Area of Science:

  • Plant Biotechnology
  • Genetics and Genomics
  • Agricultural Science

Background:

  • Developing efficient genetic transformation protocols is crucial for crop improvement.
  • Plum (Prunus domestica) transformation has historically faced challenges, limiting its genetic manipulation.

Purpose of the Study:

  • To establish a high-throughput Agrobacterium-mediated transformation system for plum.
  • To optimize explant source, hormonal treatments, and selection methods for efficient regeneration and transformation.

Main Methods:

  • Hypocotyl slices from zygotic embryos were used as explants.
  • Agrobacterium tumefaciens-mediated transformation followed by co-cultivation on MS medium with 2,4-D.
  • Regeneration and elongation of transgenic shoots using thidiazuron and benzyladenine with kanamycin selection.
