Abstract:
Virus-induced gene silencing (VIGS) technology has become more and more widely used in various plant species for rapid screening of gene functions. VIGS does not require time-consuming tissue culture steps that are needed for stable transformation in most plant species and it can be used for studying gene function even in plants that are very difficult to stably transform. Furthermore, VIGS technology provides high gene silencing efficiency (up to 95 %) and specificity. Here, we describe a VIGS protocol that can be used for studying the functions of MAPKs and other genes in a wild tobacco species, Nicotiana attenuata. This method is also suitable for other Nicotiana species and tomato with minor modifications.

MAPK Signaling Cascades
siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
