Suppressors of Gene Silencing

Tech ID: 99.194

Key Features

  • High Efficiency Transient Expression System for Plants
  • Methods to highly express proteins in plants in days not months


Efficient methods for expression of genes of interest in plants are required for many applications. Existing methods require the use of either transgenic plants (which are time and resource consuming) or inefficient transient expression systems. By combining suppressors of gene silencing with Agrobacterium infiltration-mediated transient expression, a rapid and highly efficient method for gene expression in plants has been developed.
