Export of Mitochondrial and Chloroplast Genes

3.1K
A eukaryotic cell can have up to three different types of genetic systems: nuclear, mitochondrial, and chloroplast. During evolution, organelles have exported many genes to the nucleus; this transfer is still ongoing in some plant species. Approximately 18% of the Arabidopsis thaliana nuclear genome is thought to be derived from the chloroplast’s cyanobacterial ancestor, and around 75% of the yeast genome derived from the mitochondria’s bacterial ancestor. This export has occurred...

Summary

A new tool, Tbl2KnownGene, converts NCBI .tbl files into UCSC Known Genes annotation tables. This facilitates genomic analysis for organisms lacking direct UCSC annotations, like Arabidopsis.

Area of Science:

  • Bioinformatics
  • Genomics
  • Computational Biology

Background:

  • The UCSC Known Genes (knownGene.txt) schema is a standard for genomic analysis.
  • Many popular model organisms lack publicly available sequence and annotation data in this format.
  • This limits the use of standard downstream analysis tools and scripts.

Purpose of the Study:

  • To introduce Tbl2KnownGene, a novel parser designed to process NCBI .tbl files.
  • To generate UCSC Known Genes annotation feature tables from .tbl file data.
  • To address the need for standardized gene annotation data in model organisms.

Main Methods:

  • Development of a .tbl file parser named Tbl2KnownGene.
  • Algorithm designed to read and interpret NCBI .tbl file contents.
  • Output generation of UCSC Known Genes annotation feature tables.

Main Results:

  • Successfully tested the Tbl2KnownGene algorithm with Arabidopsis (TAIR10) chromosome datasets.
  • Demonstrated the parser's ability to convert .tbl data into the knownGene.txt format.
  • Validated the utility of the parser for organisms with similar .tbl annotations.

Conclusions:

  • Tbl2KnownGene provides a valuable solution for creating UCSC Known Genes annotations.
  • The tool enhances genomic data accessibility for under-annotated model organisms.
  • Facilitates broader application of established bioinformatics analysis pipelines.
