NaPi/SX-RNase segregates as a functional S-RNase and is induced under phosphate deficiency in Nicotiana alata [PDF]
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]
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).

Specific functions of single pistil S-RNases in S-gene homozygous Pyrus germplasm
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]
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

The production of extracellular proteins is regulated by ribonuclease III via two different pathways in Staphylococcus aureus. [PDF]
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
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-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.

Among the Rosaceae species, the gametophytic self-incompatibility (GSI) is controlled by a single multi-allelic S locus, which is composed of the pistil-S and pollen-S genes.

Promoter Analysis of S-Like RNase gene in Transgenic Rice [PDF]
RNases participate in vital cellular functions such as DNA replication, transcription, splicing, and control of translation. S-like ribonucleases (S-like RNases) are homologous to S-ribonucleases (S-RNases), but are not involved in self-incompatibility ...
