Abstract

We describe a modified T-vector, pGFPm-T, for direct cloning of RT-PCR products to generate bidirectional restriction fragments for assembly of hairpin-containing RNAi vectors in the popular pFGC and pGSA binary vector backbone. Green fluorescence protein (GFP) is used as a visual reporter for direct selection of recombinants under UV illumination. The simplified cloning process enables a seamless workflow from candidate gene selection and RT-PCR verification to inverted repeat cloning, using a single pair of gene-specific primers.
