Abstract

Epistasis - the nonadditive interaction between genes - critically determines the performance of hybrid genotypes. hybrid necrosis is an example of a deleterious epistatic interaction observed in many intra- and interspecific plant crosses. We have developed A. thaliana for the study of this recurrent phenomenon in plant evolution. About two percent of intraspecific crosses yield F1 progeny that express hybrid necrosis. several independent cases result from epistatic interactions that trigger autoimmune-like responses. i will discuss our progress in identifying the causal genes, both for several crosses with hybrid necrosis and for two non-immune hybrid weakness cases.
