The aim of our work was to obtain Althaea officinalis L. «hairy» root culture with human interferon α2b gene (ifn- α2b), to measure fructans content and antiviral activity of extracts from the transgenic roots. Transformation of leaf and root explants was carried out by means of Agrobacterium rhizogenes-mediated transformation. Antiviral activity was measured by the reduction in cytopathic effect of vesicular stomatitis virus (Indiana strain) in bovine kidney cells line MDBK.

Transformation frequency was 100% for leaf and root explants. RT-PCR confirmed ifn- α2b gene transcription. The clones of transgenic roots differed in mass increasing from 0, 036 ± 0,008 up to 0,371 ± 0,019 g in 30 days cultivation and in fructan synthesis from 67,2± 4,47 up to 154,6 ± 6,62 mg/g roots dry weight.

Extracts from «hairy»roots culture were characterized by high antiviral activity against vesicular stomatitis virus — up to 26 000 IU/ g of roots fresh weight.

In some cases the genetic transformation shown to lead increasing the growth rate and increasing the level of fructan synthesis in transgenic A. officinalis roots. Extracts from cultivated in vitro marshmallow transgenic roots were characterized by high level of antiviral activity against vesicular stomatitis virus.

Thus, there were obtained transgenic A. officinalis roots, characterized by high growth rate, significant accumulation of fructans and high antiviral activity.
