Area of Science:

  • Plant Science
  • Genomics
  • Biotechnology

Background:

  • High-throughput genotype screening is crucial in the post-genomic era.
  • Manual tissue collection from individual plants is a bottleneck in plant science research.
  • Current methods limit the efficiency of large-scale genetic analysis in plants.

Purpose of the Study:

  • To introduce a novel, automated method for harvesting plant tissue samples.
  • To overcome the limitations of manual sample collection in high-throughput genotyping pipelines.
  • To facilitate non-destructive tissue harvesting for subsequent plant growth and analysis.

Main Methods:

  • The Ice-Cap method utilizes ice to capture tissue samples from living seedlings.
  • All procedures, including seed planting, seedling growth, and tissue harvesting, are performed in a 96-well format.
