Genome Assembly Strategy Solution

A genome assembly project should not begin with a platform choice alone. It should begin with the biological question, the species, the sample quality, the expected genome complexity, and the downstream analyses the final assembly must support.

CD Genomics provides a Genome Assembly Strategy Solution to help research teams design de novo, chromosome-level, haplotype-resolved, or T2T-like assembly workflows using PacBio, Nanopore, Hi-C, genome annotation, assembly QC review, and downstream-ready bioinformatics.

We help you choose an assembly plan before sequencing begins, so your project is built around the genome resource you actually need.

Start with the Assembly Level Your Research Actually Needs

Many genome assembly pages begin by comparing sequencing platforms. In practice, the better starting point is the assembly level. A microbial genome, a first draft for a non-model species, a chromosome-level plant genome, and a haplotype-resolved animal genome do not need the same plan.

Before recommending a workflow, we help you define what the final assembly must support. A project for gene discovery may need a different assembly and annotation strategy from a project focused on trait mapping, structural variation, pan-genome construction, or population genomics.

T2T-like assembly when repeats, centromeres, and telomeres matter

A T2T-like strategy may be considered when unresolved gaps, long repeats, centromeric regions, telomeric regions, or complex structural regions are central to the study. This is usually a higher-demand project type because it depends heavily on sample quality, read length, assembly strategy, and manual or custom review.

Not every project needs a T2T-like assembly. We help you decide whether this level of resolution is necessary for your research question or whether a chromosome-level or phased assembly would be more practical.

Draft or contig-level assembly for early genome resources

A draft or contig-level assembly may be suitable when your goal is an early reference resource, broad gene discovery, microbial genome reconstruction, or preliminary comparative analysis. It can be useful when the genome is compact, the research question does not require chromosome-scale ordering, or the project is designed as a first step before deeper analysis.

This level can provide a practical starting point, but it may not fully support linkage analysis, chromosome-scale structural interpretation, or complex repeat resolution.

Chromosome-level assembly for linkage, trait, and comparative studies

Chromosome-level assembly is often needed when genomic position matters. This includes trait mapping, breeding research, chromosome evolution, synteny analysis, comparative genomics, and many plant or animal genome projects.

Hi-C scaffolding can help order and orient assembled contigs into chromosome-scale scaffolds. For projects where the final assembly will support downstream mapping or comparative work, chromosome-level structure can be more valuable than a fragmented assembly with high local accuracy but limited long-range organization.

Haplotype-resolved assembly for heterozygous or polyploid genomes

For highly heterozygous, outbred, hybrid, or polyploid organisms, a single collapsed representation may hide important allele- or haplotype-specific structure. In these cases, haplotype-resolved or phased assembly may be useful.

This strategy can be important for plant and animal breeding, allele-specific gene discovery, structural variation analysis, and projects where subgenomes or homologous chromosomes need careful interpretation.
