To download genomic sequences or ESTs for any organism (in various
formats) you can use NCBI Taxonomy Browser:
you can use taxonomy id to access different organisms, Arabidopsis for
or by direct web link:
assembled genomes can be accessed via ftp:
To download large amount of selected sequences (ESTs for example) you
can use batch Entrez:
(select EST for EST, it's critical)
It seems, to solve the problem you describe, you don't need to use
bioperl. NCBI GenBank Entrez provides all necessary tools to work on
these simple and frequent tasks.
