Genomic Study Reveals Evolutionary Secrets of Banyan Tree and a Wasp That Coevolved With It

The banyan fig tree Ficus microcarpa is famous for its aerial roots, which sprout from branches and eventually reach the soil. The tree also has a unique relationship with a wasp that has coevolved with it and is the only insect that can pollinate it.

In a new study, researchers identify regions in the banyan fig’s genome that promote the development of its unusual aerial roots and enhance its ability to signal its wasp pollinator.

The study also identifies a sex-determining region in a related fig tree, Ficus hispida. Unlike F. microcarpa, which produces aerial roots and bears male and female flowers on the same tree, F. hispida produces distinct male and female trees and no aerial roots.
