Incapable of self-fertilization.

self′-in′com·pat′i·bil′i·ty n.

Mate availability in small populations of plant species with homomorphic sporophytic self-incompatibility.
In this project, we will focus on the sporophytic self-incompatibility system in outcrossing Arabidopsis species, a model biological system in which two distinct co-evolutionary processes are becoming well-understood: 1) between the male and female reproductive proteins allowing self-pollen recognition and rejection and 2) between small non-coding RNAs and their target sites that jointly control the dominance/recessivity interactions between self-incompatibility alleles.

Arguably the best characterized of these systems is the self-incompatibility system in plants, which prevents fertilization from self-pollen (Kao and McCubbin, 1996; Schopfer et al.

Called gametophytic self-incompatibility, this plant system sabotages (male) pollen that's genetically similar to the female tissue of the plant.
