Computational analysis demonstrates accurate de novo genome assembly in Pichia stipitis, highlighting a memory-efficient graph traversal approach without explicit error correction.

Key Points

To introduce Meraculous, a new algorithm designed for de novo whole-genome assembly using short paired-end sequence reads without requiring an explicit error correction step.
Utilized an efficient traversal of a k-mer de Bruijn subgraph containing unique high-quality extensions alongside a novel memory-efficient hashing scheme.
Assembled paired 75-bp Illumina reads derived from the 15.4-Mb genome of the haploid yeast Pichia stipitis, followed by contig ordering and orientation using paired reads (spanning ~280 bp and ~3.2 kbp) and fosmid ends.
Recovered over 95% of the 15.4-Mb Pichia stipitis genome with zero errors.
Achieved a contig N50 greater than 101 kilobases and a scaffold N50 greater than 269 kilobases, with fosmid ends successfully reconstructing entire chromosomes.
