The large number of ESTs generated for Arabidopsis and rice in recent
years now act as an important complement to whole genome sequencing pr
ojects. The Arabidopsis Genome Initiative has begun a coordinated effo
rt to sequence the entire genome and, as a result, increasing numbers
of large sequence entries can be found in the public databases; in add
ition, the mitochondrial genome of Arabidopsis has been completely seq
uenced. Genome sequencing studies and the public sequence databases ha
ve begun to influence the direction of diverse areas of research from
physiology to evolution.
