  • Resistance genes from wild relatives of crops offer opportunities for more sustainable agriculture worldwidew

    Growing crops with stacks of two or more resistance genes from closely related species, introduced into the crop via for instance genetic engineering, combined with the simultaneous introduction of resistance management, can ensure the long-term resistance of these plants to economically significant and aggressive diseases. The combination offers opportunities to make agriculture more sustainable ...

  • Controlling resilient plant viruses with steam

    Combining steam with heat-producing chemicals could control pathogenic viruses in soil, finds new research. The study examined how effective different forms of heat sterilisation of soil were at inactivating three plant viruses. While steam alone was enough to eradicate two of the viruses, the highly resilient tobacco mosaic virus required the addition of exothermic chemicals to reduce it by 97%. ...
