DOI: 10.1002/ajb2.1441
Abstract: PREMISE Newly formed polyploids face significant obstacles to persistence and population establishment because of fitness costs of intercytotype mating. Selfing provides the opportunity to escape mate limitation, enabling production of new individuals and increasing the… read more here.

DOI: 10.1007/s00497-017-0300-7
Abstract: Late-acting self-incompatibility (LSI) has been defined as a genetically controlled self-sterility mechanism that prevents seed set by selfing, despite normal pollen tube growth and ovule penetration in self-pollinated pistils. In species of the Bignoniaceae with… read more here.

DOI: 10.1016/j.scienta.2018.05.050
Abstract: Abstract Apples (Malus ×domestica Borkh.) are one of the largest economically significant fruit crop worldwide. Due to the self-incompatibility of most Malus cultivars, the apple industry relies on insect pollinators to aid in cross-pollination to… read more here.

Abstract: Abstract Self-incompatibility in European red raspberry (Rubus idaeus L.) is less studied compared to other horticulturally relevant rosaceous crops, although cultivars of this species show differences in self-fertility. In this study, we genotyped progenies of… read more here.

DOI: 10.1038/s41438-021-00634-8
Abstract: Self-incompatibility (SI) substantially restricts the yield and quality of citrus. Therefore, breeding and analyzing self-compatible germplasm is of great theoretical and practical significance for citrus. Here, we focus on the mechanism of a self-compatibility mutation… read more here.

DOI: 10.1093/plphys/kiac026
Abstract: Successful reproduction in the Brassicaceae is mediated by a complex series of interactions between the pollen and the pistil, and some species have an additional layer of regulation with the self-incompatibility trait. While the initial… read more here.
