In order to identify a promoter system for high-level expression of transgenes in hairy roots, we characterized the chimeric super-promoter fused to the translational enhancer from tobacco etch virus (TEV). Transgenic tobacco plants and hairy roots were generated with the super-promoter:TEV sequence and a modified green fluorescence protein (mGFP5) as a reporter gene. To exploit the utility of hairy root cultures as a secretion-based expression system, the signal peptide of patatin was fused to mGFP5 to direct its secretion into the culture medium.

In vitro studies demonstrate that porcine relaxin may possess various therapeutic effects. In this study, we explore the possibility of expressing porcine relaxin in transgenic tobacco. Tobacco was selected because it is a non-food, non-feed crop, and recombinant protein production can readily be scaled up.

Ricin B (RTB), the non-toxic lectin subunit of ricin, is a promising mucosal adjuvant and carrier for use in humans. RTB fusion proteins have been expressed in tobacco hairy root cultures, but the secreted RTB component of these proteins was vulnerable to protease degradation in the medium. Moreover, castor bean purified RTB spiked into tobacco hairy root culture media showed significant degradation after 24 h and complete loss of product after 72 h.
