plant sex mystery'
Date:10/22/2008

cks promotes the production of a twin sperm cell cargo in each pollen grain and thus ensures successful reproduction in flowering plants.

"This discovery is a significant step forward in uncovering the mysteries of flowering plant reproduction. This new knowledge will be useful in understanding the evolutionary origins of flowering plant reproduction and may be used by plant breeders to control crossing behaviour in crop plants.

"In the future such information may become increasingly important as we strive to breed superior crops that maintain yield in a changing climate. Given that flowering plants dominate the vegetation of our planet and that we are bound to them for our survival, it is heartening that we are one step closer to understanding their reproductive secrets."

Researchers at the University of Leicester are continuing their investigation into plant reproduction. Further research underway in Professor Twell's laboratory is already beginning to reveal the answers to secrets about how the pair of sperm cells produced within each pollen grain aquires the ability to fertilize.
