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.

Rapid detection of RNase‐based self‐incompatibility in Lysimachia monelli (Primulaceae)
Sign Up to like & getrecommendations! Published in 2025 at "American Journal of Botany"
DOI: 10.1002/ajb2.16449
Abstract: Abstract Premise Primroses famously employ a system that simultaneously expresses distyly and filters out self‐pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self‐incompatibility (SI), but involving a system with… read more here.

DOI: 10.1007/s00299-025-03546-2
Abstract: Cytological and molecular investigations in chicory revealed crucial aspects related to female gametophyte development, pollen‒stigma interactions, and self-incompatibility responses. The Asteraceae family, one of the largest of angiosperms, comprises approximately 24,000 species and exhibits considerable… read more here.

Evidence for post-zygotic self-incompatibility in Handroanthus impetiginosus (Bignoniaceae)

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.

Decay of self-incompatibility within a lifespan in Physalis acutifolia (Solanaceae)

DOI: 10.1007/s00497-024-00517-7
Abstract: Self-incompatibility decays with age in plants of Physalis acutifolia, and plants that have transitioned to selfing produce fewer seeds but with comparable viability. Self-compatibility in this system is closely related to flower size, which is… 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.

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.

Abstract: Self-incompatibility (SI) in plants has evolved independently multiple times and S-RNase-based gametophytic self-incompatibility (GSI) is most common. The Rosaceae family possesses both self-recognition (Prunus) and nonself-recognition (Malus) GSI systems, and the latter is widespread in… read more here.
