How a gene tells plant to reject its own pollen

from a type-B kale plant, but in this experiment, the pollen carrying the transferred SCR gene was recognized by the type-A stigma as being type-A. Thus, because of the self-incompatibility mechanism in the plant, the pollen was rejected.

The Science paper, "The Male Determinant of Self-Incompatibility in Brassica," was authored by the Nasrallahs and Schopfer. Research funding was provided by the National Science Foundation, the National Institutes of Health and the U.S. Department of Agriculture.
