Self-awareness out the foundation of scientific evidence that plants could be considered as self-aware organisms. The SI (Self-incompatibility) mechanism in plants is unique in the sense that awareness of self derives from the capacity to recognise self, rather than non-self. The SI mechanism function depends primarily on the interaction between genes "S"-locus receptor protein kinase (SRK) and "S"-locus cysteine-rich protein gene ("SCR)." In cases of self-pollination, SRK and SCR bind to activate SKR, Inhibiting pollen from fertilizing. In cases of cross-pollination, SRK and SCR do not bind and therefor SRK is not activated, causing the pollen to fertilise. In simple terms,
