pSuperAgro™ v4 Plasmid (pBBRacdSgabT)

Introducing a new family of Agrobacterium helper plasmids, pSuperAgro™! These plasmids can greatly enhance gene transfer into various species of plants during Agrobacterium-mediated transformation. This increased efficiency provides a significant time and labor savings!

Sold as "Transformation Ready" DNA and offered at a low price to encourage rapid adoption of this exciting new technology. The purchase of this product includes a 1-year subscription to use pSuperAgro™ in your research.

pSuperAgro™ v4 was designed to include AcdS and GabT activity, driven by a single lac promoter, which both suppresses ethylene evolution and degrades gamma-aminobutyric acid (GABA) during co-cultivation. The combined suppression of ethylene and reduction of GABA significantly increases T-DNA transfer and increases transient and stable transformation frequencies in both tomato and grass plants.

AcdS activity is beneficial for higher callus induction frequency and suppresses callus browning phenomena. GabT activity decreases GABA content locally in plant cells and induces higher shoot regeneration, decreasing the number of cotyledons used for transformation and reducing the time and labor required for transformation. This plasmid has been shown to be efficacious in both Hardy Pampas Grass (E. Ravennae) and Tomato plants (S. Lycopersicum).
