C768Y a C-to-T missense mutation in the first exon, the naturally occuring mutant rdr6-11 of RDR6 shows simultaneously enhanced SI and stigma exsertion, without associated increases in SRK transcript levels, phenotype, overview. The mutant exhibits stochastic stigma exsertion, and the S-locus receptor kinase, SRK, gene further enhances pistil elongation and stigma exsertion in this mutant background, a process that requires SRK catalytic activity and correlates with SRK transcript levels. rdr6-11 mutant plants are fertile and produce full siliques. By contrast, self-pollination of rdr6-11::Sb stigmas results in very low numbers of seeds per silique, indicating that mutant stigmas maintain SI into late stages of flower development even upon prolonged pollen-stigma contact Arabidopsis thaliana
