Clients can expect complimentary counseling and project evaluation to tailor our services to their specific needs.

Importance of Single Nucleotide Changes in Plants

Key agricultural traits are often dictated by single-nucleotide polymorphisms (SNPs) or dominant gain-of-function point mutations. Base editing technology allows for the precise generation of such traits. For example, mutations like ACC-C2186R in rice and ALS-P174F in wheat confer herbicide resistance, making them ideal candidates for base editing applications.

Creative Biogene has recently introduced two main base editors: the cytosine base editor (CBE) and the adenine base editor (ABE). The CBE efficiently facilitates the conversion of C·G pairs to T·A pairs, while the ABE acts on A·T pairs, converting them to G·C pairs in genomic DNA. These advancements allow the integration of base editors with genetic transformation technologies to achieve precise single-base substitutions, significantly impacting precision breeding and agricultural modification.

Expanding Base Editing Capabilities

Our platform is broadening the target scope of the base editing toolkit through the use of Cas9 and Cpf1 variants, each with distinct protospacer-adjacent motif (PAM) specificities. Variants such as VQR-Cas9, EQR-Cas9, and xCas9 enable flexibility in targeting, enhancing the efficacy of editing across diverse plant genomes.

Comprehensive Workflow for Base Editing

1. Project Evaluation: Initial analysis to determine feasibility.
2. Editor Selection: Choosing the appropriate base editor and Cas9 variant based on target base location.
3. sgRNA Design: Custom design and construction of single guide RNAs.
4. Plant Transformation: Utilize methods such as Agrobacterium-mediated transformation, particle bombardment, or PEG-mediated techniques.
5. Mutant Identification: Employ Sanger sequencing and deep amplicon sequencing techniques to confirm successful edits.
6. Optional Off-Target Analysis: Assess potential unintended edits.
7. T1 Seed Harvesting: Collect and analyze the first generation of edited seeds.
