Plant virus expression vectors and production of biopharmaceutical proteins

It is a sad fact that a leading cause of infant mortality in developing countries continues to be from infectious diseases which are quite preventable. New technologies which can both deliver vaccines en mass and without the need for syringes, … Continue reading

How do plant viruses induce disease?

Plant viruses are biotrophic pathogens that need living tissue for their multiplication and thus, in the infection-defence equilibrium, they do not normally cause plant death. In some instances virus infection may have no apparent pathological effect or may even provide … Continue reading

Not so mellow yellow

Plant viruses are often accompanied by small parasitic RNAs termed satellite RNAs. Most satellite RNAs do not encode functional proteins, yet can induce disease symptoms which range from chlorosis and necrosis, to total death of the infected plant. How such non-protein-coding RNA pathogens induce disease symptoms has been a longstanding question. Continue reading

Beating viroids at their own game

Viroids are the smallest known infectious agents and casuse a variety of diseases in crop plants. Viroid-specific small RNAs could be a way to beat them by gene silencing. Continue reading
