CMV-resistant potatoes developed
Researchers have developed genetically modified potatoes resistant to cucumber mosaic virus (CMV). The potatoes express a gene silencing construct comprising a mutated CMV replicase that confers resistance to CMV strains O and Y. The researchers used the RNAi construct to transform a CMV-susceptible potato cultivar to produce plants with complete or high levels of resistance to the viral pathogen. In those plants with high levels of resistance, infectivity of CMV-O was lower than that of CMV-Y. Details of the study have been published in the journal, Transgenic Research.
