Lifeasible offers the state-of-the-art platform for gene-specific silencing in plants by introducing virus-induced gene silencing (VIGS).
What Is VIGS?
VIGS is one of the most powerful reverse genetics tools for rapid determination of plant gene functions and has been now used for diverse monocot and dicot plant species.
VIGS system uses viral vectors carrying a target gene fragment to produce dsRNA which initiate RNA-mediated gene silencing. Briefly, 21-25 nt small interfering RNAs (siRNAs) are produced with the help of RNA-dependent RNA polymerase (RDRP) and Dicer after viral vectors being imported into host cells, followed by their incorporation into RNA-induced silencing complex (RISC). The antisense strand of the siRNA guides degradation or translation suppression of target mRNA at the post-transcriptional level or induces transcriptional inhibition of target mRNA by RNA-directed DNA methylation (RdDM) on the promoter.
