等电聚焦分析表明，配子体自交不亲和的日本梨品种的S基因型与其花柱RNA酶同工型相关。在自交亲和突变体中，与S等位基因相关的条带比原始品种中的强度低得多。这些结果表明，RNase同工型可能是S基因在花柱中的产物。
Isoelectric focusing revealed thatS-genotypes of Japanese pear varieties with gametophytic self-incompatibility were correlated with the isoforms of their stylar RNases. In a self-compatible mutant, theS-allele-related band was much less intense than in the original variety. These observations suggest that the RNase isoforms may be the stylar products ofS-genes.
