A Tobacco S-like RNase Inhibits Hyphal Elongation of Plant Pathogens

Molecular Plant-Microbe Interactions, 2002
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

Horticultural Plant Journal, 2022
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]

FEBS Letters, 1998
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

Nature Communications, 2020
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.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Flowering and pollination studies with European plum (Prunus domestica L.) cultivars [PDF]

, 2010
One of the most important factors affecting the financial outcome of commercial fruit growing is the success of pollination and fertilization, which in turn are dependent on weather conditions, activity of pollinators and the compatibility and overlap in

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

FEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Genotype and phenotype of Nicotiana alata x Nicotina rastroensis [PDF]

, 2004
only availableGametophytic self-incompability (SI) is a process which enables plants to prevent inbreeding depression by rejecting self-pollen and pollen from closely related individuals. S-specific pollen rejection is controlled on a multi-allelic locus,

A conformational RNA zipper promotes intron ejection during non-conventional XBP1 mRNA splicing. [PDF]

, 2015
The kinase/endonuclease IRE1 is the most conserved signal transducer of the unfolded protein response (UPR), an intracellular signaling network that monitors and regulates the protein folding capacity of the endoplasmic reticulum (ER).

In Vitro Function of S RNases in Lycopersicon peruvianum

Molecules and Cells, 2001
S RNases are products of the S locus that are expressed in the stylar tissue of Lycopersicon peruvianum with the gametophytic self-incompatibility (SI) system. Two S RNases (S12 and Sa) with RNase activity from the S12Sa genotype of L. peruvianum were purified using gel filtration and cation-exchange chromatography.
