Question

Quizplus · Accepted Answer

Self-incompatibility in plants involves the recognition and rejection of self-pollen by the stigma. This is often mediated by the expression of ribonucleases (RNAases) in the stigma cells that degrade RNA in the self-pollen, leading to inhibition of fertilization. Therefore, looking for RNAase activity in the stigma cells would be a good way to characterize self-incompatibility in the plant. Choices B, C, D, and E are not directly related to self-incompatibility.
