Özet

Procedures were developed for rapid and prolific adventitious shoot regeneration of Arabidopsis thaliana (L.) Heynh ecotypes ''Landsberg erect'' and ''C24'' from cotyledon explants at 90-100% efficiency. Immature cotyledons had the highest shoot regeneration efficiency. Prolific regeneration was achieved in Murashige and Skoog medium (MS) supplemented with 0.1-0.4 mg(-1) naphthalene acetic acid (NAA) and 1.0 mg(-1) 6-benzylaminopurine (BAP) within 2 weeks. The regenerated plants had a normal phenotype and produced fertile flowers and set seeds. The above regeneration protocol was used to develop a transformation method using disarmed strains of Agrobacterium tumefaciens strains pGV3850::pH1121 based on kanamycin (Km) selection. Transgenic shoots were produced within 2-3 weeks after inoculation. Transformation of shoots was confirmed by GUS histochemical assay, as well as southern blot hybridization.
