Figure 4
Coding content of the fly genome
Each predicted gene in the genome is depicted as a box color-coded by similarity to genes from mammals,
C. elegans, and
S. cerevisiae. A legend appears at the end of each chromosome arm describing the components of each panel. In order from the top, they are (A) scale in megabases, (B) polytene chromosome divisions, (C) GC content in a range from 25 to 65%, (D) transposable elements, and genes on the (E) plus and (F) minus strands. The width of each gene element represents the total genomic length of the transcription unit. The height of each gene element represents EST coverage: The shortest boxes have no EST matches, medium-size boxes have 1 to 12 EST matches, and the tallest boxes have 13 or more EST matches. The color code for sequence similarity appears on each side of the fold-out figure. The graphics for this figure were prepared using gff2ps (
68). Each gene has been assigned a FlyBase identifier (FBgn) in addition to the Celera identifier (CT#). Access to supporting information on each gene is available through FlyBase at
http://flybase.bio.indiana.edu. These data are also available through a graphical viewing tool at FlyBase and Celera (
www.celera.com), with additional supporting information.
