Method "Whole genome shotgun sequencing and an oriented walking strategy were used to sequence the genome of O. tauri strain OTH95." "The data sources used to complement the ab initio part of EuGene were composed of O. tauri expressed sequence tags (ESTs), proteins, and genomic sequences. ESTs sequenced over the course of the project were aligned on the genome and used as the most reliable source of extrinsic information. For BlastX, the Swissprot protein dataset (v. 42), C. merolae proteins (Matsuzaki et al., 2004 PMID 15071595), publicly available C. reinhardtii proteins, and predicted proteins from Sargasso Sea environmental sequences (Venter et al., 2004 PMID 15001713) were used in a decreasing order of priority to avoid error propagation, because the latter dataset is the least reliable."
Comments "As shown in Fig.2 and Table 1, 8,166 protein-coding genes were predicted in the nuclear genome, making O. tauri the most gene dense free-living eukaryote known to date." "[Researchers] found that 6,265 genes are supported by homology with known genes in public databases (e-value <10^-5), of which the majority (46%) were most similar to plant orthologs (Fig. 3)."
