A genome-scale metabolic network reconstruction for Clostridium acetobutylicum (ATCC 824) was created using a new semi-automated reverse engineering algorithm. This invention includes algorithms and software that can reconstruct genome-scale metabolic networks for cell-types available through the Kyoto Encyclopedia of Genes and Genomes. This method can also be used to complete partial metabolic networks and cell signaling networks where adequate starting information base is available. The software may use a semi-automated approach which uses a priori knowledge of the cell-type from the user. Upon completion, the program output is a genome-scale stoichiometric matrix capable of cell growth in silico. The invention also includes methods for developing flux constraints and reducing the number of possible solutions to an under-determined system by applying specific proton flux states and identifying numerically-determined sub-systems. Although the model-building and analysis tools described in this invention were initially applied to C. acetobutylicum, the novel algorithms and software can be applied universally.

The invention relates to the genome sequencing technology field and especially relates to a method for accurately predicting a BSA-seq candidate gene in a low-density SNP genomic region. BSA-seq has alow-density SNP region near a candidate interval. Through comparing SNPs between two parents, an SNP list is strictly filtered to find a low-density region, and then, a corresponding candidate interval when a confidence interval is 95% and a low-density candidate interval are used, and a genome annotation website is used to annotate the genes in a candidate region. A candidate region variation point function is annotated so as to obtain a gene with functional variation such as frameshift variation and the like, and the gene is determined to be a candidate gene. The method can be used to makeup for the false positive of the candidate region due to the region with a small difference in a genome, and the real candidate interval is acquired.
