Summary:
Over a century ago, scientists discovered that some plants don't permit fertilization by their own pollen. And for the past quarter-century, scientists have known that cellular communication exists between the female stigma and the male gamete, or pollen, it receives. But no one knew how the stigma could tell the difference between the plant's own pollen and that from other plants. Now, Cornell University researchers have unlocked this basic, long-standing botanical mystery in a report in the Nov. 26 edition of the journal Science.
