Scalable, Flexible, and Cost-Effective Seedling Grafting

Area of Science:

• Plant Molecular Genetics
• Plant Biology
• Developmental Biology

Background:

• Seedling grafting is crucial for studying root-shoot interactions in plants.
• Grafting small, fragile seedlings like Arabidopsis thaliana presents significant technical challenges.
• Existing grafting methods vary in success, difficulty, and cost.

Purpose of the Study:

• To describe a simple, cost-effective, and reusable in-house grafting device for early-stage seedlings.
• To provide a user-friendly protocol for seedling grafting suitable for beginners.
• To facilitate the routine use of seedling grafting in plant molecular genetics laboratories.

Main Methods:

• Fabrication of a reusable grafting device using silicone elastomer mix.
• Detailed procedure for performing seedling grafting with the custom device.
• Cost analysis of materials for device production ($0.47 per device).

Main Results:

• Beginners can achieve successful grafted seedlings within 3 weeks.
• The developed device is reusable and cost-effective.
• The procedure is highly accessible and adaptable for different plant species.

Conclusions:

• This novel grafting device and method significantly lower the barrier to entry for seedling grafting.
• The technique promotes the integration of seedling grafting into standard experimental workflows in plant science.
• The adaptable design allows for potential application in grafting larger plant species.
