The aphids have gained the ability to synthesize torulene by horizontal gene transfer of a number of genes for carotenoid synthesis, apparently from fungi.[1] Plants, fungi, and microorganisms can synthesize carotenoids, but torulene made by pea aphids is the only carotenoid known to be synthesized by an organism in the animal kingdom.[2] References1. ^ Accessed Dec. 20, 2010 {{Carotenoids}}2. ^{{cite journal | author = Nancy A.
