Temperature-specific outcomes of cytoplasmic-nuclear interactions on egg-to-adult development time in seed beetles

The influence of temperature on cyto-nuclear effects on egg-to-adult development time in seed beetles is assessed. The findings show that environmental factors such as temperature do exert selection on cytoplasmic genes by favoring specific cyto-nuclear genetic combinations, and are consistent with the suggestion that complex genotype-by-environment interactions might promote the maintenance of polymorphism in mitochondrial genes.
