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.

Lack of S-RNase-Based Gametophytic Self-Incompatibility in Orchids Suggests That This System Evolved after the Monocot-Eudicot Split. [PDF]
Front Plant Sci, 2017 Self-incompatibility (SI) is found in approximately 40% of flowering plant species and at least 100 families. Although orchids belong to the largest angiosperm family, only 10% of orchid species present SI and have gametophytic SI (GSI).

Apple Cultivation and Breeding in Afghanistan: S-RNase Genotypes and Search System for Suitable Cultivar Combination [PDF]
International Journal of Agronomy, 2016 We investigated S-RNase genotypes of nine useful Afghan apple cultivars including six original cultivars and one rootstock. We also determined S-RNase genotypes of 11 apple cultivars and lineages and seven rootstocks in Japan. We speculated regarding the

Allelic diversity of S-RNase alleles in diploid potato species. [PDF]
Theor Appl Genet, 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.

Specific functions of single pistil S-RNases in S-gene homozygous Pyrus germplasm
BMC Plant Biology, 2023 Gametophytic self-incompatibility (SI) is regulated by S-allele recognition; that is, pollen in a style with the same S-genotype will undergo programmed cell death and stop growing so that it is unable to complete double fertilization, ultimately ...

Expression and trans-specific polymorphism of self-incompatibility RNases in coffea (Rubiaceae). [PDF]
PLoS ONE, 2011 Self-incompatibility (SI) is widespread in the angiosperms, but identifying the biochemical components of SI mechanisms has proven to be difficult in most lineages. Coffea (coffee; Rubiaceae) is a genus of old-world tropical understory trees in which the

Compatibility and incompatibility in S-RNase-based systems. [PDF]
Ann Bot, 2011 Background S-RNase-based self-incompatibility (SI) occurs in the Solanaceae, Rosaceae and Plantaginaceae. In all three families, compatibility is controlled by a polymorphic S-locus encoding at least two genes.

The production of extracellular proteins is regulated by ribonuclease III via two different pathways in Staphylococcus aureus. [PDF]
PLoS ONE, 2011 Staphylococcus aureus ribonuclease III belongs to the enzyme family known to degrade double-stranded RNAs. It has previously been reported that RNase III cannot influence cell growth but regulates virulence gene expression in S. aureus.

Characterization of one new non-S-RNase of Armeniaca cathayana
Czech Journal of Genetics and Plant Breeding, 2019 Armeniaca cathayana, a new species described in 2010, belongs to gametophytic self-incompatibility (GSI) system which is under S-allele control. One new non-S-ribonuclease (non-S-RNase) was found in A. cathayana through comparing its nucleotide and amino

Proteins Rpr2 and Pop3 increase the activity and thermal stability of yeast RNase P
RNA Biology, 2023 RNA-based enzyme RNase P is a ribonucleoprotein complex responsible primarily for 5’-maturation of tRNAs. S. cerevisiae RNase P comprises a catalytic RNA component and nine proteins. The assembly and maturation of S.
