DNA sequences of the A. thaliana chromosomes I-V were downloaded 
from NCBI in November 2001.

The "December 2001" version of the Arabidopsis thaliana 
section (athrep.ref) of Repbase Update was used for 
annotation of the chromosomes. The annotation 
shows localization of transposable elements in the 
chromosomes. These elements have been identified
by using the BLAST and CENSOR searches.

Each line in the annotation represents a chromosomal
fragment that can be classified as a transposable or
noncoding repetitive element. Every line is composed
of 5 columns that, in order, represent the following
data:
1. Fragment start-ends positions in the chromosome
2. Name of a transposable or repetitive element in Repbase Update
   most similar to the fragment
3. Fragment start-end positions in the Repbase Udate element
4. Orientation of the element, 'd' for direct, 'c' for complement
5. Percent identity between the chromosomal fragment and transposable 
   element from Repbase Update.

DNA sequence of any chromosomal fragment annotated as a transposable
or repetitive element can be viewed in a separate window after
clicking on the fragment's chromosomal positions.

Your browser's window shows the annotation for 1 Mb long chromosomal 
segments. You may jump from one chromosomal segment to another using
green buttons marked by numbers. The button's number indicates a
chromosomal segment number.
