Virus induced gene silencing (VIGS) for functional analysis of genes in cotton.

摘要

The invention relates to the functional analysis of genes in cotton by employing the Virus Induced Gene Silencing (VIGS) method. More specifically this method induces gene silencing in cotton with the help of the Tobacco Rattle Virus (TRV) vectors RNAl and RNA2 and phenotypic effects on the cotton plant can be analysed Moreover this invention also provides transient expression vector TRV RNA2 in order to transiently express genes in cotton plants and plant tissue under the influence of a strong subgenomic promoter.
