摘　　要：Dear Editor,In trans-specific S-haplotypes,crossover recombination at the S-locus,which controls self-incompatibility,has been thought to be highly suppressed.Here,we discovered a previously unreported super S haplotype,derived from a rare inter-haplotypic recombination event,that contained two complete suites of functional S-RNase and SLF genes and could break the SI response in trifoliate orange through“self-recognition”within the same pollen.
