Transgene-induced gene silencing in plants.
RNAi is the most important reverse genetics tool to trigger transgenic gene silencing, which is now applied widely to investigate gene function and also practically applied to enhance resistance to biotic and abiotic stress. Recently, the most effective way to induce transgenic gene silencing is to introduce inverted repeat (IR) double-stranded RNA (dsRNA) or artificial microRNA (amiRNA) instead of a transgenic sense or antisense strand of genes. The stable transgenic plants can be acquired through Agrobacterium tumefaciens-mediated transformation of binary vectors containing an RNAi hairpin construct or amiRNA precursor backbone sequence. Here we primarily describe these two methods' vector construction, plant transformation, and transgenic line verification.
