This figure shows number of matches to model organism genes
for Drosophila species genomes (year 2005 assemblies).
Differences in species count from that of D. melanogaster is shown.
- This comparison uses a stringent tBLASTn cutoff of e-10 for
- Matches are made with tBLASTn of eukaryote model organism
proteomes to the genome assembly DNA.
Data are from ftp://eugenes.org/eugenes/genomes/
- These differences may or may not be statistically significant; they
haven't been tested yet. Of more interest, the specific genes
differing may be low or high quality matches. They may or may not
be of biological significance.
- Dsim is off the chart here, as the genome assembly used is
based on lower coverage (3x) for one of several strains sequenced.
- The first Dyak assembly had several unique Yeast genes, due
apparently to to contamination of this assembly
with yeast genome. These have been removed from the analysis.
for blastresults of Dyak chromosome "U" against Sacch. cervisae genome
with many 1kb - 3kb exact or near exact match regions.
- A general loss of gene matches to full proteomes is
difficult to distinguished from incomplete genome sequencing and
assembly, without other information. The Dgri assembly may fall in
that category. See also D. melanogaster genematches chart.
