High efficiency Agrobacterium tumefaciens-mediated transformation of Arabidopsis thaliana leaf and cotyledon explants.
A highly efficient and fast Agrobacterium-mediated leaf disc transformation system for the Arabidopsis thaliana L. genotype C24 was developed. This protocol is also amenable to other ecotypes - as could be shown for Landsberg erecta and Wassllewskija. Besides the hygromycin selection also the G418 and kanamycin selection were established. Furthermore the described procedure is appliable not only to leaf explants but also to expanded cotyledons which proved to be an excellent alternative as explant source for transformation experiments.
