CD Biosynsis offers a premier, integrated platform for Synechococcus spp. Genome Editing Services, providing researchers with advanced tools to manipulate one of the most important model organisms in cyanobacterial research. Synechococcus species, such as S. elongatus PCC 7942 and S. sp. PCC 7002, are widely utilized as photosynthetic chassis for the production of biofuels, specialty chemicals, and pigments due to their rapid growth and relatively simple genetic structure. Our services are specifically designed to overcome the hurdles of cyanobacterial engineering, such as polyploidy and chromosomal segregation. By utilizing site-specific nucleases and optimized delivery systems, we empower our clients to achieve precise, stable, and homozygous genetic modifications.
Our expert team provides end-to-end support for Synechococcus engineering, moving beyond traditional homologous recombination toward rational, CRISPR-based design. We utilize various delivery modalities—including natural transformation, bacterial conjugation, and electroporation—to ensure high editing efficiency. Our workflow integrates sophisticated codon optimization and regulatory element selection, ensuring that every engineered strain maintains optimal photosynthetic efficiency and genetic stability. Whether you are conducting fundamental research into circadian rhythms or developing industrial strains for carbon sequestration, our platform provides the precision and reliability needed to achieve your goals.
Get a QuoteOptimizing Synechococcus spp. involves managing the distribution of photosynthetic energy and carbon flux. A major challenge in cyanobacterial editing is the presence of multiple genome copies (polyploidy), which often requires lengthy periods of selective pressure to achieve full segregation. Our genome editing solutions solve this by utilizing CRISPR-Cas systems to provide active selective pressure against wild-type alleles, significantly accelerating the generation of homozygous mutants.
Our strategic approach focuses on the rational design of metabolic pathways. By applying systems biology principles, we identify specific genetic targets that, when modified, can redirect carbon away from storage compounds like glycogen toward target metabolites such as isobutanol, sucrose, or ethylene. This targeted strategy ensures that engineered strains achieve high specific productivity while remaining resilient under industrial cultivation conditions, bridging the gap between laboratory-scale discovery and sustainable biomanufacturing.
Optimized CRISPR-Cas9 and Cas12a platforms specifically tailored to minimize nuclease toxicity in cyanobacteria while ensuring high editing efficiency.
Permanent biallelic disruption of target genes to eliminate metabolic competitors or study essential functional genomics in cyanobacteria.
Site-specific integration of exogenous genes into validated "Neutral Sites" (NS) to ensure stable expression without disrupting host fitness.
Non-mutagenic, tunable transcriptional silencing for balancing metabolic flux and studying genes essential for photosynthesis.
Precise single-nucleotide conversion for targeted protein engineering and "scarless" point mutations in the cyanobacterial genome.
Our pipeline is optimized to handle the unique polyploid nature of Synechococcus to ensure the delivery of fully segregated mutants.

Technical insights for your Synechococcus engineering project.
Contact Us1. How do you ensure full segregation in polyploid Synechococcus?
We utilize the CRISPR nuclease to specifically target and eliminate wild-type chromosomal copies. This forces the cell to only maintain the edited alleles, achieving homozygosity much faster than traditional methods.
2. Which Synechococcus strains do you support?
We have established protocols for S. elongatus PCC 7942, Synechococcus sp. PCC 7002, and can adapt our methods for other marine or freshwater isolates.
3. Is Cas9 toxic to cyanobacterial cells?
High-level expression of Cas9 can be toxic. We mitigate this by using inducible promoters to tightly regulate expression or by utilizing Cas12a (Cpf1), which is often better tolerated.
4. What are Neutral Sites (NS)?
Neutral sites are genomic locations where exogenous DNA can be integrated without significantly affecting the growth rate or metabolic health of the host under standard conditions.
5. Do you provide help with codon optimization for transgenes?
Absolutely. We provide comprehensive codon optimization using proprietary cyanobacterial-specific matrices to ensure maximal translational throughput.
6. What is the typical turnaround time for a knockout strain?
A standard single-gene knockout project from design to homozygous strain delivery typically takes 10 to 14 weeks.
7. Can you perform multiplexed editing for metabolic pathways?
Yes, we can target multiple loci simultaneously using poly-cistronic gRNA arrays, which is essential for redirecting complex metabolic carbon flux.
8. Is it possible to generate marker-free modified strains?
Yes. By utilizing RNP delivery or curable vectors that can be removed after the edit is confirmed, we can provide modified strains free of permanent antibiotic resistance markers.
CRISPR-Cas9 technology represents a transformative advancement in gene editing techniques. The main function of the system is to precisely cut DNA sequences by combining guide RNA (gRNA) with the Cas9 protein. This technology became a mainstream genome editing tool quickly after its 2012 introduction because of its efficient, simple and low-cost nature.
The CRISPR gene editing system with its Cas9 version stands as a vital instrument for current biological research. CRISPR technology enables gene knockout (KO) through permanent gene expression blockage achieved by sequence disruption. Various scientific domains including disease modeling and drug screening employ this technology to study gene functions. CRISPR KO technology demonstrates high efficiency and precision but requires confirmation and verification post-implementation because unsatisfactory editing may produce off-target effects or incomplete gene knockouts which impact experimental result reliability. For precise and efficient Gene Editing Services - CD Biosynsis, Biosynsis offers comprehensive solutions tailored to your research needs.
The CRISPR-Cas9 knockout cell line was developed using CRISPR/Cas9 gene editing to allow scientists to remove genes accurately for research on gene function and disease models and pharmaceutical discovery. Genetic research considers this technology essential due to its high efficiency together with simple operation and broad usability.
