Welcome to the Rebecca Nelson Lab
We study the pathology and genetics of maize diseases, from ear rots that leave carcinogenic toxins in the food of Kenyan smallholder farmers to the leaf blights that are currently wracking the temperate US.
Our work on foliar diseases is oriented toward understanding the genetic architecture of quantitative resistance. We’re working to understand how the natural allelic diversity of maize influences host-pathogen interactions. We’re identifying the genes that reduce disease, and asking how alleles that disadvantage pathogens influence other traits in maize.
Our work on mycotoxins ranges from genetics (similar to the issues noted above) to very practical work in the context of African and Indian food systems. We’re developing surveillance methods for local food systems and working on ways of sorting grain at local hammer mills to reduce toxin levels.
Our annual lab BBQ looked a little different this year, but we’re hanging in there! #2020
