Identification of a non-S RNase, a possible ancestral form of S-RNases, in Prunus

Molecular Genetics and Genomics, 2003
This study identifies and characterizes a basic non-S RNase in the styles with stigmas of sweet cherry (Prunus avium L.), a member of the Rosaceae subfamily Amygdaloideae, which has an RNase-based gametophytic self-incompatibility system. Internal sequences of putative non-S RNases (RNase PA1 and PA2) were determined, and a cDNA for PA1 was obtained ...

S-RNase-like Sequences in Styles of Coffea (Rubiaceae). Evidence for S-RNase Based Gametophytic Self-Incompatibility?

Tropical Plant Biology, 2011
Although RNase-based self-incompatibility (SI) is suspected to operate in a wide group of plant families, it has been characterized as the molecular genetic basis of SI in only three distantly related families, Solanaceae, Plantaginaceae, and Rosaceae, all described over a decade ago.

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.

Identification of S-RNase and peroxidase in petunia nectar

Journal of Plant Physiology, 2011
Previous SDS PAGE gel analysis of the floral nectars from petunia and tobacco plants revealed significant differences in the protein patterns. Petunia floral nectar was shown to contain a number of RNase activities by in gel RNase activity assay.

Self-fertile apple resulting from S-RNase gene silencing

Plant Cell Reports, 2003
Self-incompatibility (SI) restricts fertilisation and fruit setting in many tree fruit crops. In apple, we have produced transgenic trees harbouring extra copies of the endogenous S-gene controlling SI. Two independent transgenic genotypes were characterised in detail.

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.

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.

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

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.

Collaborative Non-Self Recognition System in S-RNase–Based Self-Incompatibility

Science, 2010
Dissecting Self-Incompatibility Although the pollen may be available for a flower to fertilize itself, molecular determinants on the pollen and the pistil prevent inbreeding in a process termed self-incompatibility.
