Stable Transformation Service

Stable transformation is central to Arabidopsis research, enabling researchers to generate heritable transgenic lines for long-term genetic studies. Our service is based on the widely used Agrobacterium-mediated floral dip method, which has been refined over decades for high reproducibility and efficiency.

Unlike tissue culture-based methods, the floral dip method requires no callus induction or regeneration, significantly simplifying the process and reducing the risk of somaclonal variation. This method allows for rapid generation of transgenic seeds (T1) in just weeks, enabling rapid downstream analysis.

About Arabidopsis thaliana Transformation – Background Information

Arabidopsis thaliana, also known as mouse-ear cress, is the premier model organism in plant biology. Its relatively small genome (135 Mbp), short life cycle, and exceptional adaptability to various environments—including growth rooms, chambers, greenhouses, and even window ledges—make it an ideal biological system for studying plant genetics, evolution, and development.

The most widely used method for generating stable transgenic Arabidopsis thaliana is the Agrobacterium-mediated floral dip. During this process:

  • Infiltration: Inflorescences of "T0" plants are immersed in or sprayed with a suspension of Agrobacterium tumefaciens (typically the GV3101 strain) carrying a specific transformation vector.
  • Integration: The Agrobacterium invades ovules through the stylar canal, integrating the T-DNA into the plant genome.
  • Selection: Following maturation, seeds from the T0 plants are collected and screened on selection plates containing specific antibiotics or herbicides to identify positive "T1" individuals.

Compared to tissue culture-based methods, the floral dip requires minimal labor and simple equipment while providing high-efficiency results.

Our Arabidopsis thaliana transformation platform supports a broad spectrum of research goals, from fundamental genetics to translational agricultural science:

  • Gene Function & CRISPR Editing: Functional validation of orthologous genes from diverse crop species and precise CRISPR/Cas9-mediated gene knockout or transcriptional regulation studies.
  • Engineering Stress Tolerance: Evaluation of transgenic lines for enhanced resistance to abiotic stresses (e.g., salinity, drought, extreme temperatures) and biotic stresses (e.g., bacterial and fungal pathogens).
  • Regulatory & Promoter Studies: Spatiotemporal evaluation of promoter activity and the study of complex gene regulatory networks.
  • Protein Interaction & Localization: High-resolution subcellular localization and interaction analysis (protein-protein or protein-DNA) using specialized GUS, LUC, or fluorescence protein (GFP/YFP/mCherry) fusion systems.
