The evolution of genome editing technology has significantly transformed agricultural biotechnology, especially through the rapid advancements of CRISPR/Cas9. Creative Biogene’s CRISPR/Cas9 platform specializes in offering innovative solutions for transgene-free genome editing in plants, helping clients create specifically modified crops while circumventing the restrictive regulatory frameworks typical of transgenic crops.

The Need for Transgene-Free Approaches

The challenge in agricultural applications revolves around maintaining trait stability in edited crops. These modifications are crucial for gaining regulatory approval and meeting public concerns. Transgene-free plants not only comply with regulatory standards more readily but also tend to have increased acceptance among consumers and farmers. To address these needs, various strategies can be applied, including:

• Genetic segregation: Through selfing and crossing T plants, CRISPR constructs can be segregated away, thus producing plants that do not contain any transgenes.
• DNA-free systems: Introducing CRISPR components as ribonucleoproteins (RNPs) or RNA eliminates the need for any genetic inserts.
• Fluorescence marker-assisted techniques: These can facilitate the selection of non-transgenic lines.
• Drug-induced removal: Certain chemicals can drive the elimination of unwanted transgenes.
• Transformation methods: Techniques that avoid selection pressures can aid in producing non-transgenic plants.

Overview of Services Offered

Creative Biogene provides tailored services for several crops, including rice, tomato, and Arabidopsis. The process typically involves generating edited plants that are confirmed free of the transgenes through genetic evaluation.

Workflow for Transgene-Free Editing

• Project Design: Tailored approaches based on client requirements.
• Target Selection: Identification of desired genes/loci.
• CRISPR Vector Construction or RNP Preparation: Setting up delivery systems for genome editing.
• Plant Transformation: Initiating the editing process in the plant cells, with or without selection.
• Mutation Identification: Analyzing T plants to assess successful edits.
• Screening of T1 Plants: Employing PCR-based techniques to ensure removal of transgenes, yielding compliant T1 generation plants.
