Compatible pollinations in Solanum chacoense decrease both S-RNase and S-RNase mRNA. [PDF]
PLoS ONE, 2009 Gametophytic self-incompatibility (GSI) allows plants to block fertilization by haploid pollen whose S-allele constitution matches one of the two S-alleles in the diploid styles.

SCFSLF-mediated cytosolic degradation of S-RNase is required for cross-pollen compatibility in S-RNase-based self-incompatibility in Petunia hybrida [PDF]
Frontiers in Genetics, 2014 Many flowering plants adopt self-incompatibility (SI) to maintain their genetic diversity. In species of Solanaceae, Plantaginaceae and Rosaceae, SI is genetically controlled by a single S-locus with multiple haplotypes.

S-RNase Alleles Associated With Self-Compatibility in the Tomato Clade: Structure, Origins, and Expression Plasticity [PDF]
Frontiers in Genetics, 2021 The self-incompatibility (SI) system in the Solanaceae is comprised of cytotoxic pistil S-RNases which are countered by S-locus F-box (SLF) resistance factors found in pollen.

NaPi/SX-RNase segregates as a functional S-RNase and is induced under phosphate deficiency in Nicotiana alata [PDF]
Biologia Plantarum, 2018 In plants, class III T2 RNases involves two groups of structurally similar proteins, but with different biological functions: S-RNases and non-S-RNases.

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

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

Rapid evolution of T2/S-RNase genes in Fragaria linked to multiple transitions from self-incompatibility to self-compatibility [PDF]
Plant Diversity, 2023 The T2/RNase gene family is widespread in eukaryotes, and particular members of this family play critical roles in the gametophytic self-incompatibility (GSI) system in plants.

The influence of the pollination compatibility type on the pistil S-RNase expression in European pear (Pyrus communis) [PDF]
Frontiers in GeneticsThe S-RNase gene plays an essential role in the gametophytic self-incompatibility (GSI) system of Pyrus. It codes for the stylar-expressed S-RNase protein which inhibits the growth of incompatible pollen tubes through cytotoxicity and the induction of ...

Allelic diversity of S-RNase alleles in diploid potato species. [PDF]
Theor Appl Genet, 2016 The S-ribonuclease sequences of 16 S-alleles derived from diploid types of Solanum are presented. A phylogenetic analysis and partial phenotypic analysis support the conclusion that these are functional S-alleles. S-Ribonucleases (S-RNases) control the pistil specificity of the self-incompatibility (SI) response in the genus Solanum and several other ...

Self S-RNase reduces the expression of two pollen-specific COBRA genes to inhibit pollen tube growth in pear [PDF]
Molecular Horticulture, 2023 Due to self-incompatibility (SI) prevents self-fertilization, natural or artificial cross-pollination has been conducted in many orchards to stabilize fruit yield.
