Gametophytic self-incompatibility in Rosaceae fruit trees
Acta Scientiarum Polonorum: Hortorum Cultus, 2019 Rosaceae fruit trees are characterized by gametophytic self-incompatibility, with their production typically requiring artificial pollination or pollination tree is required in production.

Research Progress on Calcium Ion in Gametophytic Self-Incompatibility
Journal of Horticultural Research, 2022 Calcium ions are involved in plant self-incompatibility response as important signaling substances in cells. In the sporophytic self-incompatibility response, Ca2+ enters the stigma papilla cells and plays a key role in inhibiting incompatible pollen ...

BMC Evolutionary Biology, 2010 Background Within Rosaceae, the RNase based gametophytic self-incompatibility (GSI) system has been studied at the molecular level in Maloideae and Prunus species that have been diverging for, at least, 32 million years.

Characterisation of the Gillenia S-locus provides insight into evolution of the nonself-recognition self-incompatibility system in apple [PDF]
Scientific ReportsSelf-incompatibility (SI) in plants has evolved independently multiple times and S-RNase-based gametophytic self-incompatibility (GSI) is most common.

Int J Mol Sci, 2019 Self-incompatibility (SI) is a complex process, one out of several mechanisms that prevent plants from self-fertilizing to maintain and increase the genetic variability. This process leads to the rejection of the male gametophyte and requires the co-participation of numerous molecules.

Agronomy, 2022 The cultivated almond displays a gametophytic self-incompatibility system, which avoids self-fertilization, and it is controlled by a multi-allelic locus (S-locus) containing two genes specifically expressed in pistil (S-RNase) and pollen (SFB).

Plant GenomeAbstract Gametophytic self‐incompatibility (GSI) is a reproductive strategy to prevent inbreeding and promote outcrossing. Studies to understand molecular and evolutionary aspects of the self‐compatibility (SC)/self‐incompatibility (SI) system in the Solanaceae have been conducted using several genera including Petunia Juss., Nicotiana L., and Solanum ...

Gametophytic Self-Incompatibility Systems [PDF]
The Plant Cell, 1993 is one of the mechanisms that have evolved to encourage outbreeding in flowering plants and is defined as “the inability of a fertile hermaphrodite seed plant to produce zygotes after self-pollination” (de Nettancourt, 1977). The effectiveness of SI in promoting outbreeding is believed to be one of the most important factors that ensured the evolu ...
