PG - 354-61 LID - 10.1002/bab.1373 [doi] AB - Therapeutic antibodies against tumor necrosis factor alpha (TNFalpha) have been considered effective for some of the autoimmune diseases such as rheumatoid arthritis, Crohn's diseases, and so on. But associated limitations of the current therapeutics in terms of cost, availability, and immunogenicity have necessitated the need for alternative candidates. Single-chain variable fragment (scFv) can negate the limitations tagged with the anti-TNFalpha therapeutics to a greater extent. In the present study, Spirodela punctata plants were transformed with anti-TNFalpha through in planta transformation using Agrobacterium tumefaciens strain, EHA105. Instead of cefotaxime, garlic extract (1 mg/mL) was used to remove the agrobacterial cells after cocultivation. To the best of our knowledge, this report shows for the first time the application of plant extracts in transgenic plant development. 95% of the plants survived screening under hygromycin. ScFv cDNA integration in the plant genomic DNA was confirmed at the molecular level by PCR. The transgenic protein expression was followed up to 10 months. Expression of scFv was confirmed by immunodot blot. Protein expression levels of up to 6.3% of total soluble protein were observed. beta-Glucuronidase and green fluorescent protein expressions were also detected in the antibiotic resistant plants. The paper shows the generation of transgenic Spirodela punctuata plants through in planta transformation. CI - (c) 2015 International Union of Biochemistry and Molecular Biology, Inc.
