Studying on the strictly self-compatibility mechanism of 'Liuyefeitao' peach (Prunus persica L.).

ABSTRACT: Peach (Prunus persica L.) generally exhibits self-pollination, however, they can also be pollinated by other varieties of pollen. Here we found two varieties that are different from other peaches: 'Daifei' and 'Liuyefeitao'. 'Daifei' produces less pollen, which needs artificial pollination, honeybee pollination, and the fruit setting depends on other varieties of peach pollen. 'Liuyefeitao' exhibits strictly self-pollination, hence pollen from other species is rejected. To explore the mechanism of this phenomenon, we performed a high-throughput sequencing of the stigma (including style) of 'Daifei' and 'Liuyefeitao' to explain the rejection mechanism of other varieties of pollen of 'Liuyefeitao' peach. In our study, we found one S gene, and lots of non-S-locus factors such as: F-box protei
