Research Abstract

In the present study, two thermogenic plants, Arum maculatum and Dracunculus vulgaris, grown in England and Australia, respectively, were investigated. Our analyses suggest that both A. maculatum and D. vulgaris utilize non-chaotic regulation in their heat-production, and that components for mitochondrial respiration including alternative oxidase and specific metabolomic changes play a role in organ-specific thermogenesis in these plants.
