Differences in editing of mitochondrial nad3 transcripts from CMS and fertile carrots.

Acta Biochim Pol

Department of Plant Molecular Biology, Institute of Molecular Biology and Biotechnology, Adam Mickiewicz University, Poznań, Poland.

Published: August 2002

A high level of the nucleotide sequence conservation was found for mitochondrial nad3 gene of carrot. Three silent nucleotide substitutions differentiate nad3 open reading frames from cytoplasmic male sterile and male fertile carrots. All these differences are preserved on the RNA level. Partial and silent editing also distinguished both carrots. Three of the C to U conversions were specific to the fertile line. In the two examined carrot lines editing did not affect the mode of alteration of encoded amino acids.

Article Synopsis
  • The study focuses on a fungal genus with over 400 species, revealing limited genetic information mainly in the form of DNA barcodes.
  • Researchers report 42 new mitochondrial genomes alongside 18 previously published ones, highlighting their size variations and complex structures with core genes and introns.
  • Phylogenetic analysis shows six distinct evolutionary branches and identifies mutation hotspots, suggesting positive selection has influenced certain genes critical to the evolution of these fungi, which are important for biocontrol applications.

The family Clausiliidae was proposed as a model for studying the diversity of breeding biology in land snails. This study assembled a nearly complete mitogenome (15,417 bp) for the clausiliid snail . The mitogenome includes 13 protein-coding genes (PCGs), two ribosomal RNAs, and 22 transfer RNAs, with a gene order consistent with other clausiliids.
