RNA editing of transcripts of a chimeric mitochondrial gene associated with cytoplasmic male-sterility in Brassica.
The orf224 gene is a chimeric open reading frame associated with the Polima or pol cytoplasmic male sterility of Brassica napus. The first 58 codons and 5' upstream region of orf224 are derived from a conventional mitochondrial gene, orfB, while the origin of the remaining portion of the gene is unknown. Transcripts of the orf224 gene were found to be edited at a single site in the region of th...
متن کاملNon-coding RNA may be associated with cytoplasmic male sterility in Silene vulgaris
Cytoplasmic male sterility (CMS) is a widespread phenomenon in flowering plants caused by mitochondrial (mt) genes. CMS genes typically encode novel proteins that interfere with mt functions and can be silenced by nuclear fertility-restorer genes. Although the molecular basis of CMS is well established in a number of crop systems, our understanding of it in natural populations is far more limit...
متن کاملIdentification of a mitochondrial protein associated with cytoplasmic male sterility in petunia.
The petunia fused gene (pcf), which is associated with cytoplasmic male sterility (CMS), is composed of sequences derived from atp9, coxII, and an unidentified reading frame termed urfS. To determine whether the pcf gene is expressed at the protein level, we produced antibodies to synthetic peptides specified by the coxII and urfS portions of the pcf gene. Anti-COXII peptide antibodies recogniz...
متن کاملMOLECULAR CHARACTERIZATION OF THE 16SR II GROUP OF PHYTOPLASMA ASSOCIATED WITH FABA BEAN (Vicia faba L.) IN SAUDI ARABIA
This study was conducted to detect for the first time the occurrence of phytoplasma in symptomatic faba bean plants in Saudi Arabia. Faba bean is one of the most widely grown protein-producing food legumes. Ten leaf and stem samples showing symptoms of phyllody and stunting were collected from plants grown in Agricultural Research Station field Riyadh region, Saudi Arabia during December, 2011....
متن کاملCytoplasmic male sterility in Brassicaceae crops
Brassicaceae crops display strong hybrid vigor, and have long been subject to F1 hybrid breeding. Because the most reliable system of F1 seed production is based on cytoplasmic male sterility (CMS), various types of CMS have been developed and adopted in practice to breed Brassicaceae oil seed and vegetable crops. CMS is a maternally inherited trait encoded in the mitochondrial genome, and the ...
