The genome of the model plant Arabidopsis thaliana has been sequenced
by an international collaboration, The Arabidopsis Genome Initiative. Here
we report the complete sequence of chromosome 5. This chromosome is 26 megabases
long; it is the second largest Arabidopsis chromosome and represents
21% of the sequenced regions of the genome. The sequence of chromosomes 2
and 4 have been reported previously and that of chromosomes
1 and 3, together with an analysis of the complete genome sequence, are reported
in this issue. Analysis of the sequence of chromosome
5 yields further insights into centromere structure and the sequence determinants
of heterochromatin condensation. The 5,874 genes encoded on chromosome 5 reveal
several new functions in plants, and the patterns of gene organization provide
insights into the mechanisms and extent of genome evolution in plants.
