Description

Type-2 SI is the sporophytic Brassicaceae-type SI, controlled by a male S-locus cysteine-rich (SCR) protein/S-locus protein 11 and a female S-locus receptor kinase (SRK). Pollen S₁-SCR can specifically recognize its cognate S₁-SRK after pollination, triggering several signaling cascades mediated by phosphorylation and ubiquitin-proteasome system, thus leading to self-pollen rejection.
