Basic RNases of wild almond (Prunus webbii): Cloning and characterization of six new S-RNase and one “non-S RNase” genes

Journal of Plant Physiology, 2009
In order to investigate the S-RNase allele structure of a Prunus webbii population from the Montenegrin region of the Balkans, we analyzed 10 Prunus webbii accessions. We detected 10 different S-RNase allelic variants and obtained the nucleotide sequences for six S-RNases.

Evolutionary analysis of S-RNase genes from Rosaceae species

Molecular Genetics and Genomics, 2002
Eight new cDNA sequences for S-RNases were cloned and analysed from almond (Prunus dulcis) cultivars of European origin, and compared to published sequences from other Rosaceae species. Insertions/deletions of 10-20 amino acid residues were detected in the RC4 and C5 domains of S-RNases from almond and sweet cherry.

New views of S-RNase-based self-incompatibility

Current Opinion in Plant Biology, 2006
S-RNase-based self-incompatibility (SI) is the most widespread form of genetically controlled mate selection in plants. S-RNase controls pollination specificity in the pistil, while the newly discovered SLF/SFB controls pollination specificity in the pollen.

Generation of self-compatible diploid potato by knockout of S-RNase

Nature Plants, 2018
Re-domestication of potato into an inbred line-based diploid crop propagated by seed represents a promising alternative to traditional clonal propagation of tetraploid potato, but self-incompatibility has hindered the development of inbred lines.

S-RNases and sexual incompatibility: structure, functions, and evolutionary perspectives

Molecular Phylogenetics and Evolution, 2003
S-RNase-based gametophytic self-incompatibility appears to be the most phylogenetically widespread form of self-incompatibility found in the angiosperms, having been reported in the Solanaceae, Scrophulariaceae, and Rosaceae. This intraspecific breeding barrier is controlled by a single genetic locus termed S. Rejection of self-pollen has been shown to

Identification of the pollen determinant of S-RNase-mediated self-incompatibility

Nature, 2004
Many flowering plants have adopted self-incompatibility mechanisms to prevent inbreeding and promote out-crosses. In the Solanaceae, Rosaceae and Scrophulariaceae, two separate genes at the highly polymorphic S-locus control self-incompatibility interactions: the S-RNase gene encodes the pistil determinant and the previously unidentified S-gene encodes

Cloning and characterization of cDNAs encoding S-RNases from almond (Prunus dulcis): primary structural features and sequence diversity of the S-RNases in Rosaceae

Molecular and General Genetics MGG, 1998
cDNAs encoding three S-RNases of almond (Prunus dulcis), which belongs to the family Rosaceae, were cloned and sequenced. The comparison of amino acid sequences between the S-RNases of almond and those of other rosaceous species showed that the amino acid sequences of the rosaceous S-RNases are highly divergent, and intra-subfamilial similarities are ...

Identification and evolutionary analysis of a relic S-RNase in Antirrhinum

Sexual Plant Reproduction, 2003
In several gametophytic self-incompatible species of the Solanaceae, a group of RNases named relic S-RNase has been identified that belong to the S-RNase lineage but are no longer involved in self-incompatibility. However, their function, evolution and presence in the Scrophulariaceae remained largely unknown.

Diversification and distinctive structural features of S-RNase alleles in the genus Solanum

Molecular Genetics and Genomics, 2014
The multigenic and multiallelic S-locus in plants is responsible for the gametophytic self-incompatibility system, which is important to prevent the detrimental effects of self-fertilization and inbreeding depression. Several studies have discussed the importance of punctual mutations, recombination, and natural selection in the generation of allelic ...

Compartmentalization of S-RNase and HT-B degradation in self-incompatible Nicotiana

Nature, 2006
Pollen-pistil interactions are crucial for controlling plant mating. For example, S-RNase-based self-incompatibility prevents inbreeding in diverse angiosperm species. S-RNases are thought to function as specific cytotoxins that inhibit pollen that has an S-haplotype that matches one of those in the pistil.
