cytidine/oryza sativa

When cultivated rice seed fall into fields, they may overwinter and spontaneously germinate the next spring. Such germinated plants are termed "volunteer rice." Volunteer grains originating from feed rice varieties may differ in certain traits, such as quality and taste, as compared with those of

RNA editing modifies cytidines (C) to uridines (U) at specific sites in the transcripts of mitochondria and plastids, altering the amino acid specified by the DNA sequence. Here we report the identification of a critical editing factor of mitochondrial nad7 transcript via molecular characterization

BACKGROUND RNA editing is the process whereby an RNA sequence is modified from the sequence of the corresponding DNA template. In the mitochondria of land plants, some cytidines are converted to uridines before translation. Despite substantial study, the molecular biological mechanism by which

Rice blast disease, caused by the fungal pathogen Magnaporthe grisea, is an excellent model system to study plant-fungal interactions and host defense responses. In this study, comprehensive analysis of the rice (Oryza sativa) transcriptome after M. grisea infection was conducted using robust-long

A computational analysis of RNA editing sites was performed on protein-coding sequences of plant mitochondrial genomes from Arabidopsis thaliana, Beta vulgaris, Brassica napus, and Oryza sativa. The distribution of nucleotides around edited and unedited cytidines was compared in 41 nucleotide

BACKGROUND RNA editing by cytidine-to-uridine conversions is an essential step of RNA maturation in plant organelles. Some 30-50 sites of C-to-U RNA editing exist in chloroplasts of flowering plant models like Arabidopsis, rice or tobacco. We now predicted significantly more RNA editing in

RNA editing plays a key posttranscriptional role in gene expression. Existing studies on cytidine-to-uridine RNA editing in plants have focused on maize (Zea mays), rice (Oryza sativa), and Arabidopsis (Arabidopsis thaliana). However, the importance and regulation of RNA editing in several critical

In flowering plants, RNA editing is a posttranscriptional mechanism that converts specific cytidines to uridines in both mitochondrial and plastidial transcripts, altering the information encoded by these genes. Here, we report the molecular characterization of the empty pericarp5 (emp5) mutants in
