Welcome to the CALS Plant Transformation Facility (PTF)

Transgenic plants are vital for both research and agriculture. They help the plant research community test hypotheses, greatly expanding our understanding of plant biology. Transgenic technology may also improve key characteristics of economically important crops, thereby helping both growers and consumers.

Who we are

The Plant Transformation Facility (PTF) is a new service facility of the College of Agriculture and Life Sciences (CALS) and its School of Integrative Plant Science (SIPS). PTF is charged with supporting the plant biology research of Cornell faculty by making transgenic plants of time-consuming or hard-to-transform species with a particular focus on New York State crops. With the explosion of interest in gene editing technologies, much of our work involves performing CRISPR/Cas9-mediated genome modification. PTF is located in B22 Weill Hall on Cornell's Ithaca campus.


Technologies available at PTF

PTF is set-up to do transformation using the following approaches. The method chosen will vary between species and even between some genetic backgrounds of the same species.

  • Agrobacterium
  • Biolistics (gene gun)
  • Protoplasts

Plant species transformed

  • Rice (Nipponbare, Kitaake, and IR64 genetic backgrounds) 
  • Maize (inbred line B104)
  • Wheat (Fielder) 
  • Apple (M.26) 
  • Other. We look forward to collaborating with Cornell faculty on other plant species of interest, with emphasis on those that are not currently addressed at other plant transformation facilities. We are particularly interested in working on crops significant to the New York State agricultural economy.

Those interested in transformation of tomato, potato, Brachypodium distachyon, and Setaria viridis should contact the Biotechnology Center at Boyce Thompson Institute.
