The Great Escape: How a Plant DNA Virus Hijacks an Imprinted Host Gene to Avoid Silencing

Plant viruses are a major threat to global food security. The large family of geminiviruses has a broad pathogenic impact on economically important crops such as maize, tomato, and cassava and causes millions of tons of losses per year worldwide (Rojas et al., 2005). Geminiviruses possess a circular…

More Than Just a FAD(5): Unsaturated Fatty Acids in Chloroplasts Elicit Protective Autoimmunity

Arabidopsis (Arabidopsis thaliana) chloroplast-division mutants that have abnormally large chloroplasts have been around for quite some time, not only because they can be identified relatively easily through screening (Pyke & Leech 1991) and because their spectacular morphology sparks intrigue, but…
