Gametophytic self-incompatibility re-examined: a reply [PDF]

Heredity, 1985
In principle, as has long been known, there are two ways by which the stigmas or styles of the flowers of self-incompatible species could discriminate between incompatible and compatible pollen, for either the growth of the former would be inhibited (the oppositional hypothesis) or that of the latter stimulated (the complementary hypothesis).

Self-incompatibility in passionfruit: evidence of gametophytic-sporophytic control

Theoretical and Applied Genetics, 2003
Self-incompatibility in passionfruit was studied in families originated from crosses among plants that presented differences in reciprocal crosses. The three families, obtained by crossing S(3) plants, exhibited one incompatible group; no reciprocal differences were observed. The phenotype of the families was the same as the parent plants, S(3).

Molecular S-genotyping of sweet cherry (Prunus avium L.) genetic resources

Horticultural Science, 2019
Sweet cherries are self-incompatible, which is determined by a gametophytic self-incompatibility system (GSI). The self-incompatibility is controlled by a multi-allelic S-locus.

HT-B and S-RNase CRISPR-Cas9 double knockouts show enhanced self-fertility in diploid Solanum tuberosum

Frontiers in Plant Science, 2023
The Gametophytic Self-Incompatibility (GSI) system in diploid potato (Solanum tuberosum L.) poses a substantial barrier in diploid potato breeding by hindering the generation of inbred lines.

Different Flowering Strategies Ensure Reproductive Success in Two Coexisting Self-Incompatible Orchids. [PDF]

Ecol Evol
This study compares the reproductive strategies of two self‐incompatible orchids, Pholidota articulata (mass‐flowering) and Coelogyne prolifera (steady‐state flowering). Despite differences in pollinator visitation and pollinia transfer efficiency—higher in P. articulata—both species achieved similar natural fruit set rates over 3 years.

Disentangling the components of pollen limitation in a widespread herb with gametophytic self‐incompatibility

American Journal of Botany, 2023
AbstractPremiseSeed production is frequently limited by the receipt of insufficient or low‐quality pollen, collectively termed “pollen limitation” (PL). In taxa with gametophytic self‐incompatibility (GSI), incompatible pollen can germinate on stigmas but pollen tubes are arrested in styles.

Association of T2/S-RNase With Self-Incompatibility of Japanese Citrus Accessions Examined by Transcriptomic, Phylogenetic, and Genetic Approaches

Frontiers in Plant Science, 2021
Several citrus varieties show gametophytic self-incompatibility (GSI), which can contribute to seedless fruit production in several cultivars. This study investigated the genes regulating this trait through RNA-seq performed using styles collected from ...

Transcriptome Analysis of the Late-Acting Self-Incompatibility Associated with RNase T2 Family in Camellia oleifera

Plants, 2023
The Camellia oil tree (Camellia oleifera Abel.) is an important nonwood forest species in China, and the majority of its cultivars are late-acting self-incompatibility (LSI) types.

EVOLUTION OF GAMETOPHYTIC AND SPOROPHYTIC SYSTEMS OF SELF-INCOMPATIBILITY IN ANGIOSPERMS [PDF]

Evolution, 1960
Self-incompatibility has been found in at least 78 angiosperm families and occurs in every major phylogenetic line (East, 1940; Fryxell, 1957; Brewbaker, 1957). It has even been discovered in at least three gymnosperm species (Pinus sylvestrisGustaffson, cited by Bateman, 1952; Larix laricina, Pseudotsuga taxifoliaFryxell, 1957), and one pteridophyte ...

S-RNase–mediated Gametophytic Self-Incompatibility is Ancestral in Eudicots [PDF]

Molecular Biology and Evolution, 2002
The evolutionary relationship between self-incompatibility systems in different families of flowering plants has long been a topic of interest. Physiological differences in the mode of gene action and the enormous sequence differences between genes with different modes of action suggest that many instances of self-incompatibility have arisen ...
