A Collection of Poplar Full-Length cDNAs

Abstract

We have been collecting poplar full-length cDNAs. In 2004, we reported several thousands of clones from leaves of axenically grown poplar (Populus nigra var. italica) subjected to environmental abiotic stress treatments. The population of P. nigra expressed sequence tags (ESTs) has grown ever since, resulting in more than 13,000 non-redundant clones which originate from various organs of a field-grown stand and stress-treated in vitro leaves. Our poplar full-length cDNAs represent about 30% of the whole population of genes estimated in Populus. We will discuss similarity and specificity between trees and herbaceous model plants in the light of comparative genomics.
