I'm looking for information about the use of dihydrofolate reductase (DHFR)
as a resistance marker for Arabidopsis thaliana.
Does anyone have a working protocol for root transformation using this
marker ? I plan to transform C24 and Landsberg erecta, but information on
any ecotype could be useful. Particularly, what concentration of
methotrexate should be used during shoot regeneration from root
transformation and what concentration is best for testing seedling
Thank you very much.
