passages.text: Here we show that a single form of SP11 of the S8 haplotype ( S8 - SP11 ) stabilized with four intramolecular disulphide bonds specifically binds the stigma membrane of the S8 haplotype to induce autophosphorylation of SRK8 , and that SRK8 and SLG8 together form a high - affinity receptor complex for S8 - SP11 on the stigma membrane .
