            <STUDY_ABSTRACT>To explore the eukaryotic functional genes, we demonstrated
            metatranscriptomic approach using polyadenylated mRNA extracted from an enriched forest
            soil sample. A total of 93,415,467 bp of cDNA using GS-FLX was sequenced. As a result of
            assembly, 56,084 of putative protein-coding sequence (CDS) fragments were identified.
            This metatranscriptomic approach allowed a first glimpse into the in situ activity of
            the much number of the novel functional genes from eukaryote.</STUDY_ABSTRACT>

            <STUDY_DESCRIPTION>The aim of this study is the exploration of the novel eukaryotic
            functional genes from an environmental sample using metatranscriptomic approach. This
            method is widely applicable to the provision of novel eukaryotic enzymes and proteins of
            potential industrial or medical use. For the extraction of environmental RNA after
            enrichment with wheat bran, the sample was collected from the forest humic soil in the
            site of AIST. The extraction of total RNA and the purification of polyadenylated
            eukaryotic mRNA from the enriched soil sample were used to commercially available kit,
            respectively. The synthesized cDNA sample from the purified mRNA was outsourced to
            Dragon Genomics Center for 454 GS FLX sequencing.</STUDY_DESCRIPTION>
