Mechanisms of rapid adaptation through the expression of “heterogenomicity”

Frank, Margaret [1], McKain, Michael [2].

Expressions of heterogenomicity across scales.

Heterogenomicity is the phenomenon in which multiple genomes function within a single organism. Hybridization, allopolyploidization, endosymbiosis, chimerism, and symbiotic and parasitic interactions are all expressions of “heterogenomicity.” Historically, genome structure, function, and expression have been studied in isolation; however, we know that much of the plant kingdom exists within a heterogenomic context. This presentation will be divided into heterogenomic interactions across varying scales. The first half of this presentation will look at how genomes interact at the organismal level, across organ systems in grafted plants and recent work to develop tools looking at genome interactions across tissue systems in plant chimeras. The second half will focus on heterogenomic interactions that occur within the same nucleus in polyploids and hybrids. The impact of combining evolutionarily distinct genomes into a single organism has wide reaching implications including the potential for rapid adaptation to environmental changes. This presentation will highlight rapid environmental adaptations that occur across heterogenomic scales.
