How Spiderman got his Powers: A Look into Lateral Gene Transfer
Demonstrating high LGT frequency in invertebrates, Dr. Dunning Hotopp’s team detected LGT from the bacterial endosymbionts Wolbachia in over 30% of sequenced arthropod genomes. Wolbachia is an intracellular bacterial parasite/mutualist with complex host interactions. While LGT from bacteria to animals often has no benefit to a host, in certain cases it can be advantageous. For example, the coffee berry borer, a major pest to coffee growers, and the brown marmorated stink bug both have a gene originally acquired from bacteria. The gene, HhMAN1, codes for the protein mannanse and enables insects to digest plant sugars.
