Description This is a 'Research News' article that highlights the recent developments in the area of Spray Induced Gene Silencing
RNAinterference (RNAi) technology is considered an alternative tool to develop more environmentally friendly
broad-spectrumpesticides in agriculture. In this approach, sequence-specific knockdown of gene targets in pests and
pathogensusing double-strandedRNA(dsRNA) is utilized. Two different dsRNAapplicationmethods, host induced
gene silencing (HIGS) and spray induced gene silencing (SIGS) are being followed. HIGS involves developing
transgenic plants that produce the intended dsRNA which will be delivered into the pests when they feed or grow
on the transgenic plants, while in SIGS the dsRNAs applied topically on the plants will be taken up by the target
organisms. Once the dsRNA is in the target organism, the host RNAi cellular machinery will be used to silence the
target genes. SIGS has been applied now against many pests and diseases in different crops and has given promising
results. With the development of tools that facilitate economic production of large scale dsRNA and improve the
stability and longevity of the sprayed dsRNAs on the plant surface, SIGS is a promising technology that could be
adopted across crops and against different pests and pathogens. In this research update, we provide a summary of
the recent developments in the area of SIGS with an emphasis on the examples of fungal pathogen control.
