Localization of human RNase Z isoforms: dual nuclear/mitochondrial targeting of the ELAC2 gene product by alternative translation initiation. [PDF]
PLoS ONE, 2011 RNase Z is an endonuclease responsible for the removal of 3' extensions from tRNA precursors, an essential step in tRNA biogenesis. Human cells contain a long form (RNase Z(L)) encoded by ELAC2, and a short form (RNase Z(S); ELAC1).

Scientific Reports, 2021 In Rosaceae species, two gametophytic self-incompatibility (GSI) mechanisms are described, the Prunus self-recognition system and the Maleae (Malus/Pyrus/Sorbus) non-self- recognition system.

Overcoming Self-Incompatibility in Diploid Potato Using CRISPR-Cas9
Frontiers in Plant Science, 2019 Potato breeding can be redirected to a diploid inbred/F1 hybrid variety breeding strategy if self-compatibility can be introduced into diploid germplasm.

S-RNase gene of Nicotiana alata is expressed in developing pollen. [PDF]
The Plant Cell, 1993 In the solanaceous plant Nicotiana alata, self-incompatibility is controlled by a single, multiallelic locus (S locus) expressed in both pollen and pistil. Previously, we have shown cosegregation between alleles of the S locus and alleles of a gene that encodes a glycoprotein with ribonuclease activity (S-RNase).

Ornithine decarboxylase genes contribute to S-RNase-independent pollen rejection [PDF]
Plant Physiology, 2021 Abstract Unilateral incompatibility (UI) manifests as pollen rejection in the pistil, typically when self-incompatible (SI) species are pollinated by self-compatible (SC) relatives. In the Solanaceae, UI occurs when pollen lack resistance to stylar S-RNases, but other, S-RNase-independent mechanisms exist.

The Scientific World Journal, 2014 Many flowering plants exhibit an important intraspecific reproductive barrier phenomenon, that is, self-incompatibility (SI), in which S-RNase genes play a significant role.

تعیین آللوتیپ ژن S-RNase و ناحیه پیشبر ژن MdMYB10 در چند ژنوتیپ سیب (Malus spp.) [PDF]
Majallah-i ̒Ulum-i Bāghbānī, 2022 سیب (Malus spp.) یکی از مهمترین درختان میوه مناطق معتدله است. رنگ گوشت میوه سیب، از سفید تا قرمز متغیر است و تجمع مقدار بالایی از آنتوسیانین باعث قرمز بودن گوشت میوه آن میباشد، چنین افزایشی در مقدار آنتوسیانین در بسیاری از موارد به دلیل بیان بالای ژن ...

Frontiers in Plant Science, 2022 Fragaria viridis exhibits S-RNase-based gametophytic self-incompatibility, in which S-RNase is the major factor inhibiting pollen tube growth. However, the pathways involved in and the immediate causes of the inhibition of pollen tube growth remain ...

S-RNase–mediated Gametophytic Self-Incompatibility is Ancestral in Eudicots [PDF]
Molecular Biology and Evolution, 2002 The evolutionary relationship between self-incompatibility systems in different families of flowering plants has long been a topic of interest. Physiological differences in the mode of gene action and the enormous sequence differences between genes with different modes of action suggest that many instances of self-incompatibility have arisen ...

Protomer alignment modulates specificity of RNA substrate recognition by Ire1
eLife, 2021 The unfolded protein response (UPR) maintains protein folding homeostasis in the endoplasmic reticulum (ER). In metazoan cells, the Ire1 branch of the UPR initiates two functional outputs—non-conventional mRNA splicing and selective mRNA decay (RIDD). By
