Self-compatibility in loquat (Eriobotrya japonica Lindl.) is possibly due to S6-RNase mutation.

Highlights: [•] S6ins-RNase was cloned from the self-compatible loquat cultivars. [•] Four S6-SFBs were cloned from homozygote S6 loquat seedlings. [•] A 24-nucleotide insertion was identified within S6ins-RNase open reading frame. [•] No mutation was observed in the S6-SFBs. [•] The mutation in S6ins-RNase was found to be responsible for SC in these cultivars. [ABSTRACT FROM AUTHOR]
