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 ...

Molecular Biology Of S-Rnase-Based Self-Incompatibility

2008
Many Flowering Plants Have Developed Self-Incompatibility (Si) Systems To Avoid Inbreeding And To Promote Out-Crossing. Among The Various Si Systems, Gametophytic Si (Gsi) In The Solanaceae, Plantaginaceae And Rosaceae Is Believed To Be The Most Common Type, In Which The Specificity Of Si Response Is Controlled By A Single Polymorphic Locus, Termed The

Comparing Models For S-Rnase-Based Self-Incompatibility

2008
S-Rnase-Based Self-Incompatibility (Si) Is Known To Occur In Three Families Of Flowering Plants: Solanaceae, Rosaceae And Plantaginaceae. It Is The Most Widely Distributed Si System Described So Far. It Is A Single-Locus Gametophytic System. Gene Pairs At The S-Locus Determine S-Specificity On The Pistil And The Pollen Sides Of Si.
