Current genome sequencing techniques are expensive, and it is still a major challenge to obtain an individual
whole-genome sequence. To reduce the cost of sequencing, this paper introduced a high-throughput sequencing strategy
using a three-dimensional mixing-pools based on the cube. Following the strategy, BAC clones were injected into each
vertex of the cube, and sequencing of each plane provided information about multiple clones, thereby significantly
reducing the cost of sequencing. In addition, Velvet was used to assemble the sequencing data. The scaffold generated
from Velvet contained a number of contigs, which were orderless. Therefore, to address this problem, a scaffold
assembly algorithm based on multi-way trees was used. The algorithm used a multi-way tree to build the framework of
chromosomes, and subsequently, the frame was filled to complete the scaffold assembly. This algorithm alone
outperformed Velvet in the assembling of a scaffold.
