‘The uniqueness of the interaction has implications for the development of our own adaptive immune system’

‘From Roommates to Intimate Partners’ relationship between algae, spotted salamander eggs, larva

Event has passed

Dr. John Burns of Bigelow Laboratory for Ocean Sciences will lead an online presentation called “From Roommates to Intimate Partners,” about the symbiotic relationship between algae and spotted salamander eggs and larva, on Tuesday, March 9 at noon, hosted by Merryspring Nature Center.

Many Mainers are familiar with the "Big Night" that comes near the beginning of each spring, when yellow spotted salamanders migrate en masse from their underground hideouts to their spring breeding pools. In vernal pools they mate and lay their eggs, which swell to form a dense jelly mass holding around 100 embryos each. These eggs and embryos are colonized by a tiny green alga, which have adapted to one another to both benefit from this arrangement.

“ Even more astonishing, the alga invades the baby salamander tissues and cells forming the only known such association in any vertebrate,” said  Merryspring, in a news release.

In this talk, Burns will speak about the salamander-alga association and discuss the context of why it is currently under intense scrutiny. The uniqueness of the interaction has implications for the development of our own adaptive immune system, according to Merryspring.

John Burns is a senior research scientist working at the Bigelow Laboratory for Ocean Sciences. He received his bachelor's degree in geoscience from Franklin and Marshall College in Lancaster, Pennsylvania, and a master's and Ph.D. in molecular biology from New York University. He spent five years broadening his horizons working on evolutionary biology and symbioses involving protists and algae at the American Museum of Natural History in New York before starting his own research group in Maine.

Today he continues to work on symbiotic interactions, how DNA codes the shapes of cells, and how genetic patterns influence microbe functions in the world's oceans. Learn more about his research at www.protistsystems.org.
