The diversity of the pollen tube pathway in plants: toward an increasing control by the sporophyte [PDF]

, 2016
12 Pags.- 1 Fig.Plants, unlike animals, alternate multicellular diploid, and haploid generations in their life cycle. While this is widespread all along the plant kingdom, the size and autonomy of the diploid sporophyte and the haploid gametophyte ...

Detection of Self Incompatibility Genotypes in Prunus africana: Characterization, Evolution and Spatial Analysis. [PDF]

PLoS ONE, 2016
In flowering plants, self-incompatibility is an effective genetic mechanism that prevents self-fertilization. Most Prunus tree species exhibit a homomorphic gametophytic self-incompatibility (GSI) system, in which the pollen phenotype is encoded by its ...

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.

Molecular identification of S-alleles associated with self-incompatibility in apple (Malus spp.) genotypes

The Indian Journal of Agricultural Sciences, 2016
Gametophytic self-incompatibility, governed by the S-locus in apple (Malus spp.) plays a vital role for pollination and fruit set. The identification and cloning of RNases has enabled the use of molecular techniques to characterize Sgenotypes in apple ...

Evidence for rare recombination at the gametophytic self-incompatibility locus [PDF]

Heredity, 2003
The gametophytic self-incompatibility locus has been thought to be a nonrecombining genomic region. Inferences have been made, however, about the functional importance of different parts of the S-locus, based on differences in the levels of variability along the gene, and this is valid only if recombination occurs.

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 ...

Towards F1 Hybrid Seed Potato Breeding [PDF]

, 2011
Compared to other major food crops, progress in potato yield as the result of breeding efforts is very slow. Genetic gains cannot be fixed in potato due to obligatory out-breeding.

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.

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.

Allelic diversity of S‑RNase alleles in diploid potato species [PDF]

, 2016
S-ribonucleases (S-RNases) control the pistil specificity of the self-incompatibility (SI) response in the genus Solanum and several other members of the Solanaceae.
