The Molecular and Genetic Bases of S-RNase-Based Self-Incompatibility [PDF]
The majority of flowering plants produce perfect flowers that contain both the male and female reproductive organs in close proximity; consequently, they would have a strong tendency to self-fertilize if there were no mechanisms to prevent them from doing so.

A RNase P Ribozyme Inhibits Gene Expression and Replication of Hepatitis B Virus in Cultured Cells
Hepatitis B virus (HBV), an international public health concern, is a leading viral cause of liver disease, such as hepatocellular carcinoma. Sequence-specific ribozymes derived from ribonuclease P (RNase P) catalytic RNA are being explored for gene ...

Convergent evolution at the gametophytic self-incompatibility system in Malus and Prunus.
S-RNase-based gametophytic self-incompatibility (GSI) has evolved once before the split of the Asteridae and Rosidae. This conclusion is based on the phylogenetic history of the S-RNase that determines pistil specificity.

Sequence characterization and evolutionary analysis of S-RNase gene among five genera Pomoideae [PDF]
[Objective] In order to avoid self-pollination, self-incompatibility is a common phenomenon in 5 genera in Pyridae fruit trees during evolution. In order to understand the latest isolation and identification of S-RNase gene in pear incompatibility, we ...

Differential strengths of selection on S-RNases from Physalis and Solanum(Solanaceae) [PDF]
The S-RNases of the Solanaceae are highly polymorphic self-incompatibility (S-) alleles subject to strong balancing selection. Relatively recent diversification of S-alleles has occurred in the genus Physalis following a historical restriction of S-allele diversity.

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

A Tobacco S-like RNase Inhibits Hyphal Elongation of Plant Pathogens
Ribonuclease (RNase) NE gene expression is induced in tobacco leaves in response to Phytophthora parasitica. Using antibodies directed against RNase NE, we demonstrate that RNase NE is extracellular at the early steps of the interaction, while the fungal

Identification of S-genotypes and a novel S-RNase in 84 native Chinese pear accessions
The Chinese pear (Pyrus spp.) exhibits typical gametophytic self-incompatibility (GSI), which inhibits self-crossing and promotes out-crossing, similar to other fruit species in the Rosaceae family.

Identification of regions in which positive selection may operate in S‐RNase of Rosaceae: Implication for S‐allele‐specific recognition sites in S‐RNase [PDF]
A stylar S‐RNase is associated with gametophytic self‐incompatibility in the Rosaceae, Solanaceae, and Scrophulariaceae. This S‐RNase is responsible for S‐allele‐specific recognition in the self‐incompatible reaction, but how it functions in specific discrimination is not clear. Window analysis of the numbers of synonymous (dS ) and non‐synonymous (dN )

Cryo-EM structure of catalytic ribonucleoprotein complex RNase MRP
Ribozyme-based RNase MRP is an essential eukaryotic enzyme involved in the maturation of rRNA and is evolutionarily related to RNase P. Here, the authors present the 3.0 Å cryo-EM structure of the S.
